Description Product Overview Monsta Tac Monsta Tac One Step 4 in 1 Timber Adhesive is a high-performance, ready-to-use timber flooring adhesive based on advanced SiMP (silane modified polymer) technology. It is engineered to deliver a permanently flexible bond while also functioning as a moisture barrier and acoustic layer, reducing the need for multiple products on site. The formulation provides strong adhesion across a wide range of substrates including concrete, timber, existing tiles, and prepared surfaces. It is suitable for full trowel applications and is commonly used for engineered timber, solid overlay, parquetry, and timber sheet installations. The adhesive also delivers low moisture vapour permeability, allowing installation over substrates with elevated moisture levels when applied using the correct system. By combining multiple performance characteristics into a single product, it simplifies installation processes while maintaining high mechanical strength and flexibility required for timber flooring movement. Key Features 4-in-1 system: adhesive, moisture barrier, acoustic layer, and crack isolation Single-component SiMP adhesive – no mixing required Permanently flexible bond to accommodate timber movement Low moisture vapour permeability for moisture control High tensile strength and strong adhesion to multiple substrates Acoustic properties for improved sound reduction Low VOC formulation Suitable for use over underfloor heating systems Applications Installation of engineered timber flooring Bonding solid timber overlay and parquetry flooring Timber sheet and panel installations Application over concrete, timber, ceramic tiles, and stone Use in residential and commercial flooring projects Installations requiring moisture control and acoustic performance Notes Apply using V-notch or specialist Monsta Tac trowel blade Ensure full adhesive coverage and 100% transfer to flooring Install timber into wet adhesive within approx. 40 minutes For moisture up to 90% RH, use approved application method For higher moisture levels, use Monsta Tac One Day Seal and Lay system Substrates must be clean, dry, and structurally sound Do not apply over contaminants such as oil, grease, or dust Recommended application temperature approx. 5°C to 40°C Technical Information Technical Specifications: Type SiMP (silane modified polymer) timber flooring adhesive Form Single-component paste Bond Type Permanently flexible Function Adhesive, moisture barrier, acoustic layer, crack isolation Shear Strength > 2.0 N/mm² Elongation > 50% Moisture Capability Up to approx. 90% RH (with correct system) Coverage Approx. 0.4 – 0.6 m²/kg (V6 trowel) Application Method Notched trowel or specialist blade Substrates Concrete, timber, tiles, stone Application Temperature 5°C to 40°C Packaging 16 kg / 18 kg pails This adhesive is designed for professional timber flooring installations where performance, efficiency, and system simplification are critical.
