RAINCARE PU CLEAR
- Clear coat for exposed concrete
- Transparent waterproofing for tiles
- Waterproofing natural stone
- Protecting wood and metal
RAINCARE PU CLEAR is a single-component, ready-to-use, transparent polyurethane blended waterproof coating. Being clear, it leaves the original appearance, colour and texture of the substrate completely unchanged — making it ideal wherever a visible protective coat would compromise aesthetics. Single-component, self-curing, cold-curing. Resistant to water, dilute acids, oils, fungi and micro-organisms. Service temperature: -20°C to +80°C. For metal, concrete, wood, asbestos, stone and plaster — for exterior vertical walls, roofs, terraces, metal and asbestos structures, and concrete or metallic floors requiring abrasion resistance.
Specifications
Figures are controlled laboratory results. Actual site performance varies with substrate, temperature, humidity, application method and workmanship — please confirm the current product datasheet before specification.
Where to use RAINCARE PU CLEAR: clear PU waterproof coating that keeps the original look
RAINCARE PU CLEAR is a clear PU waterproof coating that is single-component and ready to use, with no mixing. It dries to a smooth, glossy, transparent film, so the original appearance, colour and texture of the surface stay unchanged. This transparent polyurethane coating is applied by brush, roller or airless spray on a completely dry surface.
Exterior Vertical Walls
Waterproofs walls without changing their colour or texture.
Roofs & Terraces
Clear film at 35–40 sq.ft per litre per coat on concrete.
Metal & Steel Structures
Covers 50–60 sq.ft per litre per coat on steel.
Wood Surfaces
Protects wood while its original look stays visible.
Asbestos Sheets
Brushed, rolled or sprayed on clean, fully dry sheets.
Concrete & Metallic Floors (Abrasion Resistant)
Tough, glossy, abrasion-resistant film for concrete or metallic floors.
Natural Stone
Stays invisible, so the stone keeps its colour and texture.
Top Coat Protection over Existing Coatings
Clear protective top coat laid over an existing coating.
Used as transparent waterproofing for tiles, stone or exposed concrete, each coat dries to 40–45 microns. Surface dry time is 30–40 minutes, recoat is after 10–12 hours at 30°C, hard dry is 24 hours and full cure takes a minimum of 72 hours. Service temperature is -20°C to +80°C. Packs are 1, 5 and 20 Ltrs. As a clear coat for wood and metal it needs ventilation, so do not apply inside tanks or rooms, and never on damp surfaces.
Armstrong Chemicals supplies RAINCARE PU CLEAR to sites across Telangana, Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, including Hyderabad, Vijayawada, Bengaluru, Kochi and Chennai.
Waterproof Protection. Zero Colour Change.
A clear, glossy, single-component polyurethane coating that leaves metal, concrete, wood and asbestos exactly as it found them — transparent by design, resistant to water, acids, oils, fungi and abrasion, across a service range of -20°C to +80°C.
Get a QuoteWhen Waterproof Means Visible
Every standard waterproof coating applies a colour — white, grey, cream — that changes the surface appearance permanently. On exposed concrete, natural stone, wood, metal or asbestos, a coloured coat changes what the surface looks like.
The RAINCARE PU CLEAR Advantage
A transparent polyurethane coat that protects against water, acids, oils, fungi and abrasion while leaving the original surface colour and texture completely unchanged. Waterproofing that is invisible by design.
-20°C to +80°C Service Temperature
The widest service temperature range of any Armstrong waterproof coating — from sub-zero cold storage environments to high-temperature metal roofs and industrial surfaces in tropical climates.
Multi-Substrate — One Clear Coat
Bonds strongly to cement concrete, cement plaster, mild steel, wood, stone and asbestos — the broadest substrate range of any single-component coating in the Armstrong range, in one ready-to-use product.
Clear by Design
Waterproof protection that preserves the original appearance of every surface.
Transparent — Original Look Preserved
Dries to a clear, smooth, glossy finish — the original colour, texture and character of concrete, metal, wood or stone remains fully visible through the coating.
-20°C to +80°C Service Range
The widest service temperature range of any Armstrong waterproof coating — performing across sub-zero cold storage and high-temperature industrial metal surfaces simultaneously.
4 Substrate Types — 1 Product
Bonds strongly to concrete, mild steel, wood and asbestos — one ready-to-use product covering every surface type that requires transparent waterproof protection.
Acid, Oil, Fungi & Abrasion Resistant
Resistant to water, dilute acids, oils, chemical solutions, fungi and micro-organisms — and abrasion-resistant enough for use on concrete and metallic floors.
How to Use
Ensure the surface is completely dry — RAINCARE PU CLEAR must not be applied on damp or moist surfaces (blister formation will occur)
Clean thoroughly by wire brushing and water washing — remove dust, loose particles, oils, grease, mould release agents and old coatings
For new concrete or plaster: allow minimum 28 days water curing before application
For heavily dirty or acid-etched surfaces: wash with 15–20% hydrochloric acid, wire brush thoroughly, then wash with water until neutralised; allow to dry completely
Apply RAINCARE PU CLEAR by brush, roller or airless spray
Allow 10–12 hours between coats at 30°C
Ensure adequate ventilation during application — do not apply inside tanks or rooms
Do not apply when substrate temperature is below 10°C
Hard dry: 24 hours · Full cure: minimum 72 hours
Clean tools with water immediately after use
Once the container is opened, consume the product immediately
Applicable Areas
Packing & Storage
Available in 1, 5 & 20 Litre packs. Shelf life 12 months at -10°C to +35°C in original unopened containers. Consume immediately once opened — do not store partially used containers.
Key Constraints
Not for damp or moist surfaces — blister formation will occur. Do not apply inside tanks or rooms — adequate ventilation mandatory. Do not apply below 10°C substrate temperature. Some people are sensitive to resins, hardeners and solvents — wear gloves and goggles during application.
Clear by Design
RAINCARE PU CLEAR dries completely transparent — the original colour, texture and appearance of the substrate remains visible through the coating. No white film, no colour change, no loss of natural surface character.
