Do GRP roofs crack?

The main reason for a GRP roof cracking is due to the roof being poorly installed. During the summer months, heat causes the fibreglass roof to heat up during the day and expand. And the movement which occurs during this process of thermal expansion can cause the GRP roof to crack open.

How long does GRP take to cure?

between 20 to 30 minutes
Ideally, it is best to aim for a curing time of between 20 to 30 minutes. Never use less than 1% or more than 4% catalyst. Never underestimate the effect of temperature. Resins will not cure at or below freezing and will always cure much quicker in direct sunlight.

Can you fibreglass in the rain?

Water will contaminate the resin and prevent it from curing. If it rains at any point after the resins or topcoats have started to change from a liquid to a solid, although not ideal, it should be OK. Any rain falling will settle on top and not mix so the resins should still complete their cure.

Why does curing concrete make the concrete crack?

While curing concrete will go a long way toward strengthening the finished project, many concrete slabs will crack anyway—despite all precautions—due to concrete shrinkage as water is used up in the hydration process as well as temperature fluctuations.

What kind of sheeting do you use for concrete curing?

Either polyethylene sheeting that’s at least 4mm thick or a concrete curing insulating blanket—both available from DIY stores—are good for this task. Wet the concrete thoroughly, and then cover it with the sheeting of your choice, using bricks, rocks, or other heavy items to hold it in place.

How long does it take to cur a concrete slab?

Three days of pond curing does the work of seven days of moist curing, and without daily attention—just be sure the water level remains above the concrete slab. If it drops, you’ll need to refill a little. This technique isn’t for everyone, though, because it takes quite a bit of soil to form berms around a big concrete slab.
