Use a solvent like toluene, acetone, or methyl ethyl ketone (MEK)

Removing carpet glue from an aluminium boat can be a challenging task. One effective method is to use a solvent such as toluene, acetone, or methyl ethyl ketone (MEK). These solvents can help break down the adhesive properties of the glue, making it easier to remove. Here is a step-by-step guide on how to use these solvents effectively:

Before you begin, ensure you are working in a well-ventilated area or outdoors to avoid inhaling fumes from the solvents. It is also important to wear protective gear, such as rubber gloves and eye protection, to safeguard your skin and eyes from the chemicals.

Start by applying the solvent of your choice—toluene, acetone, or MEK—to a small area of the glue with a brush or rag. Allow the solvent to soak for a few minutes, giving it time to penetrate and soften the glue. You may need to reapply the solvent a few times, as acetone, in particular, evaporates quickly.

Next, use a plastic scraper to gently lift and remove the softened glue. Be careful not to scratch or gouge the aluminium surface. If needed, use a nylon brush or stainless-steel wool to scrub away any remaining glue. You can also try using a rotary sander with 60- to 100-grit aluminium oxide paper to help remove stubborn glue residue. Remember that mechanical methods, such as sanding, will require more elbow grease and may leave scratches on the aluminium surface.

After removing the majority of the glue, use a clean rag soaked in the solvent to wipe down the area. This will help remove any remaining glue residue and ensure a clean surface. You may need to repeat the process a few times for best results.

Finally, wash the area with soap and water to remove any solvent residue. Ensure the area is thoroughly rinsed and dried before proceeding with any further treatments or coatings.

It is important to note that these solvents are powerful chemicals and should be handled with caution. Always read and follow the safety instructions on the product labels. Additionally, test the solvents on a small, inconspicuous area of your boat first to ensure they do not damage the aluminium surface.
