APPLICATION MATERIAL SAFETY DATA SHEET MUST BE READ BEFORE OPENING THIS PRODUCT.
The base product should be dry containing no solvent or moisture as once the Polyurethane is dry it can help trap moisture or solvent underneath which could cause the sealer to lift. Previously coated substrates should be checked for solvent resistance and compatibility in both their wet and dry states. Sound substrates need to be thoroughly sanded to provide a surface key. There should be no contaminates which could lead to loss of adhesion. For porous surfaces the first coat must be diluted to penetrate into the substrate and provide better wetting. Dilution can be up to 50/50 with xylene solvent. If there are doubts about application or appearance, test a small area first. Diluted sealer must be used immediately and not stored or returned to the original sealer. Decant the quantity of Polyurethane required for immediate use only.The original container should be resealed immediately to prevent moisture getting in. Apply Polyurethane either by brush, roller or airless spray. For spray, applications between 5% -10% solvent can be added, this will shorten the pot life. A slip resistant additive may be required particularly if the area gets wet. |
Technical Data Sheet
TOP COATING
Re-coating should be within 16-18 hours depending on conditions prevailing. If too much time is allowed for cure, adhesion can be difficult to obtain on subsequent coats. If too much time has elapsed then the first coat will have to be sanded to provide extra key before the 2ndand 3rdcoats are applied.
NOTE
Do not pour Polyurethane back into the original container. In doing so contamination in particular moisture can be included which will result in a shortened shelf life of the original material.
USAGE RATE
1 X 20Litre drum covers approximately 48 to 100m²(two coats) or as specified depending on surface texture.

LIMITATIONS
Needs moisture to cure hard.Low humidity inhibits cure. When thoroughly dry, a mist of water over the polyurethane will accelerate cure. The use of xylene as a softening agent for re-coating is essential to improve inter-coating adhesion. When resealing Polyurethane, it is advised to lightly sand the old coating to help with adhesion.
STORAGE
Recommends storage in a cool, well ventilated space away from heat sources. Keep tightly lidded. Keep away from reducing agents and strong oxidizing agents. Take precautions against static electricity discharges. See State and Federal Regulations as to storage.
SHELF LIFE
6 months in un-opened container stored as recommended. After this time product should be checked to ensure suitability for use.
DISPOSAL
Contaminated absorbent to be disposed of in a secure land fill in accordance with local bodies , state and or federal authorities.
PRECAUTIONS
After sealing, it is recommended that the sealed surface be protected from foot traffic for a minimum of 48hours. Vehicle traffic for a minimum of 72hours. Time required depends on weather conditions coating thickness etc. Therefore check suitability before allowing traffic.
