Removing old paint and antifouling
Removing old paint and antifouling is easy with Hempel’s Paint
Stripper, an effective solvent-based paint stripper. It can be used on most painted and varnished surfaces.
- You can estimate the time required by testing a small area first.
- Apply a generous amount of Hempel’s Paint Stripper to the dry surface with a brush or roller.
- Be careful when using the product on plastic surfaces (it may damage some thermoplastics, e.g. ABS).
- Do not work on too large an area at a time.
- After application, wait 15 – 30 minutes for the paint film to dissolve or detach. (Antifouling paints, alkyd paints and varnishes react the fastest, while silicone and epoxy take longer to dissolve.)
- It is recommended to cover the treated area with aluminium foil to prevent the active ingredients from evaporating too quickly.
- Scrape off the old paint and then clean the surface with hot water and Hempel’s Boat Shampoo.
- If the paint film is old or very thick, it may be necessary to repeat the treatment to remove it.
Cleaning and degreasing
Thorough pre-treatment is a prerequisite for successful painting. The surface to be painted must be clean and grease-free.
Cleaning
Hempel’s Pre-Clean is an effective cleaner for pre-cleaning gelcoat and painted surfaces to remove fuel, oil, grease, wax and silicone. Used before painting and for deep cleaning.
• For general cleaning, use 1 part Hempel’s Pre-Clean to 20 parts water, and for more demanding cleaning, use a 1:10 ratio.
• For alkali-sensitive surfaces such as aluminium, dilute the product with water at a ratio of 1:20.
• Do not use on untreated wood that may absorb water. Hempel’s Pre-Clean is also suitable for cleaning hardened paint from brushes.
Degreasing
Remove surface dirt, especially waxes or silicone, from new gelcoat surfaces using Hempel’s Degreaser.
It cannot be used with conventional single-component painting systems, as the solvents in Hempel’s Degreaser can damage the paint film.
• Work in a well-ventilated area and use a clean, absorbent and lint-free cloth soaked in Hempel’s Degreaser.
• Clean an area of approximately 1 m² at a time by moving the cloth lengthwise. Change the cloth before treating the next section. Use protective gloves and safety glasses.
• Wipe off excess Hempel’s Degreaser from the surface with a new dry cloth.
