About this product
Shaw TotalWorx 3-in-1 Ultra is a one-component, 100% solids, cross-linking MS-polymer flooring adhesive that does three jobs in a single troweled layer: bonding the floor, inhibiting concrete moisture, and providing sound reduction and crack isolation. It is not an underlayment and not three separate products. Which jobs you get depends on the trowel and spread rate, so the same pail covers roughly half the area when it is used as a moisture barrier. Shaw states it is solvent and isocyanate free, non-flammable and low odour, with a VOC content of 0.5 grams per litre, and that no subfloor moisture testing is required when it is troweled as a moisture barrier, subject to substrate preparation and the terms of Shaw's separate concrete moisture remediation warranty. Sold as a 4 gallon pail with a clip-on trowel blade included.
