Hard to get the right consistancy & hard to apply

I bought this as it was on offer and substantially cheaper than the equivalent Blue Circle repair mortar. However, it seems there's a reason for that - this product is very hard to work with and very hard to apply. When you mix it up, it has a very thick consistency no matter the amount of water you add and is not like normal mortar - it just doesn't stick together. There are also lot of little bits of plastic in it, I presume to add strength to the mix. It's also very hard to apply because of the thick constancy - you have to be very careful in trying to smooth it since smoothing can pull the mixture out of the hole being filled in. It's very hard to get a good finish with this product.

Easy to use and worked well

I brought more than two tubs to fill up tile gaps in my garden. The product was easy to use and worked perfectly. The tiles and bricks are no longer moving under our feet. It looks natural and nicely.

Decent stuff

It's a decent product that is reasonably easy to work with. I found it to have a rather sticky quality, but that's not necessarily a bad thing. Makes it slightly more difficult to work with than a less sticky mix, but has the advantage of sticking to the wall pretty well. For small repairs it's more convenient than mixing from scratch.

Excellent Product

I had not done any rendering before but had researched via YouTube etc. This product worked like a dream. Super consistency, easily, workable and stayed in place with dropping off the wall. I decanted some of it into a separate bucket after mixing it dry in it's own tub for a while as it seemed to have settled in the tub. Yes, this is probably an expensive way to buy render, but it is in the right mix, and I only needed smallish quantities, and have some left over. Really pleased !!

Fantastic

I bought this render repair to repair a 2ft x 1ft patch on my old house, its reinforced with fibers easy to apply easy to smooth and texture. Cant endorse this enough to be honest, it will easily render up to 2 inches in one coat.

Great product

We have been using this for many repairs on our old house. Its very strong, stays in place as is sticky and easy to use. We have used on large render patches, holes in concrete. So many uses outside your home.
