This is my first port of call, as everyone else is so much more expensive, very rare they don’t have what you need, unlike a direct competitor

Great finish

It works well as long as it is allowed to cure with disturbance or contamination. Never goes as far as you estimate though.

Best stuff for outside grout. Very professional.

Great product for grouting the outdoor patio , which is slate paving slabs. Need to do the job during wet weather , clean out the grooves properly then wash over with clean water. Force the Sika grout into the spaces. Good stuff.

Brilliant stuff

Great stuff at a competitive price. Have seen people say that it isn't any good; that it washes out, etc. but I'd imagine they haven't COMPACTED it properly. That is key. I find it best to empty a pouch into a bucket of water and then trowel it between the paving gaps and compact it good and proper with a pointing trowel. never had any customers complain about it cracking or coming out; even after four years of having it done.

Goes in well but you must compact it well. It even says in the manual that this product should be regarded for its aesthetic performance and not it's longevity! So if using on a high traffic area, it ain't going to last long. We used it on a patio that no-one walks on, and it will come out if you scrape it with your finger. It's basically sand that sets. Looks nice but you may have to reapply every couple of years

Good stuff

Much better than the stuff I scraped out. Sets rock hard but does take several days to set, might have been because the weather wasn’t very warm though. You’ve got to really tamp it into the cavity very methodically to get a good set. Good stuff, hopefully lasts longer than the stuff originally put in by the so called professional!

Got this as I was annoyed with weeds growing between the paving slabs. I spent all Saturday cleaning the area between the slabs, making sure I followed the instructions. That was two months ago. Most of it crushed away, and the weeds came back. Waste of time and money.

Has done the job well

after wetting the sandstone pavers, the grouting went in easily enough. Used a tuck pointer to get it in and push it down well. It brushed off to a good finish and move the extra to the next area to be filled, so you don’t waist any.
If you have some left, you can put it back in the tub cover it in water and it will keep for a month. So you can get the rest done and not waste it.

It rained heavily the following day, but all was good and it has set nicely.

Easy to use and great finish
