Surface Preparation
Proper roof preparation is essential for a successful coating application.
- The roof surface must be clean and free of all loose and oxidized material, dirt, oil and other contaminants.
- Thoroughly and carefully use a power blower or a stiff bristle broom and/or power wash the roof surface. (Do not power wash if the roof has any water leaks.)
- Seam tape all cracks, seams, flashings, skylights, vents, etc. For older roofs and/or roofs with cracking, alligatoring, failing systems, and minor leaks use polyester roofing fabric to reinforce the roof system. (See Application Specification).
- Each application should be done in one complete step to form one seamless layer over the total area being covered. Apply with roller, squeegee, brush or airless spray equipment. If applied by spray, A-3025 Underseal must be back rolled. Do not thin.
Poly-Fabric (Seam Tape) Application (A-3025) Joints, Seams, Etc.
- Seam tape over ALL joints, cracks, seams, around vents, over flashings, caps, pipes, and skylights, etc. Cracks over 1/16 inch wide should be cleaned and caulked before reinforcing.
- Brush a coat of A-3025 Underseal over the joint or seam.
- Roll polyester seam tape into the wet Stretch-Guard A-3025 Underseal. While still wet, apply another coat of A-3025 Underseal over seam tape completely embedding tape in the coating. Allow drying.
- Apply 1 or 2 full coats of A-3025 Underseal overall seam tape applications.
- Allow drying.
- Apply A-3025 coating the surface at a rate of 1 to 2 gallons per 50 sq. ft to cover and fill in rough surfaces and pinholes.
Poly-Fabric (Full Coverage) Application
- Apply a liberal coat of A-3025 Underseal.
- While still wet, embed the polyester fabric into the A-3025 Underseal.
- Apply a second coat of A-3025 Underseal to saturate the fabric (2 gallons per 100 sq. ft. is required).
- It is recommended that another coat of A-3025 Underseal be applied over dried fabric system to smooth the rough surfaces.
Top Coat Application
- Apply 2 coats of Americrete’s A-3050 Elastomeric Coating as a finish coat at the rate of 1 gallon per 100 sq. ft.
- Apply a third coat if desired.
- Fill all cracks and crevices.
- DO NOT APPLY OVER MILDEW. A solution of 50% household bleach and 50% water will kill the mildew.
Concrete/Plywood Walking Decks
- Use the appropriate Americrete Waterproof Deck System for best performance.
Heavy Duty Waterproofing System
- Poly-Fabric Seam Tape application. (see instructions)
- Apply primer Coat of A-3025 Underseal at 1 gallon per 50 sq. ft.
- Apply A-3025 Underseal embedded in the polyester fabric with 1-2 additional coats of A-3025 Underseal.
- Apply 2 coats of Americrete’s A-3050 at a rate of 1 gallon per 100 sq. ft.
If products are sprayed, it is recommended that the first coat be back-rolled. Always cross hatch 2nd coat.
Metal Roofs (See Application Specifications)

- Seam tape all seams.
- Apply 1 coat of Americrete primer first at 50 sq. ft. per gallon.
- Apply 2 coats of A-3050 Americrete’s at 1 gallon per 100 sq. ft.
Urethane Foam Roofs (See Application Specification)

- Do not open the roof system.
- Seam tape and patch all blisters and sump areas with A-3025 Underseal until the surface is smooth.
- Coat with 2-3 coats of A-3025 Underseal until smooth.
- In areas of standing water apply 2 coats of embedded fabric with A-3025 Underseal with 2 more coats of A-3025.
- Apply 2 to 3 coats of Americrete’s A-3050 at a rate of 1 gallon per 100 sq. ft.
