Application conditions Temperature should be between 50F. and 85F. during application. Air humidity below 85%. Avoid painting in too much wind or sun. A rapid loss of solvents will occur under these conditions and will decrease the flowing ability. Add thinner up to the specified percentage to compensate for the faster release of solvents.

If existing paint system is intact and only loss of gloss is noticed, one or more fresh coats of Epifanes Polyurethane Topcoat may be applied on a well cleaned, degreased surface that is sanded with 320 grit wet or dry abrasive paper. If required use Epifanes Epoxy Primer first. A paint system in poor condition must be removed. If subsequent coat is applied within 48 hours, sanding between coats is not necessary. The application by airless spray is not advised.
