Plaster, chunna, chemical solution– most of us have tried some or all of these water leakage solutions over the years only to find dampness seep back in our home walls. Alas! But ever wondered why? These solutions, while may offer temporary relief, have limited protection against dampness because it is only a film between the plaster and the paint. If the wall has dampness coming from a source which is not diagnosed and fixed, then the effects of leakage will soon reappear.
