We've noticed a few water marks on the plaster board ceilings in a few rooms since the rains started to come a month or so ago. Nothing too big or major. probably 5 or 6 in total, a few CM in diameter. One long one that is around 20cm long and, but narrow.
I wanted to leave them for the rainy season as the marks would highlight which part of the roof is leaking. I may or may not do that, as there are another few month of sporadic rain storms to come.
So it come to sealing a roof.
Google shopping shows loads of different types of roof sealants, mainly they seem to be acrylic. Some in squirty tubes, some in tubs.
Which types of sealants are usually good?
Is it a case of getting up there and cleaning out around each tile, and then squirting the sealant around each one?
Or tub, and apply it all over the tiles with a roller is better?
TIA.
