I'm after something like Thomson's Roofseal to seal some old corrugated
cement roofing boards which appear to absorb water and drip through. I was
looking through the Screwfix catalogue and saw "Stabilising Solution
Concentrate", "Waterseal concentrate" and "Flexacryl Roof Repair Compound".
The concentrates look like a nice idea, as its only a couple of sheets which
are a problem, and I'd prefer not to use a lot of the proper black sticky
stuff as its a large roof, and 2 coats would go through it quickly (and at
£20 a tub, that's not terribly cheap) - plus, it would change the colour and
be a big job.
So - would any of those concentrates be suitable for trying to stop water
penetration of old cement based sheets?
