Hi,I am site manager in a school and need to paint over our suspended ceiling tiles ,some having water marks on . can you give me products that are suitable.
Assuming the suspended ceiling tiles are clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Zinsser AllCoat Interior (Solvent-Based).
This can be applied by brush, roller, pad or airless spray and is available in many RAL and BS colours.
