How To Gelcoat A Kevlar Canoe

Before going to gelcoat a kevlar canoe repair, the first task is to decide whether you need to use it to the whole body surface or a specific part of it.

However, if you follow the steps presented here describing how to Gelcoat a kevlar canoe, you will reasonably get the job done simply for kevlar canoe scratch repair too.

Step 1: Remove The Existing Gelcoats

The kevlar canoe’s surface may already have a cote of gelcoat. Use sandpapers to remove the loose gel coats. Wear gloves and rub the sandpapers over the surface. You can also use 150 grit instead of sandpaper for sanding. It will produce dust. Wear a mask to protect yourself from dust.

Step 2: Clean The Kevlar Canoe

The next step is to clean the canoe to make it dirt-free. If the canoe has any dirt left, gelcoat coating will not create a more reliable seal. To clean the canoe, you can spray and use some solution of boat cleaning.

Step 3: Wipe It With Acetone

After cleaning the canoe, wipe it with acetone to ensure there is no grease or dirt left on the canoe. Use a blow-dryer to dry the canoe. It will make a better gelcoat bond.

Step 4: Outline The Repair Area

If there are some scratches in specific areas, outline or mark the area with masking tape. Look for quality masking tape to protect the canoe surface. You should skip this step If you are to gelcoat the entire canoe rather than a part of it.

Step 5: Prepare The Gelcoat Solution

Take the appropriate color that matches your canoe. Several colors are available for kevlar canoe, such as forest green, white, orange, red, yellow, and blue. Mix up some catalysts with gelcoat to prepare a thick dissolution. A thick solution will provide a glossy finishing.

Use a paintbrush to apply gelcoat like you are painting a kevlar canoe. Give two thin coats on the canoe’s surface.  Try to apply it as early as possible after mixing the catalyst. Otherwise, the outside temperature will make it hard. Leave it to dry after applying gelcoat.

We recommend you get in touch with the kevlar coat manufacturer for any essential tips. Each gelcoat manufacturer produces different gel coats with different ingredients that may have specific instructions for gel coat repair canoe.
