Rated 1 out of 5 by from Beware Beware - You have to use all of this jointing compound in one application you cannot store any leftovers whatsoever, an important fact that Bostik do not mention on the tub, I only found out by phoning their Technical Department and asking how to store leftovers.

Rated 5 out of 5 by from Repointing of patio pavers Excellent product - really very easy to apply and a great looking finish. Ideal for me as a DIY novice. If I can you - anyone can! NOTE - the unit is 15kg despite the 20kg photo

Rated 4 out of 5 by from Better support needed. I used this as a repair grout and time will try if it is better than a cement mix. There are very limited instructions on the pack and they refer only to a new build scenario. You must wear rubber gloves to handle this product which has the consistency of melting sugar.

Rated 5 out of 5 by from Excellent Product This is an excellent product and is very easy to use, no mixing required can use straight out the bag. I have just finished re-pointing my patio so only time will tell how well it stands up to the elements. My only criticism is that it is supplied in only one bag, so if you don't use it all what is left will go off. It would be better if it came in two bags.
