Hairline cracks Empty Hairline cracks

Post by Tim Richards Fri Nov 15, 2024 4:54 am

Good day.
We purchased our MH a few months ago but after giving it a thorough cleaning of the roof I've noticed an number of hairline cracks on the raised side of the roof.
Looking at the cracks it looks like impact damage.
There's no sign of damp inside the MH and the cracks are hairline. 
Does anyone have any suggestions how I might best proceed to repair these?

My initial thought it to seal them with something like Dekalin.

Your opinions would be appreciated.

We have some hairline spider cracks on the roof of our 2002 Pollensa and I treated those with Captain Tolley's Creeping Crack Cure

Assuming not a visible part of the roof, I do the Capt Tolley bit too then using a clear epoxy, a coat of that then a layer of glassfibre tissue then more epoxy to embed it.

Sand the affected area which will have the above done, then using acetone degrease it.

That'll seal it and add strength if it was impact damage.

Above assume its GRP.
