It is often impossible to know the type and build depth of anti-fouling before coatings are removed. It is essential to apply a test patch to an area typical of the surface to be stripped to ensure the results will be satisfactory. This will also indicate the dwell time required and thickness of paste to be applied. 

Apply evenly with Airless spray, brush or trowel working into crevices, including on wooden hulls where planks overlap. Ensure raised edges and corners are covered well. Then apply a second coat to the final tested thickness. Finally, lay on the poultice with printing facing outwards, gently rubbing to exclude trapped air bubbles. Work in manageable areas which can be removed within the time scale indicated by the test patch. Peelaway® Marine should not be left on longer than 48 hours when used on GRP/Gel coat substrates. 

Slide scraper into paste and paint, keeping the paint, paste and cover together as much as possible. Take care not to gouge/scratch the gel coat. Steam cleaning or pressure washing may aid removal of residues. Once all the old anti-fouling paint has been removed, any remaining residues of Peelaway® Marine must be cleaned/washed away. Allow the cleaned surface to dry thoroughly before re-coating.
