Intumescent fire proof paint gone milky

Recommended Posts

Hi

 

my mum has a wooden chalet that has wooden ceilings and she had to paint a fire proof product on the ceilings. It’s gone milky in some places and completely white in others as if it’s an actual paint.

 

does anyone know how to reverse this whitening? Or would it be a sand back job. I think she has since realised she should have finished with a top coat that stops it going white but there we are.

reply to an old post but...  our intumescent paint was hydroscopic and irreversibly so - it went white on contact with water or humidity.

 

The misses once hung a damp towel over a coated door and that door forever had a ghostly white sheen, the supplier said that it was a one way street and sand and re-apply was the only option. Of course, we left it
