15mm premium grade engineered oak flooring installation to three brand new luxury townhouses in Highett, VIC 3190. Bostik moisture sealer were applied to the concrete slab prior to floor being laid. Bostik Moisture Seal is a two part, high performance, water based epoxy moisture and vapour barrier formulated to prevent water seepage and permeation in building and construction substrates. After full cure, moisture test of the concrete was done and timber floor were left on site to acclimate. Floorboards then were laid directly to the slab using Bostik Ultraset SF adhesive. Bostik Ultraset SF exceeds the acoustic requirements as an intermediate layer between subfloors and flooring systems.
