Step 1: Prepare
The first thing you would do is prepare the substrate. Remove any loose crumbly substrate; make sure the substrate is clean, dry, free of any previous applied products, and foreign matter. For best results steel, aluminum, and fiberglass should be sand blasted. This will give the best surface texture for a life-time adhesion and maximum durability. If sandblasting is not applicable, one may try to replicate that surface using coarse sand paper.
Step 3: Patch
Patch and profile any joints, seams, cracks, holes and rough areas using LRB/TAV mixture (Liquid Rubber Base, Thickening Activator). Wall/floor junctions require a 1” bead of LRB/TAV mixture. 2-parts LRB is mixed with 1-part TAV to create the thickest mixture possible (similar in viscosity as silicone caulk). Wall/floor junctions require a 1” diameter caulk bead of LRB/TAV mixture. Most cracks and seams use a 3/4″ diameter caulk bead of LRB/TAV mixture. LRB can be used by itself (as a liquid membrane) to smooth out and/or level any horizontal surface and can be used like a coating over vertical and inverted surfaces.

Step 4: Broadcast Granules
4. Apply 1 coat of PermaFlex (240 sq ft per gal). While the PermaFlex is still wet, broadcast the Rubber Granules onto the wet coating (0.25# per sq’). When the PermaFlex has cured you will have bonded the Rubber Granules in place. Excess granules should be removed by sweeping, blowing, or vacuuming.
Step 5: Apply Liquid Rubber Base
5. Apply 1 coat of LRB (80 sq ft per gal) over top of the Rubber Granules. This coat will encapsulate the Rubber Granules and bind them together. Once the LRB has cured enough to walk on, proceed to the next step.
