2-K-EP Blocking primer (DPM)

• 2-component epoxy resin for blocking non-pressing residual moisture in cement screed and concrete
• For strengthening surface edge zones.
• Suitable as bonding layer on mastic asphalt, ceramic tiles, wood-based panels or as a moisture protecting layer of moisture sensitive subfloors.
• To cover fixed, water-soluble adhesive residues.
• For the production of epoxy mortars in combination with Eurocol 846 Europlan Sand/847 Europlan Sand fine.
• For blocking non-residual moisture in unheated cement screeds without limiting residual moisture.
• For indoor use only.
• Very low emission certified EMICODE EC1 Plus.
• Declared by baubook, "ecological building product".

• for blocking non-pressing residual moisture in cement screed and concrete without limitation of residual moisture,
• for strengthening surface edge zones.
• Suitable as bonding layer on mastic asphalt, ceramic tiles, wood-based panels,
• suitable as a moisture protecting layer of moisture sensitive subfloors, to cover fixed, water-soluble adhesive residues,
• for the production of epoxy mortars.

• The substrate must be pressure- and tension-resistant, free of cracks and dust, even and free of layers that reduce adhesion.
• Adhesion-reducing layers, old material residues must be removed by suitable mechanical measures in accordance with the specifications of DIN 18365/DIN 18356.
• Old fixed floors, such as ceramic tiles, terrazzo, stone floors, must be thoroughly cleaned and sanded matt after drying.
• Smoothed concrete floors, cement screeds and vacuum concrete are to be shot-blasted.
• Cracks or joints (except structural expansion joints) are to be closed with Eurocol Europlan 913 Silicate sealing compound.
• In case of defects, objections are to be reported in writing.

Before use, temper the product according to the processing conditions.

• Add comp. B to comp. A, therefore cut through the synthetic cap and bottom of component B with a screwdriver. Thereafter unlock the packaging, in this way the hardener will easily penetrate into the resin.
• Stir mechanically to a homogeneous mixture.
• Apply the mixture immediately with a lambswool roller. Avoid puddles.
• On strong porous subfloors as well as application as a DPM apply after 16 - 24 hours a second coat.
• To avoid adhesion problems of levelling compounds sprinkle the last coat always with 846 Quartzsand. As a DPM sprinkle the second coat.
• After 24 hours remove excess 846 Quartzsand with a broom or industrial vacuum cleaner.
• For sealing seams and cracks mix the product with 846 Quartzsand until the required thickness. Fill the seam or crack with the mixture and seal the seams to approx. 20 cm width with the primer and thereafter apply 063 Eurotape into the wet coat. Thereafter prime with the product and sprinkle directly with 846 Quartzsand.
• Lower temperatures < 10 °C will increase the finale bond strength significantly.

Use as reaction mortar:
By adding Eurocol 846 Europlan Sand and/or 847 Europlan Sand fine (depending on the desired layer thickness and viscosity), the product can be used to produce a reaction mortar as a levelling mortar to stable filling mortar (mixing ratio mass% 1 : 0.8 to 1 : 9 - resin : sand). The freshly applied reaction mortar must be sanded in the same way as a primer. 

It is advantageous if the produced mortar is applied to the freshly applied primer, wet-in-wet. The flanks of adjacent screeds should also be primed.

Working conditions:
Required surrounding temperature: min. 18°C.
Material and subfloor temperature: min. 15°C.
Relative humidity: 35 - 75%, recommended <65%.

Pay attention to BG Chemical information leaflet M023 “working with Polyester and epoxy resins” DGUV Information 201-062 "EP resins in the construction industry" and BGR227 work with epoxy resins.
When using as a moisture barrier, make sure there is enough ventilation at skirting and behind cupboards.
