Protex wax spray 500 ml

Protex wax spray offers innovative protection for painted furniture. It was also developed to make walls painted with Venice lime paint and Volterra lime plaster more water-repellent. 

Protex is easy to use. Shake the bottle well and spray Protex on a lint-free cloth. Use the cloth to apply it to the painted surface. Usually, just one coat is sufficient.
Do not spray Protex straight on the painted surface to avoid white patches appearing. 
A 500 ml spray bottle protects approximately  20 m2 of painted surfaces.
