Spectraseal LS is a one-component, solvent-based UV light stable moisture curing polyurethane sealer. It provides a high-gloss finish that accentuates the colour of surfaces while delivering exceptional stain resistance and a durable wear layer.
With an abrasion resistance of only 21mg weight loss (compared to 100mg for standard primers), it is ideal for high-traffic areas. Three coats are recommended for heavily trafficked surfaces. Can be thinned with xylene for porous substrates.
Once opened, the product must be used within 2 days. Coverage rate is approximately 5 sqm per litre. Manufactured at our ISO 9001 certified facility in Wollaston, Northamptonshire.
