A certain amount of repointing will usually be necessary when dealing with rain penetration problems in masonry walls. This is because small cracks in the mortar course and cracks in the interface between the mortar and brick/stone can acts as pathways through which rain can penetrate. In many cases, only localised sections of mortar will require repointing. However, where the mortar is in particularly poor condition it may be necessary to repoint the whole wall.

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.
