Imagine 2 veranda's outside the front of the house, 2 levels, the top veranda floor has tiles, grouted sitting on top of villa-board. Over the years, the grout has seen some wear, and water now seeps through in some areas, pooling on the villa-board before dripping onto the lower level.
One solution we have been entertaining is painting the tiles (outside, and exposed to weather and UV) with liquid rubber paint. The questions I have are:
(a) Can you advise the best tile cleaner, primer and paint? Brand please. The area to cover is 12x3mtr.
(b) Does the paint come in a variety of colors?
