weberfloor 4725 EP Impregnation SE 10kg colorless

weberfloor 4725 EP Emulsion Primer SE is a factory-produced, two-component, water-emulsified epoxy resin. As an emulsion primer, it can be used on very dense substrates such as weberfloor 4610 Industry Top, in combination with weberfloor 4736 Seal WR SE or weberfloor 4774 Matt Finish SE. Suitable for indoor and outdoor applications.

• Compliant with AgBB and suitable for living spaces
• Very low viscosity
• Easy to process
• Good wetting and penetration
• Vapor permeable
• Total solid according to German Construction Chemistry testing procedure

Substrates

• Concrete, cement screed, calcium sulfate screed, magnesia screed, cast asphalt, epoxy resin coatings

Substrate preparation

• The substrate must be load-bearing, dimensionally stable, dry, and free of dust and substances that reduce adhesion
• Observe application tip: "Surface preparation procedures for liquid substrates"
• Suitable waterproofing measures must be taken in case of rising moisture
• Magnesia and anhydrite screeds are not moisture-resistant; allow for moisture equalization. Moisture from the back side can also cause bubbles, delaminations, or damage to the screed itself when applying thin coatings
• For firmly adhering old coatings, sandblast or grind until white residue appears. In case of doubt, perform a test area

Processing
Mixing:

• Components A and B are matched; pour component A completely into component B and mix with a slow-running mixer and paddle No. 2 for about 2 minutes until streak-free. Re-pot and remix. Avoid taking partial quantities if possible.
• Observe application tip: "How to properly mix and process reactive resins"
• Clean tools with water while fresh

Processing:

• Immediately after mixing, apply the material evenly in a thin, closed layer with a nylon roller in a crisscross pattern. For highly absorbent substrates, apply a second coat. Do not dilute with water!
• An even application results in a uniform gloss level and prevents shading
• Ensure good ventilation during processing and drying, i.e., air circulation. Avoid drafts
• Follow-up treatment: colorless with weberfloor 4774 Matt Finish SE or colored with weberfloor 4736 Seal WR as soon as the surface is walkable
