Q. Emulsion paint got split on to the roof tiles of my front porch, I’ve done everything and I cannot remove the paint from the tiles, as it seems to have soaked in. Do I have to replace the roof tiles?
A. If you wanted the paint to stick it probably wouldn’t, but there you go. My suggestion is to re-paint the porch roof tiles. Simple as that. Choose a superior quality exterior masonry paint that matches all the rest of the roof and mix in a product called E-B (Emulsa-Bond) 50:50 into the paint. E-B acts like a stir-in glue that makes paint stick to otherwise questionable surfaces. Pick a reasonably good day and apply one good coat directly to all the tiles. When that dries, if the ‘bad tiles’ are adequately covered you are finished. (Usually one good coat does the job)
If you can still see some of the offending paint looking through, apply another coat of the exterior emulsion, but this time without the E-B. (only use E-B in your first coat). You should end up with a fresh looking new porch roof. Lots of people actually repaint their faded and tired looking old roof tiles using this method. (Please bear in mind, working on roofs can be very dangerous, so don’t even think about it if you are not very capable and have all the proper access equipment, ladders etc)
