Polywood Armour
A UV-Resistant, Durable Polyurethane Top Coat for Floors and Wood Surfaces in Need of Strength and Protection.
PolywoodArmour, based on a polyurethane formula, creates a clear gloss/matt film upon drying, delivering an attractive and robust coating with exceptional abrasion and chemical resistance. Highly durable and UV resistant, this top coat is the ideal choice for floors and wood surfaces demanding a strong, protective finish.
ENVIRONMENTALLY FRIENDLY / NON-TOXIC / LEAD FREE / LOW VOC
8-10 m2
COVERAGE
Per litre per coat, depending
on surface porosity.
USES:
Wooden Floors, Tables, Countertops, Shelving, Cabinetry, Panelling, Furniture, Doors & Frames, Decorative Wooden Items, etc.
SURFACE POROSITY TEST
Ensure that the surface is free from dust, dirt, grease, oil and or solvents. Check that the surface is sufficiently porous by doing a porosity test.
- Drop a droplet of water onto the surface and time how long it takes to absorb. If the droplet has been absorbed within 20 – 25 seconds, the surface is suffciently porous as the surface porosity would be 6% or greater.
- If the water droplet takes 25-45 seconds to be absorbed, it is recommended that the first coat be diluted with 50% clean water and the second coat undiluted.
- If the water droplet does not absorb within 45 seconds, the surface is not sufficiently porous. For concrete surfaces – An acid wash can be done to increase the porosity by applying a mixture of 1 part pool acid to 9 parts water. Pour the mixture onto the surface and leave for 1 hour. Wash the acid off using water, neutralise, wash off again.
- Redo the porosity test.
- Ensure all acid residue has been removed, before applying the product.
APPLICATION
STEP 01:
Ensure that the surface is entirely free of dust, dirt, oil, grease, stains and solvents. Ensure the surface is absorbent.
STEP 02:
Use a brush, sponge brush or roller or spray gun to apply. Do not apply in direct sunlight. For best results apply 2 thin, even coats. Allow 3 hours between coats. Full cure may take up to 3 days depending on ambient temperature and humidity conditions.
STEP 03:
Clean GripSeal applicators with clean water directly after application.
