The White Isophalic Pool Resin (25kg) is a premium resin designed specifically for fibreglass swimming pool linings. Using an isophthalic-NPG polyester base, this resin offers superior water resistance, chemical durability, and UV stability, making it the preferred choice for pool relining and resurfacing projects across South Africa.
Unlike general-purpose orthophthalic resins, isophthalic resin provides longer-lasting protection, reduced maintenance, and improved performance under harsh pool conditions. It is particularly effective in environments with high chemical exposure and strong sunlight, ensuring your pool's surface remains smooth, watertight, and resilient.
This product is supplied in 25kg sealed containers and is available on a collection-only basis from our partner depots (no shipping). Orders are typically ready within 12 working days, with a notification confirming collection.

A: Isophthalic resin is tougher, more durable, and longer lasting. It costs more but saves on repairs and maintenance in the long run.
Q: Is this resin safe for DIY use?
A: No. This resin requires professional application by a qualified fibreglass pool contractor. It is not recommended for DIY projects.

A: This listing is for white resin. Top coats are available in white or blue.
Q: Can it be used with surface tissue and clear top coats?
A: Yes, for the smoothest, most durable finish, a layer of surface tissue and a protective clear top coat are highly recommended.
