EverFlor - Prime DP

EverFlor Prime DP is a two-part, solvent-free epoxy floor primer formulated for the stabilisation of porous and absorbent concrete. It is the preparation stage in an EverFlor floor build-up — the coat that turns an open slab into a sound, sealed substrate ready to receive a finish.

Porous concrete is the most common cause of a disappointing floor coating. Prime DP is a 100% solids formulation, so everything you apply stays in and on the floor and nothing is lost to evaporation. It penetrates the surface and cures within it, consolidating the top layer of the concrete rather than bridging over it. The result is a substrate that no longer draws the finish coat into itself.

Supplied as a 5kg two-pack unit. Mix the two components by weight, apply one coat over normal porous concrete, then overcoat with your chosen EverFlor floor finish once the priming coat has hardened. As a reactive epoxy it has a defined working window once the activator goes in, so set the area out and mix only when you are ready to apply.

Recommended areas of use

• Porous concrete floors
• Absorbent concrete substrates requiring stabilisation before coating
• As the priming stage of an EverFlor floor coating build-up

Features

• Solvent-free two-pack epoxy at 100% solids, so nothing flashes off as solvent
• Penetrates and consolidates the top layer of the slab rather than forming a surface film
• Seals absorbency so the finish coat cures with even appearance and full adhesion
• Ready to use straight from the tin — no thinning required
• One coat covers normal porous concrete
• Applies by medium pile roller, cut in with a brush
• Foot traffic after 8 hours at 20°C, so the finish coat can follow the same day or the next
• VOC content below 30 g/l
• Suitable for interior and exterior concrete

Good to know

The substrate must be sound, clean and dry before priming. Floors must be prepared correctly to ensure good adhesion — this is the principal limitation of the product. Apply between 10°C and 25°C. Mix the full unit at 1.76:1 by weight (A/B) and do not split it into smaller quantities, as an inaccurate ratio can leave the primer uncured. Overcoat after 8 hours and within 48 hours at 20°C. Full cure is reached after 7 days. Store the unit in a cool, dry area between 10°C and 25°C and do not allow it to freeze. Clean tools with warm soapy water immediately after use, before the epoxy begins to harden.

SURFACE PREPARATION

The floor must be sound, clean and dry before you prime. Remove laitance, dust, oil, grease and any loose or friable material. Floors must be prepared correctly to ensure good adhesion — a primer cannot stabilise a surface it cannot reach.

Work between 10°C and 25°C, with 10°C as the minimum application temperature. Keep the unit in the same range before use.

MIXING

Prime DP is a two-component product. Mix Part A and Part B at 1.76:1 by weight. Always mix the full unit. Do not split it into smaller quantities, as an out-of-ratio mix can fail to cure.

Stir to a uniform colour and consistency, scraping the sides and base of the tin so no unmixed material is left behind. Pot life is up to 45 minutes at 20°C, so mix only when the area is set out and you are ready to apply.

APPLICATION

Apply as supplied — no thinning is required. Use a medium pile roller and work the primer into the surface of the concrete. Cut in at edges and detail with a brush. Apply one coat; this covers normal porous concrete at 3-4m² per kg, giving a wet and dry film of 220 microns.

DRYING, OVERCOATING AND CLEAN UP

At 20°C the primer is touch dry in 6 hours and takes foot traffic after 8 hours. Overcoat with your chosen EverFlor floor finish after 8 hours and within 48 hours at 20°C. Full cure is reached after 7 days.

Clean rollers, brushes and mixing tools with warm soapy water immediately after use, before the epoxy starts to harden.
