Description
DURAflex is a cementitious flexible waterproofing slurry — a ready-to-use blend of specially selected cements, synthetic resin dispersion and graded aggregates. It forms a seamless, flexible waterproof barrier suitable for both internal and external waterproofing jobs, including balconies, terraces, water tanks, roofs, and concrete repair surfaces.

Product Highlights
- Creates an excellent waterproof barrier — protects against water ingress under positive or negative pressure
- High bond strength — adheres strongly to concrete, plaster, masonry or screeded surfaces
- Resistant to freeze/thaw cycles and chloride ion penetration — good for harsh environments or coastal exposure
- Can be applied by brush, trowel or spray — flexible application methods
- Self-curing, non-toxic and suitable even for water tanks or potable water applications when cured properly
Technical Specifications
| Property | Specification / Details |
|---|---|
| Product Type | Cementitious flexible waterproofing slurry |
| Packaging | 5 kg kit or 15 kg kit |
| Application Methods | Brush, trowel or spray |
| Water pressure resistance | Positive up to 10 bar / Negative up to 4 bar (after full cure) |
| Typical coverage (theoretical) | ≈ 8 m² per 15 kg kit for 1 mm wet film thickness |
| Recommended dry film thickness | Minimum 1.5-2 mm (applied in two or more coats) |
| Curing time | Surface hard to touch in ~16 hours (conditions permitting); full waterproof properties in ~7 days cure. |
| Coverage rate | ≈ 2 kg/m² per mm thickness (min 2 coats recommended) |
| Pot life (after mixing) | Approximately 1 hour at 20 °C (varies with temperature) |
Application Instructions
- Ensure substrate (concrete, screed or plaster) is clean, sound, dry-cured, free of oil, grease, dust or loose particles before application.
- Pre-wet highly porous substrates slightly (substrate saturated but surface dry) before applying slurry. Do not apply if substrate is wet or water-logged.
- Mix component A (liquid) with component B (powder) thoroughly using slow-speed paddle mixer until lump-free slurry is obtained.
- Apply first coat with brush/trowel/spray to approx. 1 mm wet film thickness; allow to firm up (≈ 4–16 hours depending on temperature/humidity). Then apply second coat at right angles to first for uniform membrane.
- Protect freshly applied coats from rain, direct sun or heavy wind until cured (min 24 hours touch-dry; full cure ~7 days).
- Can be tiled over, painted or left as is (if aesthetic finish not critical). For wet areas like showers — reinforce corners with recommended membrane strip for improved waterproofing.
Suitable Applications
- Balconies, terraces, flat roofs — new or renovation waterproofing
- Concrete or masonry water tanks, reservoirs, cisterns requiring waterproof lining
- Bathrooms, showers, wet rooms (after correct treatment) for internal waterproofing under tiles
- Internal and external walls or floors requiring reliable water-tight barrier
- Repair and resurfacing of damaged concrete surfaces in buildings, bridges, parking decks, balconies — where waterproof barrier and abrasion resistance are needed
Compatibility & Limitations
- Do not apply on frozen or water-saturated surfaces. Application temperature should be between 5 °C and 40 °C.
- Not suitable for surfaces that will be subject to heavy mechanical traffic unless protected or overlaid with proper topping.
- For potable water tanks, ensure full cure time as per datasheet before filling water.
- Ensure corners, joints and penetrations (pipes, drains) are properly sealed or reinforced (e.g. with recommended mesh / membrane) to avoid leak points.
Frequently Asked Questions
DURAflex is used to create a waterproof barrier on balconies, terraces, roofs, tanks, reservoirs, bathrooms and concrete surfaces — both for new construction and renovation — protecting against water ingress, leaks and dampness.
You mix the two-part slurry (liquid + powder), then apply with brush, trowel or spray in two coats — first coat around 1 mm wet film, then second coat perpendicular for complete sealing. Proper substrate prep and curing are essential.
Yes — when applied correctly with reinforcement in corners and joints, DURAflex provides a reliable water-tight membrane suitable for shower floors, wet rooms or wet-area waterproofing under tiles.
Yes — once fully cured, DURAflex is approved for use in potable water systems, making it safe for water tanks, cisterns or containers that store water.
Suitable for concrete, screed, masonry or plaster surfaces — both horizontal (floors, slabs) and vertical (walls) — provided surface is clean, sound and free of debris or contaminants.
Yes — when cured fully, DURAflex resists positive water pressure up to 10 bar and negative pressure up to 4 bar, making it suitable for waterproofing tanks, basements or wet-area foundations.
Final dry membrane thickness should be around 1.5 - 2 mm, achieved by applying in at least two coats. This ensures reliable waterproofing and durability.
Surface becomes hard to touch after about 16 hours; full waterproof properties develop over ~7 days cure — after which tiling, finishing or water filling can commence safely.
Yes — it is versatile and can be brush-, trowel- or spray-applied, works on old or new concrete, and is especially useful for refurbishment of balconies, terraces or damaged concrete surfaces needing waterproofing.
Ensure substrate is clean, sound, and not wet or saturated. Surface must be free from grease, dust, loose particles or laitance. Apply within recommended temperature range (5 °C–40 °C) and protect from rain or heavy wind during cure.
