- Features
- Excellent for concrete, masonry, fiberglass, wood, and previously painted substrates.
- Two component water-based epoxy primer.
- Simple 1:1 mix ratio.
- Chemical and UV resistant.
- Use under non-submersible and submersible Tuff Coat.
- Product Application
- Stir thoroughly before use.
- Tuff Coat may be applied by Tuff Coat roller or spray.
- Applying excessively heavy films will lead to insufficient through-drying and mud cracking of the paint and will yield soft paint films.
- Do not apply Tuff Coat on extremely humid days 90°+ RH or when rain is threatening.
- Do not apply in the late afternoon when working outdoors as the wet film may be adversely affected by dew.
- When working in cooler temperatures be sure the air and surface temperatures will remain at or above 40°F for at least 8 hours after application.
- To recoat - dry to retouch.
- Surface Preparation
- Coating performance, in general, is proportional to the degree of surface preparation.
- Follow recommendations carefully, avoiding shortcuts.
- Inadequate preparation of surfaces will virtually assure inadequate coating performance.
- Surface must be free of dirt, loose paint, rust, oil, grease, wax, soap and any other foreign matter.
- Prep painted areas well.
- Remove existing mildew with household bleach instead of ammonia.
- Product Application - Concrete
- Must be fully cured. If concrete surface has a porous texture, no further surface preparation is necessary. If concrete surface is not porous, then acid etching, sanding or shot blasting is necessary.
- Make sure to remove all remaining acid with soap and water and scrub brush. (If all acid is not properly removed, you will not create adhesion).
- Concrete should be completely clean and dry.
- Patch all imperfections, cracks, etc. with concrete patch filler and flexible joint fillers.
- Do not use silicone repair products.
- Prime with Tuff Coat UT-80 Adhesion Primer.
- After following overcoat instructions, apply two coats of Tuff Coat.
- Product Application - Bare Wood
- Sand surface smooth with 80 grit sandpaper.
- Fill imperfections, sand flush and solvent clean with thinner.
- Apply a coat of Tuff Coat UT-80 Adhesion Primer to penetrate and seal the porous grain.
- Proceed with the first coat of Tuff Coat.
- Bare wood that has been epoxied must be thoroughly scrubbed with an ammonia/water solution then sanded with 80 grit sandpaper and solvent cleaned.
- Follow with a coat of Tuff Coat UT-80 Adhesion Primer to smooth the surface and provide a uniform base, then proceed with 2 coats of Tuff Coat.
- Product Application - Bare Fiberglass
- The entire surface to be painted regardless of age must be thoroughly prepped to remove all traces of mold release agents and wax.
- Sand the gel coat with 120 grit sandpaper to a dull, frosty appearance, solvent clean with 120 Brushing Thinner to remove residue.
- If the surface is in excellent condition, proceed with a coat of Tuff Coat UT-80 Adhesion Primer.
- If the surface is rough or imperfections exist, it will have to be repaired.
- Fill all nicks and gouges, sand flush when hard, then solvent clean.
- Follow with a coat of Tuff Coat UT-80 Adhesion Primer to smooth the surface and provide a uniform base. Proceed with 2 coats of Tuff Coat.
- Product Application - Painted Surfaces
- Clean painted areas.
- Remove existing mildew with household bleach.
- Never mix bleach and ammonia.
- If the old paint is an oilbased enamel or polyurethane, and is in good, sound condition, sand it thoroughly smooth with 150 grit sandpaper, solvent clean to remove residue with thinner, then proceed with Tuff Coat UT-80 Adhesion Primer.
- If the old oil-base or polyurethane paint contained a non-skid material, scrub the non-skid surface well with cleaner.
- Thoroughly rinse the surface and allow to dry, then apply two coats of Tuff Coat.
- If the old paint is in poor condition, remove it with chemical stripper or by sanding.
- Proceed with instructions for the appropriate bare surface system.
- Mixing
- Due to the high solid’s nature of this product, there will be significant settling that occurs in the can or pail.
- Stir or shake contents thoroughly to remix any settled material.
- While applying the product, make sure to mix the product remaining in the can or pail often to ensure proper suspension of the non-skid additive into the paint film.
