Very low-emission, two-component epoxy resin primer that can be used as a:

• barrier against capillary rise of moisture or residual moisture in unheated cement screeds and concrete floors without limitation of the maximum permissible residual moisture
• barrier against excessive moisture in heated screeds with a maximum residual moisture of 6% CM / KRH 98% relative humidity
• plasticizer barrier for old substrates and mastic asphalt before the direct bonding of parquet with elastic parquet adhesives
• protecton of moisture-sensitive substrates such as firmly adhering residues of adhesives and levelling compounds, prefabricated screeds made of plasterboards/fiberboards, wooden substrates, magnesia screeds and magnesium oxychloride screeds
• Suitable as a strengthener for highly absorbent and not sufficiently stable or dusting substrates.
• binder for producing epoxy resin mortars and screeds in combination with THOMSIT QS 10/QS 20 quartz sand
• bonding bridge "wet-on-wet" when connecting new screeds to existing surfaces.

Well-proven on difficult substrates and as adhesion promoter on natural stone and tile floors, metals, mastic asphalt screeds etc., also when expecting high loads and stresses. THOMSIT R 755 is not a waterproofing product according to DIN 18533 and DIN 18534.

THOMSIT R 755 has been approved and certified as a marine equipment item according to the EU Marine Equipment Directive (MED), issued and monitored by the certification body DNV GL, modules B and D.
