Roof Waterproofing FAQs

Dr. Fixit recommends a root-resistant, durable waterproofing coating for green roofs and terrace gardens, since plant roots, constant soil moisture, and regular watering create more demanding conditions than a standard exposed terrace. The waterproofing layer needs to be applied and fully cured before soil and planting material are added, as repairs become far more difficult once a garden is established on top. A drainage layer above the waterproofing membrane is also important to prevent water from pooling against the coating under the soil.

Dr. Fixit prevents flat roof seepage with a flexible waterproofing coating, such as Dr. Fixit Pidifin 2K, applied across the entire slab after cracks are repaired and the surface is properly cleaned and primed. Flat roofs are particularly prone to ponding water since there is little to no slope to drain rain away naturally, which makes a durable, water-resistant coating and clear drainage outlets especially important. Regular inspection after each monsoon helps catch early coating wear before it develops into active seepage.

Dr. Fixit recommends inspecting the terrace for cracks, worn coating, or blocked drains well before the monsoon begins, since waterproofing application needs dry weather and time to cure properly before facing continuous rain. Cracks should be repaired with Dr. Fixit Crack-X Shrinkfree, followed by a flexible coating such as Dr. Fixit Pidifin 2K applied in multiple coats over the cleaned, primed surface. Starting this process at least a few weeks before the rains gives the coating adequate curing time and reduces the risk of leaks during peak monsoon.

Dr. Fixit recommends a more robust waterproofing system for RCC slabs in high-rainfall zones, since these roofs face longer periods of standing water and sustained saturation than areas with lighter rainfall. A flexible, crack-bridging coating such as Dr. Fixit Pidifin 2K, applied in the recommended number of coats with attention to drainage slope and outlet placement, helps the slab shed water efficiently rather than letting it pond. In regions with especially heavy or prolonged monsoons, more frequent inspection and recoating helps maintain protection over the years.

Dr. Fixit approaches waterproofing in old buildings by first assessing which areas have failed over time, commonly the terrace, external walls, and any wet areas, since older structures often have layers of previous repairs that need to be removed before new treatment. Cracks that have widened with age or building settlement are repaired with Dr. Fixit Crack-X Shrinkfree before a waterproofing coating is reapplied. Retrofitting an old building's waterproofing usually requires more extensive surface preparation than treating new construction, since existing coatings, plaster, or tiling may need to be addressed first.

Dr. Fixit Pidifin 2K is formulated for concrete roof slabs, offering a flexible coating that bridges the fine cracks that develop as RCC expands and contracts with temperature and bonds well to properly prepared concrete. It is applied in multiple coats over a cleaned and primed slab, forming a seamless membrane that resists ponding water and sun exposure across monsoons. For slabs with existing damage, crack repair should precede coating for the system to perform as intended.

The best paint for exterior walls is the one that prevents water ingress and protects against harsh weather. Among various options available out there in the market, Dr Fixit Raincoat range is considered the best paint for walls. However, it is a highly advanced waterproofing solution that offers waterproofing, crack bridging, and colour retention for long-lasting durability in heavy rain conditions.

Yes, Dr Fixit Raincoat WPC works as a waterproof wall paint but offer much better and sustainable results. It has advanced formulation that provides strong protection against water seepage. This waterproof coating creates a thick, flexible layer on the wall that resists cracks and weather damage. It helps keep exterior walls safe from rain and moisture when applied correctly with proper surface preparation.

Yes, elastomeric paint like Dr. Fixit Raincoat Select is excellent for waterproofing because it creates a thick, flexible film on exterior walls. This elastomeric waterproofing paint bridges cracks and resists rain and harsh weather. It also prevents water penetration and protects the structure, making it highly reliable for long-lasting wall protection.

Dr. Fixit Raincoat Classic is considered the best paint for home walls because it protects exterior walls from rain, moisture, and cracks. This outside wall paint forms a strong, flexible layer that resists algae and fungus, keeps walls clean, and helps maintain colour for a long period, even during harsh weather.
