StormdryWaterproof Express Repair Mortar - Pack of 2 - Ready to Use Cement Mix 310ml Tube, Grey Sand

This is amazing stuff. So easy to use. Needed mortar patched up on coping on flat roof. Scraped out loose mortar and filled with this. It is waterproof and makes a lovely neat finish. Left to dry 4 hrs on sunny day then was able to use Stormdry cream to seal coping

Great product, highly effective. Would buy again.

Did the trick repointing bits of a wall which masonary bees were starting to eye up. You need more than you think, that’s not really a fault of the product, and a lot less messy than mixing mortar, but can get expensive. Wear plastic gloves when using.

Easy to use

great product. dries very quickly and gives a good seal.

This is difficult stuff to work with. Even warming up the tube on a radiator - per previous TA reviews - it's still very difficult to get the stuff through the nozzle as it's so small. I managed it in the end by cutting half the nozzle off, so making the hole bigger. The stuff itself was good, after all the frustration of getting it out of the tube.

Works well provide waterproof seal

Ejects easily and smoothly. If put on at the recommended thickness/width and flushed off it sets ok in less than a couple of hours. If put on thicker/deeper than recommended it may take a couple of days to cure fully although it skins over in a few hours. However, if it gets severely wet during that time it will run, so a couple of dry days may be necessary to be sure. I used it for filling a variety of sizes of cracks and gaps when repairing an old sandstone wall where I couldn't get a mortar mix deep enough into the gap. Can be coloured to match by softly brushing dust across the joint before it skins over.
