HPRS1L 1L Thompsons High Performance Roof Seal - Black

My son used this, together with flashing tape, to seal my leaking garage roof. Several weeks on it appears to have solved the problem, although due to its age the roof is likely to require recovering with roofing feltat some stage. The solution was easy to apply with no problems incurred.

Does what it says on the tin!

Effective product, easy to use and apply

Used this to seal a leak on a flat felt roof around circular hole going into downpipe. Applied three coats. Been tested two or three times in fairly heavy rain and seems to have sealed leak.

looks nice when its going on but did not last a year

I have used this paint before and can recommend it, east to apply and does the job. Fast delivery.

Got this for my bay window which is felt-covered, after a good stir it goes on very easily with minimal odour & dries within six hours, it's good stuff and recommended.

I've used this product for painting over leaks in my shed and garage roof. The garage was concrete sheets with a leak somewhere on an arwa of flashing. Two coats and has been good for 6 months now. The shed was a metal sheet roof with a leak where the two sheets overlapped. Couple of coats on the join and solved.Also used for waterproofing a bit of concrete where pooling water ended up masking the garage floor damp. Early days but looks good there too.I finished the tin and am now ordering a second to have in stock for any issues over the winter.I used the 1L tin. Doesn't cover a huge area but a nice solution Would recommend. Jus
