EpoxyFlex Coverage Guidelines

Coverage Rate Utilizing a minimum of 3 gallons per 100 square feet, the EpoxyFlex Roof Coating System, which includes embedded WeaveFlex fabric, must result in a minimum final dried coating thickness of 24 mils (.024).

Coverage may vary, requiring up to 5 gallons per 100 square feet, depending on the roofing material condition, and/or the surface thereof (i.e., cleanliness, absorption rate, surface texture, age, roof topography, protrusions, influence o fuse, etc.).

See EpoxyFlex Coverage Guidelines for minimum requirements on specific roof types. It may be necessary to apply an EpoxyFlex topcoat at a rate of 1 additional gallon per 100 square feet to ensure minimal required thickness in all areas of the roof. Coating coverage requires about 50 percent more coating for walls, protrusions and vertical or angled planes than for horizontal planes. For single-coat EpoxyFlex applications, coverage varies between 1 1/2 to 4 gallons per 100 square feet.

CAUTION: Care must be taken to assure that neither to little or too much coating is applied at one time. No single liquid application should be applied to exceed a dried film thickness of 40 mils (.040).

Unacceptable Conditions to Applications The following are unacceptable conditions: • un-adhered bridges

• unsaturated or exposed polyester fabric

• puddles or blobs of coating

• too little or too much coating applied at one time EpoxyFlex

Recommended Equipment

Recommended Equipment for the EpoxyFlex Roof Coating System

FOR BEST RESULTS For best coating adhesion and rapid application, it is recommended that the EpoxyFlex Roof Coating System be applied with airless spray equipment in conjunction with a large squeegee, heavy-duty paint rollers, and/or roofing brooms.

Minimum Requirements

As a minimum requisite, it is possible to apply the EpoxyFlex Roof Coating System with a paint roller, squeegee, and/or roofing broom only. The use of roofing brooms/squeegees with paint rollers is acceptable as long as the coating is rolled down and complete saturation of the fabric is achieved. In most instances, roofing brooms or squeegees are easier to use. However, roofing brooms leave an uneven and non-uniform surface. All surface applications shall be finished with a roller.

Heavy Duty Rollers

Rollers used should be of the highest quality and heavy duty. • Rollers should be 18 inches wide with a support on each side of the roller. • Standard 9-inch wide rollers may be used for small jobs, depending on personnel, job size, tool quality, and other conditions. • The roller nap should be a minimum of 1 1/4 or 1 1/2 inches.

Airless Spray Equipment

Airless spray equipment must be heavy duty as follows: • Airless spray equipment ratings should be at least 3 gallons per minute at 3000 p.s.i., and be able to handle 120 K.U. material. • The airless hose should be a minimum 5/8-inch inside diameter for an application utilizing 150 feet or less. Consult with airless pump manufacturers for hose size requirements [inside diameter to length] when using lengths longer than 150 feet. • Use a reversible tip in an average size from .028 to .050 thousandths. Again, consult with airless pump manufacturer for capacity and capability. Exact size requirements may vary, depending upon several factors, such as pump capacity, roof surface topography, vertical lift between pump and application surface, hose length, temperature, personnel, etc.

Rating		3/GPM @ 3000 P.S.I
Hose Size Minimum (Inside Diameter)	150 Feet or Less	5/8" inside Diameter with 1/2" stringer line
	More Than 150 Feet	Consult with Equipment manufacturer
Reversible Tip Size **		28 to 50 mils (.028 to .050 Inch) ** Exact Size may vary. Consult with equipment manufacturer

 

 

OPTIONAL ITEMS

Smaller rollers for small jobs: Depending on personnel, job size, tool quality, and other conditions, it is possible to apply the EpoxyFlex Roof Coating System using standard 9-inch wide rollers.

Paint Brushes: A paint brush may simplify many applications, especially on roof protrusions such as pipes. A paint brush is optional, but not a replacement for rollers. A paint brush used alone without rollers or roofing brushes cannot ensure proper adhesion.

EpoxyFlex Roof Coating System WeaveFlex Fabric

EpoxyFlex Roof Coating System Without WeaveFlex Fabric EpoxyFlex Roof Coating System without WeaveFlex fabric is an inexpensive alternative to high energy costs, frequent roof repairs, and replacement. Applications using EpoxyFlex without WeaveFlex are for structurally sound, monolithic surfaces and pitched roofs. Warranties for EpoxyFlex without WeaveFlex are job specific and only available by contacting Infinity Performance Products. Standard warranties for the EpoxyFlex Roof Coating System are not available for applications of EpoxyFlex without WeaveFlex. EpoxyFlex without WeaveFlex may be applied as a single coat or as a two coat installation. For best results, both structurally and cosmetically, two coats applied separately is preferred. Two coats will enhance coverage uniformity, color coverage, and monolithic coverage security. Coverage: EpoxyFlex Roof Coating without WeaveFlex requires a minimum coverage of 2 gallons per 100 square feet that results in a minimum dried film thickness of 16 mils (.016). EpoxyFlex without WeaveFlex may be applied in a one-step process only when the resulting dried film thickness is a minimum of 16 mils (.016).

