Kollerdur MO330LS is the only UV-stable solvent-based sealer in the Spectrum range, incorporating a UV stabiliser to prevent yellowing. It provides a high-gloss, stain-resistant wear layer suitable for demanding commercial environments including sports halls, bowling alleys, offices, and public buildings.
Apply at 5 sqm per litre per coat for optimal results. The product can be thinned with xylene for use on porous substrates where deeper penetration is required. Multi-coat application is recommended, with up to 3 coats for high-traffic areas to build a durable, protective layer.
The overcoat window runs from touch dry to a maximum of 24 hours. As a flammable xylene solution, appropriate ventilation and PPE are essential during application. Manufactured at our ISO 9001 certified facility in Wollaston, Northamptonshire.
