Gypsum protective spray - 50 ml

Gypsum pieces should be sprayed three times with this liquid.

Allow 1 hour between treatments to give enough time for drying of the previous one. 

Advantages of usage: 

• It hardens the surface of the plaster. 
• Higher durability. 
• Less scratchable
• The paintability of the surface increases as the colour is less absorbed into the gypsum.