Step 1: Prepare the Surface to be Coated Be sure the coating surface is completely dry, structurally sound, water tight, clean, and clear of dirt, oils, rock, soap, or any substance or circumstance that may impair adhesion.

Step 2: Apply First EpoxyFlex Coat Apply the first EpoxyFlex coat using a heavy nap roller (required) at a minimum rate of 1 1/2 gallons per square foot. Vigorously roll coating into the cap sheet, integrating any loose aggregate or dust in a uniform coat. The rolling action of the coating shall be in two directions, 90 degrees to each other. In addition to the heavy nap roller, if desired, it is permissible to use spray equipment or a roofing broom for more rapid application.

Step 3: Wait 24-48 Hours hours minimum or until the first coat is dry to the touch following that period of time.

Step 4: Apply Optional EpoxyFlex Color Coat The EpoxyFlex color coat application is with a minimum of 1/2 gallon per 100 square feet, or enough coating to obtain 4 mils (.004) dried film. 25

EpoxyFlex Roof Coating System on Parapet Walls & Roof Protrusions

EpoxyFlex Roof Coating System Parapet Walls and Roof Protrusions Before the EpoxyFlex Roof Coating System is applied to the roof, the System must be first applied to all roof protrusions, the entire tops and sides of parapet walls and other vertical surfaces, details, pipes, stands, and all such items. Coverage: Apply EpoxyFlex coating at a rate of approximately 2 to 3 gallons per 100 square feet. Coating coverage requires about 50 percent more coating for walls, protrusions, and other vertical or angled planes than for the flat or horizontal roof sections. Allow 50 to 75 percent additional coating on all drip edge or gravel stop receiving a wrap-around treatment of WeaveFlex fabric. (For estimating purposes, multiply the drip edge’s linear feet by .75 and add result to the total of coating surface square feet) EpoxyFlex Coverage on Roof Protrusions & Parapet Walls

1st EpoxyFlex Coat 2-3 gallons per square

2nd EpoxyFlex Coat 2-3 gallons per square Minimum Required 24 (.024)Mil Thickness

Step 1: Apply first EpoxyFlex coat Begin application by using sprayer or roller, applying first to parapet walls, pipes, stands and other vertical protrusions. A small paint brush may facilitate application. On parapet walls and other flat vertical surfaces, apply EpoxyFlex to cover the top of wall, the vertical surface, the surface where the dissimilar planes converge, and at least one foot out onto the roof deck or horizontal plane as shown. Be sure that parapet wall caps have been removed, it they are removable. Cantilevers: At intersections of vertical and horizontal planes, place cantilevers adhered both to the vertical and horizontal planes. All ‘cants’ (caulking, mastic, waterproofed press board, foam, etc.) shall be flat or concave in relation to the adjacent surfaces and form a smooth contiguous waterproofing line from vertical to horizontal planes. Vigorously roll coating onto exposed surface integrating any foreign material (dust, small aggregate, etc.). To assure saturation of any surface imperfections and to maximize contact with the roof’s waterproofing element, roll EpoxyFlex’s primary coat in two directions, 90 degrees to each other.

Step 2: Embed WeaveFlex fabric Parapet Walls: It is preferable to embed WeaveFlex first on any perimeter parapet walls that may exist. Stand the WeaveFlex fabric roll on end to facilitate rolling and embedded it onto the parapet walls. Set the fabric into the wet EpoxyFlex coating at the top of the parapet wall (vertical plane) and let it drape over onto the wall and out onto the deck, extending a minimum of 12 inches (1 20 foot) on to the deck and into the strip of EpoxyFlex coating. If it is not possible to embed the fabric on top of the parapet wall, it must be embedded the full height of the wall or vertical surface. Along the length of the wall, immediately roll the fabric into the wet EpoxyFlex by vigorously rolling or brushing, with strokes 90 degrees to the roof deck. Then embed the remaining fabric into the coating on the roof deck or horizontal plane with vigorous strokes embedding the fabric into the EpoxyFlex. Be sure to roll towards the vertical wall to avoid pulling the fabric away and assuring sufficient fabric where the vertical wall and roof deck intersect. Roll out air pockets, bubbles, folds, wrinkles, excess coating and assure full fabric penetration. Immediately apply the second EpoxyFlex coat, described Step 4, massaging or rolling the coating into the fabric in the same direction as the first coat. On any second and successive WeaveFlex courses, overlap the fabric at least two inches. Pipes and other round protrusions: Finger cut WeaveFlex at least six inches long so that the fabric, when wrapped around the protrusion, will adhere flat against the protrusion and the strips will lay flat on the deck. Cut a hole in a piece of fabric the same diameter as the protrusion and lay it over the deck covering the fingers. A slit may have to be cut in the overlay or multiple pieces may have to be used to surround the protrusion and cover the finger strips. On the second and successive courses, overlap the polyester fabric at least 2-3 inches.

