Don't believe the negative reviews. Read the instructions. Make sure you shake the container first. Clean and dry the surface to be seaked.
I poured the (milky looking) solution into a mop bucket and brushed the solution on with a soft yard brush. Work it in well. Don't leave any milky solution sitting on the surface.
Do a second coat in about 20 minites after completing the first. Do a third if you can but I only managed 2.
The rain now beads on the top and it looks fab.
works really well

I wouldnt worry too much about the negative review. I would imagine they applied it incorrectly. Just follow the instructions and you're good. The difference is shocking. Just look at my before and after photos. I recommend cleaning the patio beforehand on a hot day. I used a spray cleaner that removes concrete and mortar but diluted it. I wanted to make sure I removed any thin resedue or film from when I pointed the slabs. I then used a paint pad to wipe on and did 3 coats (would have been 2 but it was about 30 degrees and it was evaporating really quickly. Just make sure you do all the coats within 30 mins.

I bought this product from Carmarthen store yesterday. Took it home and tried it on a small piece of my black limestone. I brushed it on and it dried a white colour. Totally spoiled the limestone. I would keep well away, stick to a good branded name you can trust, you will pay more but trust me it's worth it. Took back to stir they were very helpful and gave me my money back
