Application Description
HOW TO USE : 1) Remove cap carefully, holding can away from face. Carefully screw the nozzle fully onto valve. Do not force the nozzle onto the valve (refer to the Additional Safety Precautions below if the nozzle won't screw fully onto valve). 2) Moisten surface with water to help the foam cure and expand (e.g. with plant sprayer). 3) Shake can vigorously approx. 30 times to mix contents. 4) Apply light pressure first to check if valve is working properly. Vary pressure to adjust rate of foam release. Start filling from the lowest point shaking can occasionally during use. Do not overfill - the foam will expand to 2.5 times the initial volume. 5) If building up in layers, spray lightly with water between layers to help fully cure and maximise expansion. 6) Remove fresh foam spillage immediately with nail varnish remover (test on a concealed area first). Cured foam can only be removed mechanically. 7) Foam will be tack free in 15 minutes, surface dry in 30 minutes. It can be cut, sanded, plastered or painted after 12 hours. 8) If exposed to sunlight, the foam must be painted or coated.
