## Description

U-POL isopon GL//D Fastglas Glass Fibre Kit, S Size

Review: Complete kit - Everything you need is included in the kit. Perfect for my repair requirements (cracked bathtub).
Review: Used 2 of these packs to repair a fibreglass pond. I’d never fibreglassed before but actually enjoyed it and found it rewarding to do it myself. The kit made it easy. I gave it 2 coats and 3 on the worst of the cracks. There was a piece at the edge I needed to build up and reshape which was challenging but I managed it effectively using another off cut of fibreglass and a piece of plastic. Make sure you rub the area down first and wipe clean. Then dab the brush- don’t swipe too much or the material can pull apart when the mixture starts to set quickly. Left it a couple of days and then washed and rinsed the pond out before installing. It works a treat. No leaks. Happy plants and fish. Good price of kit also.

*by P***7 on 12 July 2024*

A really good product purchased to repair 2 quite large holes in my metal wheel barrow. The kit contained plenty of glass fibre, adhesive and hardener to do the job and I have a good amount left over for other jobs. My barrow no longer has holes! Great little kit. As an added bonus the smell took me back to the 1970s as I used a similar product in a poor attempt to fill the holes in my rusty shed of a car! Happy days.....great product. Thanks.
