Acrylic Waterproofing Coating Grey - 5 KG

This is like a very thick gloopy paint it can be a bit tricky to put on but once it's been smoothed into place and dries it acts as an extremely effective barrier I had a bit of a leak somewhere in the seam of some felt and no matter what I tried I couldn't get it to seal properly. I finally tried this based on other reviews and it worked absolutely brilliantly. we've had the worst storms in a century and not a drop of water came in

Excellent solution to waterproofing my garage roof. Would definitely buy again.

Lots of glowing reviews for this product and after using it I can see why.I have a very old (about 60 year) corrugated asbestos roof on my garage measuring 7.4 metres by 6.5 which had become porous, and cracked. I looked at various options, even replacement but disposing of asbestos, even the fairly innocuous reinforced cement stuff is crazy. The cheapest was to cover with the same profile grp or fibre cement panels but even these would cost around £1000 and then all the bolts would need to be cut off and replaced to allow the covering panels to sit properly adding about another £100 to the price over and above the difficulty of getting into some of the less accessible ones.I had previously coated the roof with bitumen which worked for a couple of years but as it began to crack and flake, the water started to come in again so I was back to square 1, in fact even minus one as I now had a lot of bitumen to remove. I scraped as much off as I could, pressure washed the roof to get it as clean as possible. Bought just the one 5kg tin to try it out and see what coverage I would get. It does say 1 to 2 sq metres per kilogram but in my experience these claims are often exaggerated.I applied it with a cheap 3" brush and it went on a treat. Much easier to apply than I expected after reading some of the reviews and really not that much different from ordinary paint. I applied it generously and then measured the area I had covered. One strip 86 cms wide by 7.4 metres and on the next strip 1 metre wide and I got 3 metres before I ran out of paint so this gives me just slightly over 9sq metres. In fact, if you allow for the corrugations the total surface area covered is likely over 10 sq metres so the claim of 1 to 2 sq metres per kilogram is more than justified. Just managed to get the job finished as, even at 11 am in was getting too hot to apply the paint.That evening it started to rain and has done all night. Not one drop of water anywhere under the bit I have painted which was by far the worst part of the roof.I am mightily impressed with this paint. Time will tell if it is a permanent solution but I will soon be ordering another four tins with discounts for buying quantities about another £100 to complete the job.

This is the second paint i have bought . A cheap alternative to stop leaks on a flat roof . I put it on thick with a brush and it sealed small cracks and waited till it rained to find that the leaks had stopped thankfully

Great Product, Nice and Thick covers well, seals joints nicely. Used it on my Fibre Glass flat roof , which had a leak somewhere couldn't see where it was. Applied this stuff and no more leaks .I have started to paint the whole roof with it now as a preventative measure.

I use this every year to coat a flat roof extension . It is easy to apply and does the job. The roof has lasted 35 years so far. It reflects the sun so doesn't get too hot. It's quite thick, I use a large paintbrush and it goes on well.

Great paint. Mixing takes some time and effort as the paint is thick. Coverage appears as stated on the tin. The colour is slightly lighter than I wanted but did the job.

Does exactly what it says on the tin. It is very thick to apply but with an old paint brush and perseverance it does a nice job. Takes a few days to dry fully in cold weather.
