ELASTOCRYL 900 is a two component liquid-applied, cementitious acrylic waterproof elastomeric material with outstanding adhesion to various substrates.
ELASTOCRYL 900 is a blend of ordinary portland cement, graded silica sand and additives (part A, powder) belong with one container high performance acrylic emulsion (part B, liquid). ELASTOCRYL 900 complies with ASTM C957-1998.

ELASTOCRYL 900 waterproof coating for interior and exterior concrete and masonry.It covers existing hairline cracks and bridges hairline cracking caused by structure movement.
ELASTOCRYL 900 is a waterproof concrete and masonry building for exteriors. It is recommended for exterior facades, walls, floors, swimming pools, internal lining of water tanks, and flat and corrugated roofs.
ELASTOCRYL 900 is ideal for waterproofing concrete roof, wood, glass, asbestos, tiles,metal surface and masonry building exteriors.
ELASTOCRYL 900 acts as an effective waterproofing membrane in concrete water storage tanks, retaining walls, swimming pools, kitchens and bathrooms.

  • Low cost.
  • Moves with crack bridge > 2 mm.
  • High bonding with cement-based surfaces.
  • Non-toxic and suitable for potable water tank.
  • Fiber re-enforcement will provide hard and tough flexible membrane.
  • Available in white and grey
  • Hard wearing – durable.
  • High abrasion resistance.
  • Good resistance to gases and moisture.
  • Applicable to apply on floor and walls.
  • Captures water from the structure.

All surfaces should be clean, dry and free from dust and other contaminants. A dry sponge should be used to remove water on wet surfaces. Treat oil or grease contamination with degreaser followed by water or steam cleaning.
New and unpainted surfaces must be structurally sound, clean, dry, fully cured. Free from dust, curing agents, form release agents,efflorescence, scale, or other foreign materials.
All cracks larger than hairline shall be considered as moving and must be repaired with RENDACOAT FC cementitious concrete repair. Remove all unsound concrete. Patches shall be flush with the surrounding surface and shall match the texture of existing surfaces. Angle filet and corners should be arranged by using RENDAGROUT HB and kept to full cure before applying ELASTOCRYL 900

ELASTOCRYL 900 liquid should be poured into plastic pails. Add two liters sweet water then mix with slow speed drill. Add the powder gradually to the liquid and mix for 3 minutes until a homogenous slary liquid forms.

ELASTOCRYL 900 may be applied by roller or airless sprayer. A brush may also be used for touch-up and edging work or for areas unsuitable for spray application. Airless spraying and rolling are the most effective methods for obtaining a uniform film build.
Always apply in two coats in order to avoid pinholes. Allow 6 – 8 hours drying time inbetween coats. Due to its consistency nature, it is possible to build an appreciable thickness without sagging by using a trowel.
Best results are obtained by flush clean water to concrete wall as a primer coat. The second coat shall be applied in a direction perpendicular to the first coat after it dries and preferably in a different color to get high toughness in order to imbed the
tensile fiber glass in between.
Areas with permanent contact with water (e.g, water reservoir) shall be dry for atleast 7 days after application before filled with water.
COVERAGE
Actual coverage may vary depending on surface profile, porosity and method of application. ELASTOCRYL 900 is applied at a rate of 14 – 16 m2/pack at 1.0 mm WFT thickness.
CLEANING
Tools and equipments should be cleaned immediately by using sweet water.
