Grinding is very good. Acid Etching is also suitable. If neither are used it is best to do a sample patch and test adhesion after overnight cure.
Our standard system is a thinned out sealer coat of E2100 water based epoxy to colour, followed when hard enough to walk on by a solid coat of E2100 unthinned and into which the flake is cast. Some Applicators prefer to use just one coat of E2100 and flake into it.
Some applicators prefer E4110 100% solids Epoxy. This is normally applied in the same manner, with the first coat thinned out a little with E122 Epoxy Thinners. The Flake is cast into the second unthinned coat, working from the far corner a metre or two at a time.
Broadcast the flakes with a seeding action until there is 100% coverage and no basecoat showing. Leave preferably overnight to dry.
Using a stiff broom sweep the floor or vacuum to remove the excess. Then carefully scrape the floor with a clean floor scraper or sand with 180 # sand paper.
Apply by brush and roller until the whole surface is evenly covered. Don’t allow the E2000 to pool. The dry areas which are short of flake can be carefully touched up at this time.
Apply second coat E2000. If gloss for exterior use required use E8472 waterbased Polyurethane Gloss. If satin for exterior use required, use E8470 Clear Satin. If extraordinary chemical resistance required, use E8480 Fluoro Modified Polyurethane
If left longer than 12 hours lightly sand between coats.
A Polyurethane will continue to cure for weeks. We recommend mats be placed under car tyres for the first month.
N.B Some recent tyre formulations tend to have a stain. Some applicators of recommend only dark flake on this account. A & I Coatings is currently doing extensive research to combat this problem.
