Surfboard Laminating Resin is low exotherm and thixotropic. It creates lightweight parts with UV stability. Surfboard laminating resin has a fast wet out and quick cure. Cures at room temperature. It cures with a surface tack to allow for multiple layers without sanding between them.

Popular Uses

-Surfboards

-Yacht/ Boat Construction

-Spray up process

-Hand lay up application

-DIY Fiberglass Applications

-Where a clear laminate is necessary

Needed Supplies (this will vary depending on your project):

• Surfboard Laminating Resin
• MEKP (methyl ethyl ketone peroxide) is required
• Brushes/rollers/spreader or squeegee
• Safety clothing- gloves, mask, eye protection
• Mixing/ measuring cups
• Stir sticks or paint paddle
• Cleaning supplies such as acetone and rags

Preparation

-Work in a well-ventilated area. Surfboard laminating resin gives off strong fumes that you want to avoid inhaling.

-Wear proper safety clothing including gloves and a face mask

-Make sure the resin, room and the surface you are working on are heated up to room temperature.  The ideal temperature to work in is between 70-85 degrees.

-Make sure the surface is clean and free from contaminates before getting started. The surface may need to be roughed up before applying resin.

Application

-Use a graduated mixing cup to measure the resin. Smaller batches are recommended.

-MEKP can be used between 1% and 2% by volume of resin but we recommend 1.25% to 1.75% depending on how long of a pot life and working time is desired. The more MEKP that is used, the shorter the pot life/ working time will be. The less MEKP that is used, the more pot life/ working time there will be. You can find our MEKP catalyst quantity chart HERE.

-Mix resin and hardener thoroughly for at least one minute to ensure uniform consistency.

-Apply immediately to fiberglass or surface

-Depending on your project, you can use brushes, fiberglass rollers, spreaders or squeegees to apply the resin.

-Gel time will vary from around 10-20 minutes depending on how much MEKP hardener was added and the room temperature

-Continue adding layers if needed. On the final layer, use Surfboard Finishing Resin for a hard tack free cure. (If adding a gel coat after, this is not necessary. Use a waxed gel coat for the final layer.)

-Cure at room temperature

Proper Handling and Storage

• Keep resin and hardener containers tightly sealed in a cool, dry place.

• Store at temperatures below 75°F to maintain shelf life (approximately six months for Surfboard Laminating Resin).

• Keep the materials away from heat sources, sunlight, and open flames.

Important Notes

-Surfboard Laminating Resin has a shelf life of around 6 months. 

-Cures with a surface tack which helps multiple layers to adhere to each other without sanding. A surface seal/wax can be added to the last layer to create a hard tack free finish.

-Do not add too much MEKP.  If too much hardener is added, the finished product can be prone to fractures or resin will become rubbery in the mixing cup.

-If you do not add enough MEKP, your laminate may never cure.

***Always try out a small test batch first.  Working with resin is more of an art than a science***
