Hempel Paint Stripper For Antifoul - 2.5 Litre

Hempel’s Paint Stripper 69560 is a solvent-based paint remover supplied in a 2.5-litre pack for removing old paint and varnish from most painted or varnished surfaces. It can be applied to most coating types, including antifouling, alkyd paint, varnish, epoxy and silicone.

The product is designed for maintenance and coating-removal work where existing finishes must be stripped before surface preparation and repainting. Antifoulings, alkyd paints and varnishes normally require the shortest treatment period, while silicone and epoxy coatings require longer exposure. Old or particularly thick coating systems may need more than one treatment.

Apply Hempel’s Paint Stripper liberally by brush or roller to a dry surface. Work on manageable sections rather than treating a large area in one step. Cover the treated section with aluminium foil to reduce evaporation of the active solvents, then leave it for 30–45 minutes until the coating dissolves, softens or lifts. Scrape away the loosened coating and clean the surface with hot water and a suitable boat shampoo.

No thinner should be added. The product must be above 10°C during application and should not be applied in direct sunlight. Do not use a hot-air gun and keep the product away from flames and hot surfaces. A small test patch should always be completed first to establish the required treatment time and confirm compatibility.

Use particular caution on glass fibre and plastic surfaces because the stripper may damage some thermoplastic materials. The current Hempel Product Data Sheet does not specify a theoretical spreading rate; the quantity required will depend on the coating type, thickness, condition and whether repeat treatment is needed.

Safety: Hempel’s current UK Safety Data Sheet classifies the product as harmful if swallowed, capable of causing an allergic skin reaction and capable of causing serious eye damage. Wear protective gloves and eye or face protection, avoid breathing vapour, and consult the product label and Safety Data Sheet before use.

Frequently Asked Questions

What is Hempel’s Paint Stripper 69560 used for?
It is used to remove old paint and varnish from most painted or varnished surfaces. In marine maintenance, it can be used on coatings such as antifouling, alkyd paint, varnish, epoxy and silicone.

Can Hempel’s Paint Stripper remove antifouling?
Yes. Hempel specifically identifies antifouling as one of the coating types with the shortest treatment period. The exact result will depend on the coating type, thickness and age.

Can it remove epoxy and silicone coatings?
Hempel states that the stripper can be used on most coating types, including silicone. Silicone and epoxy normally require a longer treatment period than antifouling, alkyd paint or varnish.

How long should Hempel’s Paint Stripper be left on the surface?
The current Product Data Sheet specifies 30–45 minutes, or until the existing coating dissolves or lifts. Treatment time can vary according to the coating type and condition, so complete a small test patch first.

Why should the treated area be covered with aluminium foil?
Aluminium foil reduces excessive evaporation of the active solvents, allowing the stripper to remain in contact with the coating during the treatment period.

How is the product applied?
Apply it liberally by brush or roller to a dry surface. Treat a manageable section, cover it with aluminium foil, wait 30–45 minutes and scrape away the loosened coating.

Should Hempel’s Paint Stripper be thinned?
No. Hempel specifies no thinning for brush or roller application.

Can it be used in direct sunlight?
No. Hempel instructs users not to apply the product in direct sunlight. The product itself must be above 10°C during application.

Can it be used on glass fibre or GRP?
Use it cautiously and complete a small test patch first. Hempel warns that care is required on glass fibre and plastics and that some thermoplastic materials may be damaged.

How should the surface be cleaned after stripping?
Scrape away the loosened coating, then clean the treated surface with hot water and a suitable boat shampoo.

Will one application remove every coating layer?
Not necessarily. Hempel states that old or thick coating layers may require repeat treatment. The product is not guaranteed to remove multiple layers in one application.

How much area does a 2.5-litre can cover?
Hempel does not publish a fixed theoretical spreading rate or boat-length coverage figure for this product. Usage will vary according to the type and thickness of the existing coating, the amount applied and whether repeat treatment is required.

Can a hot-air gun be used with the paint stripper?
No. Hempel specifically states that hot-air guns must not be used. Keep the product away from flames and hot surfaces.

What protective equipment should be worn?
Wear protective gloves and eye or face protection and avoid breathing vapour. The product can cause serious eye damage and may cause an allergic skin reaction.

How should Hempel’s Paint Stripper be stored?
Keep the container tightly closed in a dry, shaded, cool and well-ventilated location, away from heat and ignition sources. The stated shelf life is 60 months at 25°C in the original unopened container.
