Application

• For priming substrates before each use of weber.floor floor mortars and floors
• On absorbent and non-absorbent substrates
• Recommended for difficult surfaces
• Also for priming substrates under other floor underlays

properties

• Increases mortar adhesion to the substrate
• Prevents dehydration of mortars before setting
• Protects against blistering
• Improves the flow of floor mortars

Substrate preparation

weber.floor 4716 has very good adhesion to dry, strong, compact, contamination-free concrete (cast and prefabricated), ceramic, stone, wooden, screed in cement, terrazzo, steel, etc. The substrate should be cleaned mechanically, e.g. by shot blasting and thoroughly vacuum. Substrates greasy with oils or greases degrease with a suitable preparation and / or burn. Weak or soft substrates (e.g. bituminous) should be removed.
