For anything resin, West System is king
This Micro Sphere Blend is a pure white, hollow glass bubble-based, low density filler designed for filling and fairing of fibreglass.
When the filler is mixed with West System epoxy at a ratio of 10% to 25% by weight, it creates a smooth creamy paste for filling and fairing over glass fibre repairs. It's a cost-effective way of getting your mixture just right, to ensure your boat hull or general fibreglass project is as strong as the day you bought it.
- Very easy to sand
- Designed for tough conditions
- Easily hidden behind paint or polyester gelcoat
- This product quantity suits 1L of epoxy resin.
Note: This filler must be protected by further coats of epoxy if used below the waterline.
