Top tips for using our Fibreglass Roof Kits in the Summer

Okay so we are seeing some pretty hot sunny weather at the moment in the UK. Great news for some, but can create tricky working conditions if you need to complete your Fibreglass Roof using one of our Kits.

Composite Roof Supplies will happily guide you along the way, ensuring a smooth transition from Purchase, Process, to Completion.

10 key steps:

  • Check the weather on the day you wish to commence work. Download a reliable app on your smart phone, Met office is a good one to use.

  • Check the surface temperature of your boards, a good way to do this is with a point and shoot laser temperature gauge: https://www.fibreglassroofingkits.co.uk/laser-infrared-digital-thermometer

  • Do not start Fibreglassing your Roof if the temperature is above 35°C as it will cure too quickly. Use the catalyst addition chart to ensure the correct ratios are used, 1% for each kilo is a good start.

  • Store the Resin and Topcoat in cool place.

  • Mix small amounts, ensuring you have time to empty the whole bucket.

  • Do Not apply Roofing Topcoat in direct sunshine, the wax solution will burn off before curing, this will leave a tacky surface.

  • Get an early start to avoid the heat of the day.

  • Try to arrange extra help to lay the main laminates, 1 person wetting the other consolidating is going to speed up the whole process.

  • Pre-plan as much as you can, plenty of gloves on hand, cleaning solutions to keep rollers in good condition, dry cut all your fibreglass sheets and set them aside.

  • Ensure open tins of Resin are not exposed to extreme sunshine, they are pre excelleratied and can cure with additional hardener.

Catalyst should be applied using the chart below, You will have an email from us with useful links and guides on mixing after you make your order.
