The first thing you would do is prepare the substrate. Meaning remove any loose crumbly substrate, make sure the substrate is clean, dry, free of any previous applied products, and foreign matter.

Step 2: Prime

Prime Coat Rubber Membrane Pool Coating


Prime the substrate with 1 coat of PermaFlex (240 sq ft per gal). Cement block surfaces need 2 prime coats of PermaFlex. This first coat of PermaFlex will penetrate into the substrate thencure as tough as a tire. This penetration enables Sani­Tred PermaFlex to permanently adhere to the original substrate for the life of the structure. Shown using light grey.

Step 3: Patch

Patch and profile any joints, seams, cracks, holes and rough areas using LRB/TAV mixture (Liquid Rubber Base, Thickening Activator). When 2­parts LRB is combined with 1­part TAV you will have a thickened mixture that can be applied at ANY thickness in one application. Wall/floor junctions require a 1” diameter bead of LRB/TAV mixture and most cracks use a 3/4′′ diameter bead. LRB can be used by itself (as a liquid membrane) to self level and smooth out any rough horizontal areas.
