Product Properties

Low viscosity, ensures secure adhesion of subsequent coatings or sealings
Dense pore closure prevents air bubbles from rising from the substrate into the top layers
Moisture barrier, requires two coats until residual moisture is 7 CM in the substrate for cement screeds on underfloor heating, and 5 CM when used as a primer before applying floor leveling compounds with subsequent laying of textiles, elastic coverings, or parquet
Solvent-free according to TRGS 610, environmentally friendly and safe for the user, no emissions from solvents, no fire or explosion hazard
Very low emissions, GEV EMICODE EC 1 R

Application Areas

For interior and exterior use
For walls and floors
As a primer for PCI sealings and coatings on cementitious substrates, cast asphalt screeds, ceramic coverings, synthetic resin coatings, and wood substrates
As a primer for building interiors before applying floor leveling compounds, also suitable for subsequent parquet bonding on concrete, cement, calcium sulfate, and magnesite screeds
Cast asphalt screeds, ceramic coverings, and synthetic resin coatings
Wood substrates
Substrates with adhesive residues from dispersions, reactive resins, water-soluble adhesives such as sulfite release adhesives, and bituminous adhesives
As a leveling or fine smoothing compound with quartz sand mixture
As a binder for the production of epoxy resin screeds, repair mortars, and drainage mortars
Suitable for use on ships, complies with Marine Equipment Directive MED 9698

Substrate Preparation

The substrate must be dry, solid, clean, and free of grease and other adhesion impairing layers
Concrete and screeds may only be abraded with a wooden board or felt disc, not scraped with a steel trowel
Glazed or curved surfaces should be roughened by grinding, sandblasting, or shot blasting (e.g., Blastrac)
The required strength of the substrate depends on the subsequent sealings or coatings
Cracks must be repaired before priming with PCI Repament or PCI Novoment M1 plus in combination with PCI Repaht
Existing cracks should be sealed with PCI Epoxigrund Rapid or other suitable epoxy resins
If necessary, determine concrete moisture content with a CM device, maximum 4%
When using PCI Epoxigrund 390 or Rapid as a primer before applying floor leveling compounds, PCI Epoxigrund 390 or Rapid can be used as a moisture barrier up to 7 CM residual moisture in cement screeds on underfloor heating, requiring two coats

Processing of PCI Epoxigrund 390 and PCI Epoxigrund Rapid

Wear protective gloves and safety glasses
Mixing
Remove the caps from both components and add the entire hardener component to the base component
Use suitable stirring or mixing tools, e.g., from Collomix, attached to a slow-running, variable-speed drill (approx. 300 rpm), mix intensively for at least 3 minutes
For 1 kg packages, mix with a wooden or metal spatula
Transfer the mixed material to a new container, scrape off residues from the container rim and bottom into the mixture, and remix

Priming for Sealings

Apply section-wise onto the pretreated substrate with a brush, roller, or roller brush, full-surface coverage
Immediately after application, sprinkle with dry quartz sand (0.3 to 0.8 mm, max. 500 g)

Priming for Coatings

Apply section-wise with a brush or roller onto the pretreated substrate, full-surface coverage
Immediately after application, sprinkle with dry quartz sand (0.3 to 0.8 mm, approx. 1 kg/m²)
After the primer has dried, sweep off loose quartz sand and vacuum
Work further at least 8 hours later, or 3 hours after applying PCI Epoxigrund Rapid
If a moisture barrier is desired, apply PCI Epoxigrund 390 or Rapid twice: first coat without quartz sand, let dry (~8 or 3 hours), then apply a second coat
Immediately after the second coat, sprinkle with dry quartz sand (0.3 to 0.8 mm, approx. 1 kg/m²), sweep off excess sand after drying
Alternatively, instead of sandblasting, a universal primer PCI VG 2 can be applied to the last coat of PCI Epoxigrund 390 or Rapid, approx. 2 hours after application
After applying PCI VG 2, a floor leveling compound can be applied after approx. 2 hours

Use of PCI Epoxigrund Rapid as a crack filler

Mix material and fill narrow cracks (1-2 mm wide), ensuring cracks are filled to a depth of at least 5 mm or 15 times the crack width
For wide cracks, mix PCI Epoxigrund Rapid with fire-dried quartz sand (0.3 to 0.8 mm, ratio 1 part epoxy to 2 parts sand), and fill
For cracks cut perpendicular to the crack line, insert crack reinforcement clips or embedment clips into the prepared cracks
After leveling the cracks, remove excess material from the surface, then sprinkle the still fresh resin with quartz sand (0.3 to 0.8 mm, approx. 1 kg/m²), and sweep off excess after drying
