SikaBlock Paving Fix For Narrow Paving Joints, Buff, 20kg

Sika is a leading brand in construction, therefore I knew this would be a quality product I could trust. Very easy to follow instructions on the packaging. It may seem costly but not having to weed the block paving every few weeks is worth the expense and has given my old block paving a new look. If like mine were the joints are full of dirt and moss there will be some hard, but beneficial work to remove before using the sand. The sand is very fine and fills the gaps easily. Once the gap’s are full clear any excess by sweeping diagonally across the joins to avoid removing the sand from them. Then simple dampen with a fine mist spray with either a hose or fine rose on the watering can. You can walk on the surface but the sand does take a day or two to dry.

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 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.

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

This stuff Is good at lasting long in the joint as it describe. And does stop weeds from growing in the joint to an extent. But weeds and moss started growing on stop of the join I found after a while. Wouldn’t say it’s worth the price tag. But it’s better than just normal joint sand. Easy to use.

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

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 :)

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.
