Damage to the laminate manifests in four ways. These consist of tears, holes (or punctures), crushed core laminate or delamination.

At this stage it is important to identify the type of resin used during original construction. Any repair carried out to an original roof is a secondary bond. If the roof is constructed using an Epoxy Resin, then it is important to also use Epoxy Resin during the repair process.

After completing the prep work it is time to fill the damaged zones. Mix resin and catalyst until the texture and viscosity is that of mayonnaise. Apply this mixture into the repair area, filling above the repair horizon. Then allow to cure.

Once cured, the repair area can be sanded down until level and blended. Now it is time to move on to the next stage, which is applying laminate.
Laminating the damaged areas

Once again, examine the size of the repair area, then pre-cut the glass fibre material into different sized layers. Usually two layers are sufficient. Apply one layer slightly smaller than the repair zone (or sanded zone), then a second which is large enough to cover the entire area that is sanded.
