Dr. Fixit Raincoat
Elastomeric Exterior Wall Waterproofing and Crack-Bridging Coating for Buildings
Authorized Project Distributor — Dr. Fixit by Pidilite | Space Arc Engineering, Ghaziabad
Product Overview
Dr. Fixit Raincoat is a premium elastomeric waterproofing and decorative coating from Pidilite Industries, designed for application to exterior building walls to provide comprehensive protection against rain penetration, rising and lateral dampness, and the progressive surface cracking that develops in exterior plaster and render over time due to thermal cycling, building movement, and carbonation shrinkage. The elastomeric (rubber-like) character of the cured Raincoat film is its most important performance feature — the coating can stretch to accommodate surface cracks up to 1.0 to 1.5 mm in width that open and close with the daily and seasonal thermal movement of the building facade, without the coating itself cracking or splitting open. This crack-bridging ability means Raincoat protects against the most common pathway for water penetration in Indian external wall construction: hairline and fine cracks in the cement-sand plaster that allow rain water driven by monsoon winds to be drawn through by capillary action and hydrostatic pressure. Dr. Fixit Raincoat is also a decorative coating — it is available in a wide range of colours and imparts a smooth or textured finish to the wall depending on the variant chosen. The UV-stable acrylic binder resists colour fading and chalking under the intense ultraviolet radiation of the Indian summer sun, maintaining the appearance of the facade over multiple repaint cycles. In Delhi NCR, where buildings are subjected to intense monsoon-season rainfall, dust storms (andhi), high summer UV, and significant diurnal temperature swings, the combination of waterproofing, crack bridging, UV resistance, and decorative performance in a single product makes Dr. Fixit Raincoat one of the most cost-effective exterior wall treatment solutions available. Space Arc Engineering supplies Dr. Fixit Raincoat for residential, commercial, and industrial building exterior wall waterproofing throughout Delhi NCR and Uttar Pradesh.
Applications

Frequently Asked Questions
How many coats of Dr. Fixit Raincoat are needed and what is the correct surface preparation for application on old exterior plaster with cracks?
For application on old exterior cement plaster with existing surface cracks and possible dampness — the most common renovation scenario for Dr. Fixit Raincoat in Delhi NCR — the recommended surface preparation and application sequence is: Surface inspection and crack repair: first, inspect the full wall surface and identify all cracks wider than approximately 0.5 mm. Cracks wider than 0.5 mm should be cut out to a V-profile and filled with a flexible polyurethane sealant or Dr. Fixit Crack-X paste before Raincoat application. Cracks smaller than 0.5 mm will be bridged by Raincoat without separate treatment. Check for hollow-sounding plaster by tapping the wall — any hollow sections must be cut out and re-plastered, as Raincoat cannot hold loose plaster in place and will debond with the plaster if it falls. Cleaning: wash the entire wall surface with clean water and a stiff brush to remove all dirt, dust, algae, fungal growth, and efflorescence. For heavy biological growth (algae or moss), apply a dilute bleach solution (1:4 bleach to water) and allow to react for 30 minutes before scrubbing and washing. Allow the wall to dry completely before applying Raincoat — do not apply to wet or damp substrates. Primer: apply Dr. Fixit Raincoat Primer (or an approved acrylic primer) by brush or roller as a first penetrating coat. Allow to dry for 4 to 6 hours. Coat 1 — Raincoat: apply the first coat by brush or roller at the specified coverage rate. Ensure full wet coverage with no holidays. Allow to dry for a minimum of 4 hours at 30 degrees C (longer in humid monsoon conditions or lower temperatures). Coat 2 — Raincoat: apply the second coat in the opposite direction to the first coat to minimise holidays. Two coats are the minimum — for facades with significant cracking history, three coats are recommended for maximum film thickness and crack-bridging reliability.
How long does Dr. Fixit Raincoat last on exterior walls in Delhi NCR and what maintenance is required to extend its service life?
Dr. Fixit Raincoat is designed and tested for an exterior service life of approximately 8 to 10 years under normal Indian climatic conditions when correctly applied at the specified minimum dry film thickness. In the specific conditions of Delhi NCR — intense UV radiation in summer, heavy monsoon rainfall, dusty andhi storms, and temperature swings from 2 to 3 degrees C in January to 45 to 46 degrees C in May — actual service life varies depending on the original application quality, the colour selected (darker colours absorb more UV and may show earlier chalking than lighter colours), and the level of maintenance. To extend the Raincoat service life: annual inspection: inspect the exterior wall surface each year (ideally before or after the monsoon season) for signs of coating failure including chalking (white powder on the surface), cracking, blistering, or loss of adhesion (hollow-sounding areas). Cracked or blistered sections should be cut out and re-coated before water infiltration causes further damage to the plaster behind. Cleaning: wash the wall every 1 to 2 years to remove dirt, algae, and pollution deposits that reduce UV resistance and accelerate surface degradation. Re-coat: at year 7 to 8, the original Raincoat film will have thinned from UV degradation and may begin to lose its crack-bridging capacity. A wash-down and re-coat with a fresh application of Dr. Fixit Raincoat at this stage (one to two coats) restores the waterproofing performance and refreshes the decorative appearance for a further 8 to 10 year cycle at a fraction of the cost of full replastering.
