Our house firewall is in need to be waterproofed. What is the best paint or waterproofing solution for this already painted firewall. Painted with white paint (basic coating i think, i don't know the exact name of paint used). Eh tumatagos ang tubig pag malakas ang ulan, so it really need a waterproofing repair.
One engineer told me about Super ThoroSeal Wateproof coating ( http://www.thoroproducts.com/pdf_info/INF_SUPR_3.06.pdf ) which can suitable for pre-painted concrete wall such as my firewall. But according to its main website, it says there that it is NOT ideal for painted surfaces (MUST NOT be applied to painted surfaces). Ano po talaga ang suitable? Any help please. And available ba sa philippine market itong product na ito? Or if is not advisable, any other product/brand you can recommend. Thanks...

How to waterproof already painted firewall?
I think you need to check out some waterproof paints in the market. (ACE Hardware or Handyman has it.) Ideally, you need to fit in the color of the firewall with the color of your waterproof paint. In that way, you would be able to do paint it. For the brand, well it depends on the color and on the size of the firewall.
