PU360 Moisture Suppressant

Claire McComb — Fri, 19 Sep 2025 11:01:26 +0000

Low-emission polyurethane primer – a one-component fast-drying polyurethane primer designed for priming substrates before the application of polyurethane and hybrid parquet adhesives. It can also be used as a means to isolate residual moisture in substrates. Quick-drying and odourless, this PU360 Moisture Suppressant contains no solvents or water, binds dust and facilitates the application of parquet adhesives. Ideal for priming of absorbent and less absorbent substrates commonly found in construction prior to application of polyurethane (PU) and hybrid parquet adhesives. When applied twice, it provides a moisture barrier on cement and concrete substrates – in cases where residual moisture is up to a maximum of 5% according to the CM method.

• Pre-Mixed Polyurethane Primer
• Single Part
• Up To 95% RH 2 Coat System
• Re-Coat in 30 Minutes

• Suitable For Underfloor Heating
• Low VOC – EC1 Plus
• No Primer Required

Packaging:
11KG

Larprime EU (EU Primer) is a universal two pack epoxy primer for use with both resin and cement-based systems. It provides high strength bonding of self-leveling compounds, repair mortars, epoxy screeds, mortars and coatings to a variety of substrates.

Larprime EU acts as an adhesive membrane and will improve the chemical, water and vapour permeability resistance of surfaces. It may also be used as a surface sealer for hardening screeds and concretes. Larprime EU is the bonding agent in the HDS resin screed system.

• Excellent adhesion
• Monolithic bond qualities
• Long open time
• Absorbs and transmits high stresses
• Outstanding adhesion

Packaging:
1kg and 5kg packs

Coverage:
4-5m2/kg (dependent upon surface texture and porosity)