Step 3: Apply Second EpoxyFlex Coat Immediately apply a second EpoxyFlex coat on top of the fabric at a volume of 1/2 to 1 gallon per 100 square feet. Apply enough coating to saturate the fabric and make a dried film of at least 24 mils thick (.024). Imperative: Vigorously roll EpoxyFlex coating into fabric with even strokes. Apply strokes with heavy pressure as follows: Horizontal Planes: Start stroke in the center and pull to the edge of the WeaveFlex fabric or seal the lapping edge and then start strokes about 6 inches from sealed WeaveFlex edge and pull at a 45-degree angle to the WeaveFlex fabric course direction. Vertical Planes: Apply at a 90-degree angle to the WeaveFlex fabric course direction. Begin strokes within six inches of fabric edge or dissimilar plane and pull to the opposing fabric edge. Roll out air pockets, bubbles, folds, wrinkles, excess coating, and assure full fabric penetration. The second coat should saturate and completely cover the fabric.

Step 4: Finish EpoxyFlex System Continue process until a monolithic coating, embedded with WeaveFlex fabric, entirely covers each vertical plane and roof protrusion.

5. Application of the EpoxyFlex Roof Coating System. For best results, both structurally and cosmetically, the EpoxyFlex Roof Coating System should be applied in two separate applications. The first application is with WeaveFlex polyester fabric. The second application is a color coat that should be applied twenty-four (24) to forty-eight (48) hours after the first application is dry to the touch. The EpoxyFlex Roof Coating System can be applied in one (1) application and still meet warranty specifications. The majority of the following details a two (2) application system.

5.A. Apply enough coating, compensating for absorption, irregularities in the exposed plane, etc., to cover the surface and fill the polyester fabric (approximately 1.5 to 2. gallons minimum per 100 square feet).

5.B. Apply coating in sections approximately 15 to 20 feet long and 4 inches wider than the polyester fabric. The applied coating pattern shall be 2 inches on each side of the polyester fabric.

5.C. Vigorously roll coating onto exposed surface integrating any foreign material (dust, small foam cells, etc.) in a uniform coat. The rolling action of the coating shall be in two (2) directions, ninety degrees (90°) to each other.

5.D. Immediately, while the first coat is wet, roll out the polyester fabric into the wet coating. Pull the fabric tight and reset the fabric into the wet coating. E. Immediately apply a second coat on top of the polyester fabric. Apply second coat at a rate of 1/2 to 1 gallons per 100 square feet. Apply enough coating to completely fill the weave pattern of the polyester fabric and make a dried system of at least 24 mils thick.

5.F. Vigorously roll coating into polyester fabric. Apply heavy pressure to roll out all air pockets, bubbles, folds, wrinkles, excess coating, and to assure full fabric penetration. It is imperative to smooth out all wrinkles and bubbles with the roller by pulling from the center of the fabric at no less than a forty-five degree (45°) angle.

5.G. On the second and ensuing courses:

5.G.1. Follow all previous instructions;

5.G.2. Overlap the polyester fabric at least 2 inches; and

5.G.3. Continue process until a monolithic coating covers the entire project. The rolling action of the coating shall be in two (2) directions, ninety degrees (90°) to each other.

5.H. The second application is a color coat that should be applied twenty-four (24) to forty-eight (48) hours after the first application is dry to the touch. Apply the second coat at a rate of 1/2 to 1 gallon per 100 square feet to facilitate a total minimum dried film thickness of 24 mils (.024)

6. Twenty-four (24) to forty-eight (48) hours after the final coating has dried to the touch, replace all parapet caps, flashings, and removed materials. Seal the edges and nail heads of all flashing and coverings. It is desirable to coat all such flashing and coverings.

7. Unacceptable conditions to applications are:

7.A. Un-adhered bridges;

7.B. Unsaturated or exposed polyester fabric; and

7.C. Puddles or blobs of coating.

