Archie 182 - 5 / 5 - 07/05/2025

Good product

I needed to make some repairs to a bedroom wall and fill a new socket chase which is why I needed “Hardwall” and not undercoat as I would be plastering onto bare masonry. Easy to mix with a good working time makes this ideal for a novice like myself very happy with the results. Just don’t forget to scratch the surface before it sets

Great product, as expected

Great product and will be used a lot in our home renovation. I'm not sure if this already exists, but a half size bag would be great to make it easier to lift.
