Safeguard Stormdry Repointing Additive No.2 500ML

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.

These block water ingress whilst still allowing the mortar to breathe.
