For small projects abrasive masonry blades and gritted carbide blades will work. For larger projects a diamond gritted tooling is recommended. These tools are much more aggressive then masonry and other diamond tools which are available at your local hardware store. Carbide, high speed steel, and diamond tools such as those obtained at the hardware stores will have a very short service life when use on FRP materials.
Use a rotary saw for straight cuts, and a jig saw for circular cuts. Use even steady pressure when cutting excessive pressure may cause heat and/or ragged edges. Replace dull blades to prevent buildup.
For a small number of drilled holes you can use a carbide tipped masonry bit. For larger projects use a diamond gritted drill bits.
All cut edges must be sanded smooth and sealed. Using 80 grit paper is recommended and for best results use a high speed sanding wheel. After sanding use a sealing kit designed to be used on fiberglass.
Recommended Safety Practices
Prior to cutting Fibergrate products, take the following steps:
- Carefully read the Material Safety Data Sheet (MSDS). If you do not have a MSDS one is available upon request. Individuals with respiratory ailments should not fabricate FRP products.
- Observe common safety precautions when using cutting tools. Always wear gloves when handling Fibergrate products. Wear approved safety glasses or goggles to protect eyes and a respirator (mask) to reduce inhalation of dust. We recommend the use of a NIOSH/MSHA approved mask for dust with a permissible exposure limit (PEL) of not less than 0.1 mg/M3.
- Dust from cutting FRP products can cause skin irritation. Wear clothing to reduce dust from coming in contact with skin. If cutting produces difficulty in breathing or excessive skin irritation, stop immediately and consult a physician.
- Observe common safety precautions when using the sealing kit. Read and follow instructions for kit prior to using. Always wear safety glasses and protective clothing when working with FRP products or using a seal kit. Do not allow resin or catalyst to come in contact with skin.
