- Ready-to-use straight from the cartridge, for interior and exterior use
- Water-resistant: Long-lasting waterproof repairs
- Suitable for the repair of damaged pointing sealing cracks to prevent rain penetration and plugging DPC holes
- Blends in visually with Sand mortar; Other colours can be matched by rubbing the mortar with dust from the substrate
- Crack Resistant: Increased flexibility allowing contraction and expansion of adjacent construction materials without cracking;
- Note: If the Stormdry Xr Mortar is too thick to come out of the nozzle, cut off the end of the nozzle to make it easier to squeeze the material out. Occasionally if the cartridge is very cold it could thicken up, place the unopened tube in a bowl of warm water to warm the mix up before use.
