Toupret Masonry Repair Filler - Weather-Resistant Powder Filler for Exterior & Damp Masonry - No Shrink, Shapeable Deep Fills - Paint-Ready in 48‑72 hours - Cement-Based Repair Powder - 1.5kg

I was worried this product would let me down. I was really happy when I was proven wrong. I used this to build and sculpt a broken wall corner. Easy to use, the wall looks great and it's set to a rock hard finish. No crumbling, not dusty. After sanding I put a coat of peel stop over the top and a generic masonry paint to seal it as you can't use resin based paint on it bare. I also used this to fill in cracks in the wall... The wall is rendered with concrete so it's like a shell. Theres a crack all the way along the edge where the top meets the side. I used my fingers to rub the paste into the crack and then moulded a thick layer to build the edge again and add strength.. it's solid I can't see it breaking anytime soon. My next job is my window sil and I'm looking forward to it. Hope this helps someone.

This exterior filler is superb. Very easy to work with and rubs down a treat. I have found that adding a bit of PVA really helps the mix and makes it less powdery when you sand it. Really top stuff, highly recommended.

Good stuff and easy to mix in small amounts. Useful to fill quite deep holes...but it takes a lot longer than stated to dry and has a somewhat powdery finish. Only given 4 stars as it is quite hard to sand it once dry. It is not waterproof. The filler dries to a cream colour. Does not slump either 👍

Item arrived on time.Really sets well and dries quickly.

Easy to mix and spread, didn’t set too fast and was easy to clean up tools after. However coverage information doesnt seem to be on the packaging we found this only did about 1m sq. area. Sets to a light grey colour.

I did a fair bit of research before settling on this. I needed it to fill deep recesses in a sandstone wall, and subsequently drill structural fixings into the filler. Due to access limitations it was two weeks between application and drilling, but appeared set within a couple of days. It was mid grey in colour once dry. It took 80mm concrete screws very well and the installation is very sound. Would definitely recommend for the right projects.

As others have said it dries quickly and is workable for around 30mins. A good product

Worked well when I used this to fill in cracks in render on an exterior wall. You don't need a lot. Hint: Mix in small batches and don't make it too wet. Fill cracks proud, then sand smooth once dry. It does a shrink a little, as I found out.
