SikaBlock Paving Fix For Narrow Paving Joints, Buff, 20kg | Previously Known As Sika Setting Sand – Resists Weeds – Sets Hard – Moisture Curing

This was easy to brush in and set well . So far it seems to be suppressing weeds but it’s only been in for a week . You do need to take time to brush off the excess before wetting it or it will leave a film on top.

Used this on a large area of block paving. Very easy to apply, dump a pile on the blocks and using a soft brush sweep forwards and backwards to persuade it into all the cracks. Coverage was excellent on an area of approx 4x10 metres and there was still a reasonable amount left in the bag. Used a hose pipe on fine spray setting to wet afterwards and there was some settling but generally stayed near the top of the cracks. The warning: Our block paving is several years old and was jet washed about 4 years ago and again just before applying the setting sand. Jet washing will wear the surface of the blocks and this opens up pores for the sand to cling to. I had to stand back and look at the area I'd just brushed and vigorously brush any parts that looked like there was a concentration of sand on the surface of the bricks. Even brushing hard did not lift all the sand from the blocks however and there were still areas of paler bricks. I think this was inevitable given the condition of the blocks and although it is obvious I can live with it. I'm hoping with further wear or jet washing this will lift and return all the bricks to a uniform colour. Don't expect perfection, ants lifted some out before it had set properly and there has been one very small weed growing in a crack. There were large areas of significant moss growth in the cracks before I jet washed it and the acid test will be if and how soon this returns. Fingers crossed :)

Super easy to use, sets really quickly and is good VFM.

The order arrived late. But it works.

Great product, sets well, and looks to have set blocks well, be careful if gaps are small and not put down too much, have finished mine with two coats of sealer and it now looks as good as it was when laid

Nice to use, very fine sand. It has set hard been down several weeks now. The ants have pushed it up in a few places ha & the weeds are still growing through it unfortunately. I did put weed killer down everywhere beforehand. So is disappointing as I'd hoped it would prevent completely. It does leave a slight colour on the bricks, so be careful when using. I took my time & tried to pour it in all the joints. I'd buy again though

This product is brilliant. I used it last year and hardly any weeds. Just make sure you clean all excess sand off the block paving otherwise you will not get that sand off. I have purchased another bag just to top up the block paving joints.

Does the job well
