Master the Art of Fibreglass Roofing with Our Expert Guide
Step-by-Step Guide to Fibreglassing Your Roof
Step 1
Step 1: Prepare the Roof Surface – Ensure the roof is clean and dry before starting.
Step 2
Step 2: Mix Resin and Hardener – Carefully measure and mix the resin with the hardener, maintaining the correct ratio for optimal results.
Step 3
Step 3: Apply the Fibreglass Mat – Lay the fibreglass mat onto the roof surface and saturate it with the resin mixture.
Understanding the Process
1
Prepare the Surface
Preparation and Materials
- Learn the Basics: Familiarize yourself with fiberglassing techniques using our resources or online tutorials.
- Gather Materials: Ensure you have all necessary materials, including resin, glass mat, roller, paddle roller, and protective gear.
2
Apply the Resin
Laying the Laminate
- Unroll the Mat: Begin at the lowest point of the roof and carefully unroll the mat, aligning it to avoid overhangs.
- Apply Resin: Use the 7″ polyester roller to apply one-third of the catalyzed resin to the board.
3
Lay the Fibreglass Mat
Carefully position the fibreglass mat onto the resin-coated area, smoothing it out to avoid air bubbles.
- Wet Out the Mat: Unroll the mat onto the resin-coated board and wet it out with two-thirds of the resin, using the roller in strips.
- Consolidate: Allow the resin to soak into the mat for 2-3 minutes. Then, use the paddle roller to consolidate the laminate, ensuring even coverage and eliminating pinholes.

it's crucial to maintain a 3:1 resin-to-glass ratio.
To ensure optimal performance and durability, it’s crucial to maintain a 3:1 resin-to-glass ratio.
Here’s how to achieve this:
- Prepare the Surface: Ensure the board is clean and free of debris.
- Apply Resin to the Board:
- Dip the 7″ polyester roller into the catalyzed base resin.
- Remove excess resin by gently tapping the roller against the bucket.
- Apply 3 full rollerfuls of resin to a 1-square-meter area of the board. This will provide the necessary one-third of resin for the ratio.
- Wet Out the Mat:
- Unroll the mat onto the resin-coated board.
- Work in 7″ strips, applying 1 full rollerful of resin to the center of each strip.
- Roll the resin outward to the end of the strip, then back over the entire length.
- Continue this process across the entire 1-square-meter area.
- Repeat for subsequent 1-square-meter sections, always maintaining the 3:1 ratio.
By following these steps, you’ll effectively achieve the desired resin-to-glass ratio for your laminate roof.
Consolidating the Laminate
Consolidation is a crucial step to ensure the laminate is properly bonded and protected.
Follow these steps:
- Allow Soaking Time: Let the resin soak into the mat for 2-3 minutes. This allows the resin to break down the emulsion binder and ensure proper adhesion.
- Feather the Edges: Use the paddle roller to gently roll back and forth along the edges of the wetted-out mat. This helps to feather the edges and create a smooth transition.
- Consolidate the Entire Surface: Roll the paddle roller over the entire wetted-out mat, ensuring at least two passes are made. This helps to distribute the resin evenly and eliminate any air pockets.
- Monitor Resin Saturation: A correctly wetted-out laminate should appear transparent with no white or opaque areas.
- Inspect for Imperfections: Carefully inspect the laminate for pinholes, which can lead to porosity and water penetration. Pay particular attention to overlaps and ensure they are properly feathered in.
Remember:
- In colder weather, the resin may be thicker and require additional time to wet out.
- Exercise caution near the roof’s edge and in windy conditions to avoid resin spray.
By following these steps, you’ll ensure a strong and durable laminate roof.
