APPLICATION INFORMATION: Mix thoroughly before use using a drill mixer. Tuff Coat may be applied by Tuff Coat roller or spray. Applying excessively heavy films greater than 1500µm will lead to insufficient through-drying or mud-cracking of the paint and will yield soft paint films. Do not apply Tuff Coat on extremely humid days 32°C + 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 4°C for at leas 8 hours after application.
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. Prep all areas to be painted well with Ramuc Clean & Prep as well as a suitable degreaser. Surface must be free of dirt, loose paint, rust, oil, mildew, grease, wax, soap and any other foreign matter.
METALS: Speak to a Tuff Coat professional for advice on this surface.
CONCRETE: Must be fully cured. Concrete surface must be cleaned and etched with Ramuc Clean & Prep as well as a suitable degreaser. 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.
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, clean with Ramuc Clean & Prep 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 clean with Ramuc Clean & Prep. 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.
BARE WOOD: Sand surface smooth with 80-grit sandpaper and/or pressure wash well. Fill imperfections; sand flush and clean with a suitable cleaner and degreaser. 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.
PAINTED SURFACES: Clean painted areas with Ramuc Clean & Prep. If the old paint is an oil-based enamel or polyurethane, and is in good, sound condition, sand it thoroughly smooth with 80 to 100- grit sandpaper, solvent clean to remove residue with Ramuc Clean & Prep, then proceed with Tuff Coat UT80 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.
CLEAN-UP: Soap and water
