Specially formulated for Click or T&G Glue Floors. CalFlor was the first American manufacturer to introduce a floor adhesive certified to meet the tough European D3 standards for flooring! Reformulated to include NO formaldehyde or acrylamide (common T&G glue additives) and has a certified low VOC content. This improved formula has the same water-resistance, high strength and flexibility of our original D3/Type II Eurobond glue.
