Altro Whiterock Silicone Sealant (White) comes in 310ml tube. It is the perfect tool for filling and sealing joints. Altro Whiterock recommends that masking tape be used when applying this product to counteract overspill and protect your surfaces. Once the sealant has been applied and the excess has been smoothed away, remove the masking tape immediately before the sealant dries to reveal neat, clean edges.
