The Paint Stripper is a neutral, water-based coating stripper formulation used to remove the underlying primer coating once the removal of the PropOne Clear Coat is complete. Both products are free of toxic, carcinogenic and corrosive solvents such as Dichloromethane (DCM), NMP and phenol.

Paint Stripper may soften or even dissolve some plastics. Please check beforehand by testing a small area and seeing if plastic if affected. Do not allow coating of Silicone Remover to dry out during use if conditions are hot or windy. This can be achieved by encasing or wrapping the surface in clingfilm or enclosing individual propeller blades on plastic bags fixed in place with elastic bands or cable ties. This product can be used elsewhere as a general-purpose silicone remover, to remove silicone residues <0.5 mm thickness. PropOne Paint Stripper can also be used to soften and aid removal of other coatings used in the marine sector such as antifouling, 2-pack epoxy, decorative alkyds, enamels and clear coat varnishes. It will not strip high gloss PU topsides coats or gelcoat. Method Statement – PropOne Silicone Remover and Paint Stripper Silicone Remover 1. 2. 3. 4. 5. 6. 7. 8.

In hot and/or windy conditions drying out of the Silicone Remover can be prevented by covering the treated area with cling-wrap Do not allow the Silicone Remover to come in contact with water. This will deactivate the product. Leave Silicone Remover in contact with coating to be stripped for 2-3 hours or until softened. Remove with a stiff nylon or wire brush, scrubbing in a circular motion. Wipe off any remaining residue with a xylene or toluene-soaked cloth. If unsoftened silicone clearcoat remains after scraping, apply second coat of stripper. When all silicone residue has been removed, proceed to apply the Paint Stripper.

Apply Paint Stripper approximately 2mm thick using a brush or roller. Take care on vertical or overhanging surfaces, as stripper may drip. Leave the Paint Stripper in contact with the coating for at least 15 minutes or until primer coat has softened. Paint Stripper remains effective while in a wet state.
