Intergrain Enviropro Timberseal Alcohol Based is a high performance alcohol based sealer that is suitable for most timber types. Timberseal Alcohol Based enhances the natural colour of interior timber and parquetry floors, while helping to reduce the risk of tannin bleed. Timberseal Alcohol Based is lower in odour when compared to traditional solvent based sealers, and is made of >80% sustainably sourced solvents. Timberseal Alcohol Based is designed to minimise grain raise. We recommend sanding the 1st topcoat, and not sanding the sealer.
