Rated 5 out of 5 by Good coverage and tough Better coverage than you might expect. Covered a tatty felt roof 15m square in an afternoon by brush using two 5kg tins with a bit left over. It is very treacly and you are almost daubing or spreading it rather than painting so not sure how easy it would roll - a dip and splat on seemed the best approach as over brushing brings the fibres to the surface if you try to brush it too thin. Thinners are very pungent so you don't want to be down wind or too close to it. I can still smell it oudoors after 24hrs and it is still a bit tacky. Feels like it will be very tough. Expect to chuck away any kit you use or get it on. Rained after application but it just shrugged it off so seems like a good choice. 29 Jul 2016
Rated 5 out of 5 by Brilliant stuff Old garage roof cement sheeting was cracked in places and letting water in. A search on screw fix for a temporary solution led me to give this product a try. Put on a pair of marigold gloves over a thinner latex pair and got on with the job on a warm sunny day. The flexacryl was easily spread with a large paint brush and has fixed the leaky roof a treat. Highly recommend this product. 10 May 2016
Rated 5 out of 5 by ideal solution to roof leaks An excellent product that does the job perfectly. If applied correctly you will get more coverage than it says on the tin. it's not easy and it takes a lot of working in but the end result is a dry roof. .The bonding fiibres enabled this product to bridge fairly big cracks - something that bitumen paints will not do. Common sense dictates wearing gloves. 22 Apr 2016
Rated 5 out of 5 by great coverage Easy to apply and thick enough to use in strong winds without it blowing all over you. Very impressed but I can't say about the results yet as I only applied it yesterday. Judging by the finish though I can't see a problem. 3 Feb 2016

I've applied 1 coat onto a concrete balcony and all seems good however I'd like it to have another coat for belt and braces. Also cause it will have occasional footfall. Has anyone applied more than one cost ( cause the tin says one coat) does it nicely adhere to itself? Thanks in advance.

Normally one coat of Flexacryl is sufficient but you can apply a second coat and it will bond to itself once the first coat is fully cured. A second coat is normally applied to flat roof where pooling water is occurring. Outside of this the product is not designed to take foot traffic apart from maintenance purposes, however loose laid promenade tiles can be put down for more regular foot traffic.
