Mastic Type for Sky light

[Richard_374377620]

Hi,

After 15 years my sky light needs replacing, as do a few other grills on the caravan. What is the best type of mastic to use for sealing these i.e. are ones from DIY stores OK or are there better/caravan specific brands I should be using?

Thanks

Richie

Best is a non setting type, IDL99 is good, or use strip mastic.

Do not use any of the silicone sealants like B&Q as the roof does flex and will break the seal, allowing water to penetrate.
