External Wall Waterproofing

The external walls face the direct brunt of rain and other changes in weather. Therefore, it is not enough to just decorate the building, but also waterproof it.

Waterproofing Knowledge

  •  There are cracks on the external walls through which rain water is seeping inside the house and ruining my interior décor. How do I resolve it and stop seepage?

    If the cracks are small and there is no problem with the structure, use a flexible crack filling compound, Dr. Fixit Crack X for filling the cracks.

    This is a ready to use water based acrylic crack filler that seals the crack up to 5 mm.

    If the cracks are more than 5 mm, use nonshrink crack filler Dr. Fixit Crack X Shrinkfree.

    Painting is possible after 24 hours. Unlike cement that permits seepage, Dr. Fixit Crack X is waterproof and is ideal for small cracks.

It is a UV resistant coating and does not attract dirt. Its high sheen makes it look new for years to come. The coating is available in 700+ attractive shades to add beauty to building exteriors.
