Dunlop Ardit Rapidset Repair Mortar 5 kg

It does what it says. A pity that it's not available in smaller quantities.

Very good product to use but there are some items to consider for best use. I can't relate to the comments about cost as for the price I think it goes a long way. I have been able to use an opened bag for a few months before purchasing a new one.We had some cracked mortar and this was the repair material we decided to use. It is clearly strong and does set fast however you need to mix the consistency you require to hold shape particularly if you are replacing vertical mortar or a larger area. Once the mortar repair starts to 'cook' it will harden very quickly.

Mix it thin or stiff depending on your job. I've used it to fill holes in brick, repair mortar in between brick and as grout for tiles. It's a 5kg bucket of powder so it goes a long way and you mix it as needed. For larger areas or jobs you would use standard mortar.
