I hope you can help me with a roofing / flooring problem that I have.
The roof in question is a 3m x 3m(approx) flat greying asphalt roof area on a purpose built victorian maisonette. This walled roof area is intended to be used as a patio space for the person living on the top floor (us), and as such serves as both a roof to the flat below & a patio for us. There were a few dips & marks on the asphalt where furniture has sunk a little into it in the past.
Last weekend my girlfriend decided (for purely aesthetic reasons I understand) that she wanted to re-paint the light grey, stained asphalt & bought some Feb Aquaseal Protective Roof Waterproofer on the advice of a friend who has a similar roof. She then asked me to paint it on to the patio area which I've done, though only one coat so far. There is a problem however, as I think she's bought the wrong product: for an area that is to be used as a patio, the Aquaseal waterproofer gets extremely tacky on warm days, to the point that the roof area becomes useless as a patio as the black stuff comes off on shoes, furniture etc.
Naturally, I've now been asked to fix it!
There are a number of options that I can see:
1. Paint over the Aquaseal waterproofer with a more suitable alternative product
2. Remove the Aquaseal waterproofer & re-paint the asphalt with a more suitable alternative product
3. Install wooden decking to the area
4. Cover with sand or thin slabs
5. Re-asphalt the entire area
My preference (in my ignorance perhaps) is either option 1 or 2, as 3 & 5 seem to be expensive & will require professional contractors, and 4 would likely result in a gooey mess on hot days. If my preference is correct, then could you give me any advice on the 2 parts of the job: painting over (is this possible?) or removing the Aqauseal (will White spirit damage the underlying ashphalt, even in small amounts? Is there any other chemical or process I could use?), and then re-painting with a more suitable product (Which product?). As you can see, it's a bit of a sticky situation, if you pardon the pun...
I would be grateful for any advice or help!
