Natural Weathering Test for Sealant: Real Sun, Real Rain, Month by Month

Accelerated laboratory testing compresses years into weeks; natural weathering does the opposite and takes its time. This video covers outdoor exposure of sealant samples to real sun and real rain, tracked month by month — the slow evidence behind a claim that a facade sealant will not chalk, crack or discolour.

For exterior and facade applications, ask any supplier for both halves of the story: the accelerated results, and the outdoor exposure programme that supports them. A datasheet with only the first half is a datasheet with an unfinished sentence.

Key Points

  • Sealant samples exposed to real outdoor sun and rain, not artificial ageing alone
  • Progress recorded month by month over an extended period
  • Relevant to facade, curtain wall and exterior joint applications
  • Exposure records available to distributors and specifiers on request
