Small scratches, chips or scrapes in your fibreglass boat can quickly turn into much bigger problems if left untreated. Moisture entering any damaged fibreglass matting beneath can cause blistering of Gelcoat surfaces which in turn leads to Gelcoat blistering; left unchecked this process of Osmosis can wreak havoc with your boat hull's integrity and lead to disastrous consequences for its future use.

Damaged Gelcoat





Gel coat gives fiberglass boats their characteristic shine, as well as protects them from water damage. However, should it become damaged due to scratches or gouges from accidental impacts, repairs must be performed quickly for optimal durability and may cost significantly. Professional assistance may be needed for such costly repairs.

Start by familiarizing yourself with your boat's gel coat finish, so as to employ proper repair techniques and find a color that closely resembles it for seamless repairs.

Once you have selected a matching gel coat color, purchase a gelcoat repair kit containing resin and catalyst. Read through and follow all instructions carefully in order to achieve an even mixture between base and catalyst. Additionally, masking tape and handheld grinder will be necessary along with acetone for cleaning and prepping surfaces.

Cracked or Scratched Gelcoat

Your boat's material makes an important impactful statement about its repairability. Aluminium boats can be repaired using aluminium welders while fibreglass vessels require specific expertise for repairs to avoid water permeating gelcoat and costing more in the long run. Inexperienced repairs could potentially cause leakage that compromises your warranty or require costly replacement costs to remedy any potential leakage issues that result.

Hairline cracks are common, and can typically be repaired using a gelcoat repair kit, while larger cracks should be addressed by calling in professional services. Deteriorated centre cores require additional attention as structural work may also be necessary to restore them.

If the scratches aren't too deep, wet sanding with coarse-grit sandpaper will suffice to eliminate them. timber machining Clean the surface thoroughly and mask off surrounding gelcoat as necessary before roughening up with medium grit sandpaper before buffing with fine grit sandpaper to achieve a sleek and shiny finish.

Cracked or Scratched Hull

Cracked boat hulls can compromise their structural integrity and require costly repairs if left untreated, but cracks in them can be repaired with marine epoxy - this material is strong and waterproof - making it ideal for boat hull repairs and easy to apply; available from most marine stores or online. In order for any repair attempt to be successful it's crucial that the correct type of epoxy be chosen to suit individual needs.

Flexing can damage fiberglass laminate or core structures, necessitating extra reinforcement. Furthermore, if the crack extends below the gelcoat layer it could indicate structural damage that requires professional repairs to address.

Blistering Hull

If you find that small blisters on the bottom of your boat have appeared recently, they might not warrant much alarm - particularly if the antifouling paint is in good condition. But if their number and size increase significantly it might be time to take action as blistering can have serious implications on resale value for older vessels. Blistering occurs due to water mixing with materials found within the laminate such as chemicals or sawdust which causes an osmotic pressure and results in bubbles on its surface; to repair these you can pop them open to drain the liquid out or grind the area down; epoxy resin provides better long term protection so this method should be employed for best results.

When blisters require grinding to repair them, they should be repaired by layering disks of fiberglass cloth to increase in diameter until reaching depressions in which to place epoxy-saturated and compressed patches of cloth.
