This is a typical post from the new blog to do with construction in the Philippines over at :-
There is a problem with using hollowblock construction as well as plywood for ceilings and that is that cracks will form as well as gaps from installation. The solution is car body filler before painting. It makes sense but may not be an obvious solution for people who have either had cracks appear or are wondering how do they sort out a lot of these issues. Hopefully by the end of the day the ceiling will be ready for painting. The downside I found over the weekend with the car body filler though is it hardens extra fast due to the climate literally only good for a few minutes so mixing regularly and in small amounts is required. But a small quantity does go a long way and the results will pay off when finished. I am looking forward to seeing the rooms finished and ready for tiling as its all starting to take shape and looking nice. As you can also see from the photo I have already put the first coat of paint on the walls but left a cut in gap at the top for the ceiling to be painted first and at the bottom another gap due to the tiles going in and a good chance of splashing. Although the paint is waterproof etc. I would rather do the “finishing touches” once everything else is done.
