Bostik UltraSet® 3 in 1 has extremely low moisture vapour permeability and is not adversely affected by moisture. As a result, costly and time-consuming concrete moisture testing is not required when the slab is properly prepared, fully cured and dry to touch. UltraSet® 3 in 1 includes Bostik’s Blockade® antimicrobial protection, which inhibits the growth of bacteria, mould or mildew on the surface of the cured membrane. The cured membrane resists stains and deterioration caused by moulds. The elastomeric properties can bridge cracks up to 3mm, which can occur in the substrate prior to or after Installation. This superior elasticity allows the adhesive to move with the wood as it expands and contracts with changes in humidity and temperature over the life of the floor. UltraSet® 3 in 1 contains Bostik’s patented Thickness ControlTM Spacer Technology. This propriety feature helps ensure proper membrane thickness is maintained between the hardwood flooring and substrate. Installers can use mallets to engage the tongue and groove or even walk on their work during installation process without significant reduction in the film thickness that could compromise moisture protection and sound control. UltraSet® 3 in 1 provides a premium sound reduction barrier over the substrate that typically outperforms 3mm rubber underlay. This eliminates costs associated with the labour and materials required to transport and install these secondary acoustical sheet membranes.
