Siroflex Rainproof Acrylic Caulk is a one component high quality flexible sealant based on acrylic emulsion, which is immediately rainproof after application. It is almost odour free and is not corrosive towards metals. After application it forms a soft flexible rubber type seal. Conforms to ISO 11600 F12,5P.
Siroflex Rainproof Acrylic Caulk is ideal for the sealing and filling of gaps and cracks where movement can occur such as those between wooden and metal window and door frames, painted wood, anodised aluminium, PVCu, brickwork, concrete and aerated concrete.
Surfaces must be clean, dry and free from dust, grease and other loose material. SX Rain Proof Acrylic Caulk can be diluted and used as a primer for highly porous surfaces prior to application. Cut the cartridge seal and screw on the nozzle which should be cut to your required size. Using a skeleton gun, apply the sealant into the gap or joint ensuring a good solid fill. Tool using a spatula or stick wetted with neutral soapy water within 5 minutes of application. Uncured sealant can be removed with water. Can be painted over with emulsion paints after 1-2 hours providing a skin has formed. For oil based paints allow 24 hours before painting. Clean tools with water.
