Cellulose Sanding Sealer

£10.50 inc VAT

Our cellulose sanding sealer is pre-thinned down to our preferred ratio, penetrating deeply into your wood and producing a smooth surface after a few coats, over which you can apply your final finish perfectly. We’ve tried many different sanding sealers and discovered this cellulose sealer and thinners mix to be perfect for everyday, coloured and textured work. Please note this product cannot be shipped outside of the UK. Visit Stockists Page for overseas distributors.
