VAPOUR BLOCK

DuROCK Vapour Block is formulated with a co-polymer styrene-butadiene emulsion. It is a trowel applied high performance coating, applied onto non-combustible substrates as an air, vapour, and moisture barrier for DuROCK PUCCS and InsulROCK Systems. The low water absorption combined with a high flexural strength makes Vapour Block an ideal water penetration barrier for use on exterior wall systems; in particular glass-fibre faced gypsum sheathing, cement board, concrete, or masonry substrates.

Roller Bear is intended for use as the first coat in a two-coat moisture barrier system that serves as the second plane of protection behind DuROCK PUCCS EIFS. Roller Bear is a factory-blended, ready-to-use, non- cementitious, polymeric coating that is supplied in 19 L (5 US gallon), 28 kg (62 lb) pails and is applied by spray, brush, or roller in a continuous layer to achieve a minimum dry thickness of 0.28 mm (11 mils) per coat.

DuROCK Polar Bear is formulated with a 100% acrylic emulsion. It is a trowel-applied high performance coating for use over wood substrates as both an air and moisture barrier, in particular for the DuROCK PUCCS RMC-1 and InsulROCK RMC-1 Systems. Polar Bear contains fibers that enhance the cohesive and tensile strength for added durability. Polar Bear can also be used as an insulation adhesive. The low water absorption combined with a high flexural strength makes Polar Bear an ideal water penetration barrier for use on exterior wall systems; in particular plywood 12.7 mm (½ inch) thick and oriented strand board (OSB), minimum 11.1 mm (7/16 inch) thick.

DuROCK Cement Bear is formulated with a 100% acrylic emulsion that is field-mixed with Portland Cement. It is a trowel-applied high performance coating for use on non-combustible substrates, as an air and moisture barrier for DuROCK PUCCS and InsulROCK Systems. Cement Bear contains fibres that enhance the cohesive and tensile strength for added durability. Cement Bear can also be used as an insulation adhesive. The low water absorption combined with a high flexural strength makes Cement Bear an ideal water penetration barrier for use on exterior wall systems; in particular glass-fibre faced gypsum sheathing, cement board, concrete or masonry substrates.
