Stormdry Repointing Additives are designed to enhance the waterproofing characteristics of mortar mixes used for repointing. They are diluted with water before being used as a gauging solution. Two types are available: Stormdry Repointing Additive No. 1 - This contains a blend of silanes and siloxanes (similar to those found in Stormdry Masonry Protection Cream). These block water ingress whilst still allowing the mortar to breathe. Stormdry Repointing Additive No. 2 - This repointing additive is polymer modified giving allowing it to impart excellent waterproofing characteristics to repointing mortars and enhanced bonding characteristics between the brick/stone and the mortar. Unlike Stormdry Repointing Additive No. 1 this additive does not allow the mortar to breathe.
