Single-Coat Application–Whenskimcoatingandllingminor
voids in concrete and wood substrates, mix Planipatch with
water (A) or diluted Planipatch Plus (B).
Two-Coat Application – When using Planipatch as an
embossing leveler or to patch over properly prepared cement
terrazzo, ceramic tile, existing VCT or existing non-cushioned,
fully adhered residential sheet vinyl flooring, mix Planipatch
with full-strength Planipatch Plus (C) for the first coat. Then
mix Planipatch with diluted Planipatch Plus (B) for a second
coat.
