How long does it take for Fibrecoat to become watertight?
How long does it take for Fibrecoat to become watertight? I live at the top end of Scotland and want a system that I can get down quickly to avoid any sudden downpours.
Will Fibrecoat bond to GRP Roofing trims
I have a roof that needs covering and was originally going to use a standard GRP system but having seen Fibrecoat I would like to use this. My question is will Fibrecoat bond to the GRP roofing trims?
Can I use Fibrecoat without the Glassfibre?
I have a project to do that involves coating a concrete roof which is around 50 square metres and in good condition. I want to know if I can use the Fibrecoat system without the fibreglass as I don't need the reinforcement.
Does the PU Activator make the surface waterproof?
Just looking through your website on Fibrecoat and want to know if I applied the PU activator, would it make the surface waterproof or would I have to apply the Fibrecoat resin system?
Breaking it down
First of all, in order to make sure your area is square, measure three metres from the corner out along one of the roof edges. From this point measure four metres across the front edge. If the diagonal line that connects these two points is five metres long then your area is square.
When measuring large roof surfaces, make it easier by breaking it down into smaller sections for example if you have an L shaped roof break the space down into two rectangles, measuring them separately and adding them together at the end.
Measure the first of these rectangles, starting with the width, followed by the length, and repeat the process on the second rectangle. Mark these measurements in your notebook.
Calculating the area
To calculate the area multiply the length by the width, so, for example, we have a roof that's 5 metres in length x 3 metres wide then the totals square metres works out at 15m2.
Once you have finished calculating all the measurements, it’s always a good idea to round up your totals just to make sure you have more than enough materials for the GRP roof you are about to take on.
