Tarmac Multipurpose Mortar, 5kg Bag

Another reviewer says it's like damp sand, but it's supposed to be! Follow the instructions and don't add too much water. I find a hand-held garden fork, and a large bucket, to be perfect for mixing this. Remember it's mortar, not glue, and that it cures, not dries out. It'll set in damp conditions, as long as you protect it from rain for at least a day. It doesn't bond things as such, it surrounds them and holds them down. It's also brilliant for filling gaps. I found applying it with gloved hands, to be easier than a trowel, and a gardening trowel to be easier than a mortaring trowel. And also, don't get the 5kg size, get 25kg, or you'll run out.

Easy to work with and you just mix it do the work required.

Great stuff, quick and easy to use. Highly recommended.

THOROUGHLY mixed contents of bag before opening.
Mixed about 1/5 of bag with cold tap-water to do some emergency pointing of brickwork at about 7pm. Weather was dry and warm.
I immediately noticed something odd about the mixture, I would no stick to my trowel when turned on its side, the small amount of mixture just slid off like damp beach sand!
The following morning about 8am, the mixture hadn't set! It was still soft, and a screw-driver would easily push into it, again like it was beach sand that was slightly damp!
Not until about 5 days later had the mixture hardened significantly, but was crumbly like a Crunchy chocolate bar.
Bought in mid June 2018, returned remaining bag in early July 2018
Got a refund but staff said they'd never had any complaints, despite a few other comments on here.
This isn't the first product I've bought from B&Q that didn't set properly. Diall interior powder filler set like chewing gum!!

I used this to patch up some gaps between pavers but also have used a couple of the larger bags in the past to repair a wall (neither job had I ever done before). This works well but take care not to add excessive water.
