Avoid using this product in direct sunlight.

 The ideal temperature for use of this product is 77°F. Best results for this product can be obtained at temperatures between 70°F and 85°F, in a clean, dry, dust-free environment.

 It is not recommended to wet out fiberglass over 1/8 in thickness. Use of more than 1/8 may generate excessive heat. Allow layer to tack up (but not fully cure) prior to pouring next layer.

 Boatyard Polyester Resin is a non-specified resin that contains different types of polyester resins and wax. Material may cure hard and tack-free due to wax. If so, product will need to be sanded prior to adding another layer in order to promote good bonding.

 This is an economical laminating resin for repairs on boats, small parts production, autos, etc. Not recommended for use below the waterline.

 If sanding is required to apply more fiberglass, use 36, 24, or 16 grit. Low grits will create deeper scratches to make the new layer adhere better to the existing one. Be sure to clean the surface before applying another layer.

 To apply gelcoat, prep the surface with 80 grit sandpaper. To apply primer, prep the surface with 220 grit sandpaper. To apply paint, prep the surface with 320 grit sandpaper.

Directions for Use:
Step 1: Choose the appropriate volume for your project. The type of fiberglass used will determine the amount of resin needed.
Step 2: Make sure to agitate or stir the product thoroughly before use.
Step 3: Mix 1 to 2% MEKP, in resin solution thoroughly. Please refer to Catalyst Concentration Chart for quantities.
Step 4: Thinner fiberglass can easily be wet through. To thoroughly wet out heavier materials, apply resin first to one side, then flip the glass over to wet out the other side. Use paint-style rollers to distribute resin quickly.
Step 5: Roll each layer with a glass roller to remove air. The fiberglass will go completely transparent when it is adequately wet.
Step 6: Add sanding aid (Product #123833) to the final coat to allow a full cure and a tack-free surface. Refer to Sanding Aid Chart for quantities.

 It is generally not recommended to wet out fiberglass over 1/8 in thickness. Use of more than 1/8 may generate excessive heat. Allow layer to tack up, but not fully cure, prior to adding additional layers.

 General Purpose Polyester resin is a standard grade of a formulated product. This unsaturated polyester resin is designed to wet out the glass reinforcement rapidly without drainage. The rapid wetting will save time in laying up laminates.

 This is an economical resin, designed for hand lay up of boats, panels and other industrial fabrication of demanding quality.

 If sanding is required to apply more fiberglass, use 36, 24 or 16 grit. Low grits will create deeper scratches, allowing the new layer to adhere better to the existing one. Be sure to clean the surface before applying another layer.

 To apply gelcoat over the resin, prep the surface with 80 grit sandpaper. To apply primer, prep the surface with 220 grit sandpaper. To apply paint, prep the surface with 320 grit sandpaper.
