Stormdry Repointing Additives (500 ml)

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 –

Is a concentrated liquid that is to be used as a diluted part of the gauging solution in sand and cement mortar. It is used for repointing before a Stormdry Masonry Protection Cream application. It enhances the waterproofing qualities of a standard sand and cement mortar mixture whilst still allowing it 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.
