Epoxy Fillers

Product Description

Epoxy fillers to mix with epoxy resin to thicken it. A combination of microfibres and wood flour blend is often all that is required in the way of fillers.

Epoxy fillers are sold by the litre.

Glass Fairing Balloons

When mixed into epoxy, white glass balloons produce a surface that can easily be sanded to a smooth finish before painting. Mix it with epoxy to form a thick paste and apply it to any rough surfaces. After curing, the layer can be sanded smooth. The trick is to sand most of it off so that the filler is only filling the holes. For a perfect finish the cycle can be repeated several times. It is possible to paint directly onto the sanded surface.

Because glass balloons make the epoxy layer porous, they are not recommended for below the waterline.

Micro-fibres

Micro-fibres give a greater tensile strength than other fillers.

Mix microfibres with epoxy when laminating two pieces of wood together. This thickens the epoxy slightly so that it is sufficient to bridge any small gaps between the wood. It produces a white mixture.

Phenolic Micro-balloons

Unlike glass balloons, phenolic micro-balloons are not hollow, so they can be used below the waterline.

Wood Flour Blend

Wood flour blend is a strong filler that makes very strong fillets. By using in conjunction with microfibres the colour of the fillet can be adjusted to match the wood being filleted.
