WATER PRIMER EPX

Two-component, water-based epoxy primer for in depth consolidation of absorbent substrates. It has a great penetrating ability and forms barrier to rising moisture of up to 4%. When applied prior to the use of cement-based coatings such as self-levelling compounds like PLANO 120 S/F or microcement coatings PLANOCOLOR MICROCEMENT, PLANOCOLOR GRANULATES S 500 silica sand must be scattered on the final coat, while it is still fresh.

WATER PRIMER EPX can be used:

o as primer for reinforcing concrete substrates and screeds

o for normal to high absorbent substrates

o as adhesive primer for smoothing and laying mortars

o as primer for NOVAMIX decorative coatings

• Form: liquid

• Working time:

o 1 hour ≈ 30°C

o 2 hours ≈ 23°C

o 2,5 hours ≈ 10°C

• Walkability:

o 4 hours > 25°C

o ≈ 8 hours > 12°C

• Application temperature: from +10°C up to +30°C

Substrate preparation:

The surface to which WATER PRIMER EPX is to be applied, should be clean, dry and free from dust. The substrate must be insulated and not subject to rising moisture. The maximum permissible moisture content of the surface must not exceed 4%. The application surface temperature (caution not ambient temperature) should be between + 10°C and + 30°C.

Preparation of the mix:

Before mixing, stir component A separately with a low speed electric mixer. Then add component B completely to component A. Mixing of the two components is done for about 2-3 minutes with an electric mixer at low speed. It is important to stir both the walls and the bottom of the container so that the catalyst goes everywhere evenly. Allow the mix to rest for a few minutes. The end of the workability is not recognized by the increase in viscosity, so it is necessary to apply the material within the specified time.

Application of the mix:

Apply the mix in a continuous (non-interruptive) layer using a suitable varnish roller or brush. In any case, ensure that the material penetrates well in the treated surface. If necessary, apply a second coat. If it is to follow the application of cementitious products after the adhesive coating has dried, it is considered necessary to spray on the still wet surface quartz sand such as S 500.

Recommendations:

• Do not apply when the temperature is lower than +10°C and the relative humidity of the atmosphere exceeds 80%, or when there is a possibility of rain and wet weather

• Do not apply on substrates with rising moisture

• Apply an additional coat if more than 24 hours pass before coating

• The two components of WATER PRIMER EPX are in a premeasured proportion so never mix partially the two components

• The end of the workability is not recognized by the increase in viscosity, so it is necessary to apply the material within the specified time

• Do not apply WATER PRIMNER EPX upon old varnishes and dusty or dirty surfaces

• Always use appropriate and clean tools

• The application has to be performed by a professional user

Cleaning:

Buckets, tools, coatings etc. can be cleaned with water as long as the mix is still fresh. Once dried cleaning can be done only by mechanical means.
