Sika Setting Sand | Narrow Joint Filler, Moisture Curing Jointing Material - Suitable for All Types of Block Paving - 20kg

I've used standard kiln dried block paving sand from Wickes for years on our block paved drive, but the weeds come through and it comes out. I've used Sika 'Wide Jointing Compound' on our flagged patio and found it quite good, but its too coarse for the fine joints of block paving. Thought I'd try this for the narrow joints in the block paving and its excellent. It is very fine and dry and brushes in nicely. It does leave a fine yellow dust on the surface of the pavers when brushed on, but this dust washes off when you wet it, which you have to do to get it to set, so don't worry, the pavers won't be stained. 20kg does not go very far if the joints are properly cleaned out and then filled. Sets in about 24hrs and seems very firm rather than rock solid, but infinitely more solid than plain sand. Dries slightly grey compared to the yellow of standard paving sand, but this looks better in my opinion.UPDATE ONE YEAR ON...Just done the first jet wash on a block paved drive after I used this product last year. It has discoloured over the year, just like sand would. Some of it came out with the jet wash, especially when using the 'high pressure lance', but most of it stayed put when using a Karcher T-350 patio cleaning brush. Fairly simple job to skim over again with some more and get a reasonable looking result with less effort and mess than normal block paving sand would have been. Good enough for me to buy some more.

Used right this product is truly amazing.. the picture taken is of my mums drive that is over 25 years old and with the block paving sealant over the top this is absolutely brilliant... the sand sets on impact of water.. I used a water pump to lightly spray between the joints and left it over night to set and it did just that.. the hard work is in making sure you sweep into all of the joints and remove all signs of excess sand.. that took ages but the end finish is amazing!Sceptical about the cost initially but trust me it is worth every penny.. have had it down a few months and no sign of any weeds..

I initially jet washed my block paved drive and sprayed areas that suffer from minor weeds.Having heard that some previous reviewers said there had been slight discolouration from the sand, I decided to give the paving a coat of sealant prior to applying the Silca Sand.I applied the product by brushing into the gaps with a soft broom. In awkward areas I used a hand brush. This worked well.I then decided to use a hand pumped spray to wet the joints as the drive is on a slope and I didn’t want the sand to wash out.I then left to dry for 24 hours, before giving a further 2 coats of sealant.The majority of joints have hardened well but there have also been areas where the sand has not set and I will need to re sand.

Easy to use, works as described and is saving me a lot of hassle repairing mortar joints on the patio which are breaking up in some places but not others. The colour is not bad either and blends in with the old stuff okay. Arrived in very good time in a decent sturdy box. Very happy,

Easy to use, ideal for filling the gaps between monoblock

As another reviewer said, left white stains on my block paving. This is despite thoroughly wetting it down, so excess would run off. I have quite weathered block paving, so maybe that's the reason but no warning was given about that. Maybe a sealer should have been recommended?Also, does not fill the smaller gaps (around 1mm), so weeds can still get in and grow. Not that it matters, because weeds have started growing in the places that did fill well. Does not stop ants either.All-in-all, a huge disappointment.EDIT: 6 months later and the white stains are no longer there after the winter / spring season. More weeds are springing up now, however.

I've used this to fill between block paving, previously only filled with kiln dried sand. Do not underestimate the time and effort required in preparation to remove the weeds, moss and old sand.This is my second order and I will need more. My first 2 bags arrived as usual/ expected. I am still waiting for my 3rd. First the carrier left a failed delivery card at the wrong address. I ended up calling them and received assurance that delivery would be the following day. Have received 2 further texts advising that the delivery could not be completed. Am hoping that it will arrive on Monday.

Fantastic Product. I have quite a rustic patio, so filling does not have to be perfect. I found this so simple to use and the results are great. Has saved me hours of kneeling and mixing!!!