Non-Laminate Coat System

NON-LAMINATE COAT SYSTEM

1. EpoxyFlex is an inexpensive alternative to high-energy costs, frequent roof repairs, and replacement. See your local sales professional or an Infinity Performance Products representative for your special needs. Coatings without polyfiber reinforcement are for structurally sound monolithic surfaces and pitched roofs only. Certain foam roofs qualify for a non-laminate coat system, as approved in writing by Infinity Performance Products, Inc.

1.A. The coating surface shall be completely dry, clean (clear of dirt, oxidized or discolored foam, oils, rock, soap, or any substance or circumstance that may impair adhesion), structurally sound and watertight.

1.B. Coating application may be in 1 or 2 coats (passes or applications). Total quantitative coating must be a minimum of 2.5 gallons per 100 square feet at sixteen mils (.016) minimum dried film thickness, and the minimum mil thickness of each coat is eight mils (.008) dried film thickness.

1.C. For best results, both structurally and cosmetically, non-Fabric applications should be applied in two (2) separate applications. Two separate applications enhance:

1.C.1 Coverage uniformity;

1.C.2. Color coverage; and

1.C.3. Monolithic coverage security.

1.D. When applying 2 coats, the first coat shall receive a minimum of 1.5 - 2 gallons per 100 square feet. The rolling action of the coating shall be in two (2) directions, ninety degrees (90°) to each other. The second coat shall be applied twenty-four (24) to forty-eight (48) hours after the first coat is dry to the touch. The second coat's application is with a minimum of 1/2 - 1 gallons per 100 square feet or enough coating to obtain a sixteen mils (.016) dried.

1.E. Though a heavy nap roller is required, spray equipment or a roofing broom for penetration and rapid application is recommended. Vigorously roll coating into cap sheet integrating any dust or small, loose foreign material in a uniform coat with the heavy nap roller.

1.F. Non-laminate coat system applications may occur in a one (1) step or application when applied as described above and the finished dried mil thickness is a minimum sixteen mils (.016)

2. Apply EpoxyFlex Mist Coat over entire roof. This procedure is highly
recommended for maximum bond over all smooth surfaces (including metal
surfaces). EpoxyFlex is an oxygen cure product, this light coat application will
cure very rapidly and provides a very tight, immediate bond to the surface,
which then acts as an anchor for the full system application during its curing
process.
A. If using spray equipment: Hold spray wand 24 to 36 inches above surface and move
wand rapidly back and forth so as to leave a light (not solid) misting coat over the
entire surface and allow to dry thoroughly 10-40 minutes depending on atmospheric
conditions and temperature.
B. If using a roller: Roll over the entire surface using a roller that is not fully saturated
with product, roll out just enough product so as to leave a light (not solid) layer on
the surface. EpoxyFlex is an oxygen cure.
3. Application of the EpoxyFlex Roof Coating System. For best results, both structurally
and cosmetically, the EpoxyFlex Roof Coating System should be applied in two
separate applications. The first application is with WeaveFlex polyester fabric. The
second application is a color coat that should be applied twenty-four (24) to forty-eight
(48) hours after the first application is dry to the touch. The EpoxyFlex Roof Coating
System can be applied in one (1) application and still meet warranty specifications. The
majority of the following details a two (2)-application system.
A. Apply enough coating, compensating for absorption, irregularities in the exposed
plane, etc., to cover the surface and fill the polyester fabric (approximately 1.5 to 2
gallons minimum per 100 square feet).
B. Apply coating in sections approximately 15 to 20 feet long and 4 inches wider than
the polyester fabric. The applied coating pattern shall be 2 inches on each side of
the polyester fabric.
C. Vigorously roll coating onto exposed surface integrating any foreign material (dust,
etc.) in a uniform coat. The rolling action of the coating shall be in two (2)
directions, ninety degrees (90°) to each other.
D. Immediately, while the first coat is wet, roll out the polyester fabric into the wet
coating. Pull the fabric tight and reset the fabric into the wet coating.
E. Immediately apply a second coat on top of the polyester fabric. Apply second coat
at a rate of 1/2 to 1 gallons per 100 square feet. Apply enough coating to completely
fill the weave pattern of the polyester fabric and make a dried system of at least 24
mils thick.
F. Vigorously roll coating into polyester fabric. Apply heavy pressure to roll out all air
pockets, bubbles, folds, wrinkles, excess coating, and to assure full fabric
penetration. It is imperative to smooth out all wrinkles and bubbles with the roller
by pulling from the center of the fabric at no less than a forty-five degree (45°)
angle.
G. On the second and ensuing courses:
1. Follow all previous instructions;
2. Overlap the polyester fabric at least 2 inches; and
3. Continue process until a monolithic coating covers the entire project. The rolling
