Description

Waterproofing Coating Asmacoat WP 900 20liters

GZ INDUSTRIAL SUPPLIES NIGERIA is the distributor of Water proofing chemicals in Nigeria including Asmacoat products

ASMACOAT WP 900 is a liquid applied, coal tar modified, single-component moisture- curing polyurethane coating. It is designed to form a seamless, elastomeric waterproofing membrane. When fully cured ASMACOAT WP 900 forms a permanently flexible waterproof lining to most building surfaces including reinforced concrete, block works, brick works, cement render, plaster board and fibre-reinforced cement. The properties like high elasticity, very good crack bridging and impermeability to water vapour make it capable of effectively waterproofing even in most demanding conditions.

Waterproofing Coating Asmacoat WP 900 20liters advantages:

• Single component ready for use (no mixing required).
• Excellent elasticity, allows expansion and contraction with the substrate, without cracking or becoming brittle.
• Excellent chemical resistance.
• High thermal stability which eliminates melting and flowing at high temperature. • Excellent workability.
• Excellent adhesion to wide range of construction materials.
• Provides a continuous, seamless waterproofing membrane.
• Easy to repair.

Uses:

ASMACOAT WP 900 can be used for a wide range of waterproofing applications viz. Roofs, Basements and Foundations, Tunnels and bridges, Terraces and Balconies, Car Decks, Plaza Decks, Planter Boxes, Retaining Walls, Internal Wet Areas (kitchens, bathrooms), Fountains and Pools..., etc. ASMACOAT WP 900 can also be used in sewages works and tanking applications in areas where aggressive ground water conditions prevail.

Surface Preparation:

New concrete surfaces should be fully cured. Substrate should be free from dust, oil, curing agent residues and other contaminants. Voids and honeycombs must be patched with concrete repair products. Allow the patched area to cure before applying the membrane.

All metal surfaces should be made clean of paint, oils, rust and other contaminants. Abrade to expose bright metal then wipe clean the surface prior to priming.

Normally good quality concrete substrates do not require priming. However, porous surfaces require priming. To reduce blisters caused by air entrapment on rough and porous surfaces, use ASMACOAT WP 900 thinned with 50% ASMACOAT WP SOLVENT as a primer. To join fresh applications of ASMACOAT WP 900 to those that are more than 48 hours old, apply diluted ASMACOAT WP 900with 50% ASMACOAT WP SOLVENT as a primer at the interface.

Expansion and movement joints should be sealed with ASMACO PU 90 / ASMACO PU 90 L PU Sealant. When cured, a 200 mm wide layer strip of ASMACOAT WP 900should be applied centered over all sealed joints. While the membrane is still wet, cover with a correct cut stripe of fiber mesh and press it to soak. Saturate the fiber mesh with another coat of ASMACOAT WP 900 until it is fully covered. Allow curing before applying the waterproofing membrane.

Instructions for Use:
ASMACOAT WP 900 should be applied by brush, roller, trowel or airless spray in two coats to achieve a minimum dry film thickness of 1.0 mm. The second coat should be applied at right angle to the first one once the first coat is completely dry (but before 48 hours). ASMACOAT WP 900 membrane must be cured for a minimum of 24 hours at 25 °C before placing protection.

Extended periods of exposure will require the provision of membrane to eliminate possible surface damage or to avoid contamination it is recommended to apply screed mortar bedding or protection boards. Tiling or finished flooring installations should be carried out as soon as possible after full cure of membrane is established. If protection board is used, a dust coat of cement should be used to prevent adhesion of the membrane to the boards. Where a bond with the topping is not required, a separator sheet should be used.

Do not apply tile adhesives to ASMACOAT WP 900 membrane whilst the membrane is still uncured. To provide a good key with the membrane, spread the final wet coat ofASMACOAT WP 900 with sufficient clean silica sand.

Standard Compliance: ASMACOAT WP 900 confirms to: • ASTM C836

Good resistance against acidic and alkali solutions, detergents, seawater and oils.

Consumption:

1.3 Kg/m2 per millimeter thickness.

Cleaning:
Tools and equipment used for application of ASMACOAT WP 900 should be cleaned with ASMACOAT WP SOLVENT after use.

Packaging:

The product supplied into sealed metallic container of 20 Lt.

Storage:

Keep the product in tightly closed original containers in a dry place away from direct sunlight at a temperature between +5 and 30OC. The ASMACOAT WP 900 will have 12 months shelf life if stored in original unopened container below 25OC. A thin layer of skinning is considered normal and will not affect the performance of the product.

Limitations:

Don't apply the product with imminent rain forecast, or on humid support. ASMACOAT WP 900 should not be applied on surfaces with a risk of rising dampness and should not be applied at temperature below 5 °C. The minimum application life for the opened pack is up to 48 hours if stored in closed and dry container. Water test should be run after the membrane is fully cured. For Bitumen substrates, contact the Technical Department at Anchor Allied Ltd for advice. During the peak temperature of the day in the summer season, working area should be covered to prevent direct sun effects.

Health & Safety: Wear gloves, goggles to avoid any contact with eyes and skin. In case of splashes in the eyes wash abundantly with warm water and consult a doctor.
