Application

out to ensure that the repointing mortar can form a good bond.


After shaking the bottle, Stormdry Repointing Additive No.2 should be diluted with clean tap water before use in the ratio 1 part Stormdry Repointing Additive No.2 to 4 parts water by volume. Greater concentrations are not recommended. The resulting gauging solution should be added to the chosen mortar mix to attain workability.


To avoid shrinkage it is important to add the gauging solution carefully to ensure that only the minimum quantity necessary to attain workability is used. Once mortar has started to set and has become unworkable it should not be reworked by adding more gauging solution. For this reason, only small batches of mortar should be mixed at a time.


Before the repointing mortar is applied, raked out mortar joints should be wetted – e.g. by flicking water using a wet brush. The repointing mortar should be applied into the raked out joint using a suitable pointing iron or repointing gun and tooled firmly. Where deep mortar joints are being repointed this may need to be done in two stages to achieve good compaction.


Wherever possible it is beneficial to tool the mortar to a “bucket handle” finish as this provides the best durability and weathertightness.
