Sika Path and Patio Sealer – Protects Against Weathering and Green Growth – 5 Litre

My grey paved drive is 5 years old, was never originally sealed and so covered with moss in the joints and algae on the paviour faces. It looked a mess. Pressure washed then re-sanded (make sure the paviours are bone dry otherwise the sand drags). I left it a week in warm weather, and tested a small patch to see if the kiln sand slid in. It did. So re-sanded one day, and sealed the next in August 2020 as the weather was forecast to change and wanted it done. Best tip online is to use a leaf blower before sealing to help rid of excess sand. Don't worry if seems too much sand is blown away, the sand only needs to be between blocks not up high. Also don't need whacker plate as only topping sand up. NB. there are different shades of kiln sand, at different builders merchants, it depends what they can get apparently. I never realised and had to exchange 2 bags of reddish sand for blonde sand like the original as red looked awful with grey paving. Apologies I digress.... now to the BLOCK SEALER. Sika seal very easy to use, like a white PVA/acrylic liquid, goes on bluey white, dries quickly and invisibly on a hot day. Cut in edges by walls with paint brush, then first coat with roller, second with garden pump spray. It dries rock hard, as evidenced on sand blown off edge of drive when I poked it. Very pleased as it felt it might wash off at first rain when you first put it on. Close up photo is finished drive. Not glossy, but has enhanced paviour a little bit, bear in mind it was never done before, so the sealer was really sucked in. I feel it's protected now. I may do another coat or two as not too expensive to buy, and do prefer a sheen look. Amazon has great price on this when compared to other suppliers/products. Happy to update. Time will tell ☺️ good luck all, it's a very satisfying job done 👍🏼

The Sika patio sealer easy to apply by roller or spray but the roller preferable as seems to cover more evenly and work into the surface, in fact also seems to use less liquid than spraying. Once applied a second coat can be made after about two hours which is needed, my use was for a concrete patio and obvious one coat inadequate, the sealer is sticky, odour and appearance very similar to diluted PVA adhesive but does take 24hrs or more to dry completely dependant on temperature, expected rainfall should definitely be avoided. After drying the sealer does leave a waterproof, Satin shine clear surface that is fairly resistant to abrasion by footwear or lightweight traffic of any kind such as plant pots in my case. The present persistent rainfall of the past few weeks does give indication a third coat may be needed as would I expect do regular bi-annual coatings also, however for the present the sealer seems effective in it’s protection of the concrete stain used and providing water resistance to the concrete surface.

This is a quality product for sealing your patio. My patio is 5x5 meters & I managed to give it 4 coats applied with a lambswool roller. Multiple coats leaves the patio with a lovely sheen, but follow instructions carefully ie beware of weather forecast so you don't apply it if rain is imminent. Recommended product

OK I've had my patio laid a few years ago, and I've been struggling with dirt and algae every year, I have my jet wash machine, however this year the algae was much more, and the moss much more, I decided I need to seal this stone and try to protect it. The price is decent, the delivery was next day, I'm quiet happy so far! I probably didn't use the product collected, however, i used a roller to apply it as recommended, however, i kept pouring some ans using the roller to make sure its applied all over and in-between the slabs, about 30minutes later it was all dry, in the evening I watered my lawn, a bit of water splashed on the stone, i noticed clearly water remained on the surface, and was not absorbed by the stone. I did a one generous coat but did not do a second one, that consumed half the gallon, so I guess if I feel I need a second I can still do it with the remaining. The area was about 16square meters. Sone Slabs.

Easy to apply. I had quite a large area and the 1 bottle was enough. I even had a bit left over. I did point the area before using this. It was easy to apply, I poured into a paint tray and used a roller on an extendable pole. Weeds and moss are growing back through though. I'm not sure if this is down to how bad the weeds are in my garden as it used to be one big rockery when I moved in so they're very strong. I've only had it applied for a few months so I can't comment on how well it lasts for protecting against dirt and grime. Will update after the winter months.

Easy to apply. Covered a massive area in minutes and still have loads left

This really is a good patio sealer for the price. It’s also water based so easy to use and spread. I first used it three years ago on some concrete patio slabs. I did three coats for the wet look, although two I’m sure would be fine if you just want to cover it. I was sceptical about how hard wearing it would be as it was water based - but after three years it still looked good. I have just put on another coat to give it the new wet look again as it was beginning to look faded although continued to work as a sealer by stopping all the dirt and grime from settling. Last year I sealed another patio at the back of the garden made from Indian Flagstone and put on three coats. This had the effect of a Matt finish and seemed to not resist the winter staining as much. However it was very easy to wash off. After two more coats earlier in the year it now has a little more of the wet look coating and appears to work as well as the concrete ones. I suspect being water based it soaks in to the stone layer more easily and you just need a few more coats.

I'm not a DIY'er but braved rolling this on my new patio. Followed instructions for my natural stone, so a second coat applied less than 2 hours after the first - actually within 30 minutes. Works a treat, when applied as instructed, and the next day really saw the difference. Highly recommended
