Description :

FORMSEAL PU 1K is a clear, penetrative, solvent based one part polyurethane sealer specifically developed for the con-crete industry to seal formwork ply and special timber features. It is principally used to extend the life of formwork panels or wood features and to standardise absorbency in the timber. It is also capable of being applied to damp timber unlike many competitor 2 part solvent borne systems.

Advantages :

• Greatly extends mould and formwork life by sealing of the surface
• wood fibres to provide an abrasion and chemically resistant coating.
• Standardises surface absorption therefore vastly reduces the effect of hydration variation staining appearing on the concrete.
• Vastly reduces the possibility of Hemicellulose (wood sugar) attack which produces a very dusty concrete surface and possibly dark staining.
• Single pack, solvent based product for easy application by brush or roller.
• Resistant to formwork chemical release agents, mould oils, retarders and alkali cement once cured.
• Can be applied successfully to damp timber that is surface dry.
• Will not impair the bond of paints, plasters, coatings, etc when used with the correct type of release system.
