Tikkurila Fontefloor EP Primer is a two-component water-borne epoxy lacquer.

Fontefloor EP Primer seals the concrete surface and provides adhesion to all Temafloor coatings and screeds, and Fontefloor paints. It can be also used for patching cracks and holes in concrete.

Fontefloor EP Primer dries in 6 hours for overcoating. This varnish is also used for priming of damp concrete with relative humidity over 97% prior to Fontefloor EP 100 epoxy paint.

For industrial and professional use only.

Features & Benefits

• Seals the concrete surface and confirms adhesion prior to Temafloor coatings and screeds and Fontefloor paints
• Suitable for priming of damp concrete (relative humidity of the concrete over 97%) surfaces prior to Fontefloor EP 100 epoxy paint
• Good water vapour permeability
• Can be used for patching cracks and holes in concrete
• Used for dust binding and priming of untreated concrete floors
• The M1 classification for low-emitting building materials has been granted by the Finnish Building Information Foundation RTS
• Uses include:
  • Public and commercial buildings
  • Production plants and chemical industry
  • Warehouses
  • Sports arenas
  • Pharmaceutical premises
  • Food processing industry
  • Hospitals and clinics

Technical Data

• Volume Solids: Approx. 66%
• Specific Gravity: 1.1 kg / l (mixed).
• Pot Life (23℃):Approx. 40 min after mixing (50 % thinned).
• Reaction to fire: B_FL -s1

Practical Coverage:

Coverage on concrete floors is on average:

• Priming - 5–7 m²/l

Practical coverage depends on the porosity and evenness of the substrate and on the application method.

Drying Time (23℃):

• Dust dry after 5 hours
• Recoatable after 6 hours
• Fully cured after 7 days

Drying and recoating times are related to the film thickness, temperature, the relative humidity of the air and ventilation.

Mixing Ratio:

• Base - 1.5 parts by volume - Fontefloor EP Primer
• Hardener - 1 part by volume - 008 4571

Surface Preparation

New Concrete

• Remove laitance by power grinding or hydrochloric acid etching.
• Choose the method best suited for the premises.
• After grinding remove dust carefully with a vacuum cleaner.
• Hydrochloric acid etching is carried out with diluted hydrochloric acid (1 part concentrated hydrochloric acid, 4 parts water).
• Rinse with plenty of water.
• Dry the surface.

Old Concrete

• Remove all grease, oil, chemicals and other impurities by Maalipesu detergent.
• Remove old peeling paint layer by grinding.
• Choose the method best suited for the premises.
• Clean out pot-holes removing all loose friable material.
• Open cracks with e.g. an abrasive tool.
• Remove loose material and dust.

Recommended Primers

• Fontefloor EP Primer

The primer should be thinned by 30–50%. If necessary, repeat priming to get a non-porous surface. A porous priming coat will result in holes and air bubbles in the finished coating.

Recommended Topcoats

• Fontefloor EP Clear
• Fontefloor EP 100 epoxy

Application Conditions

• The temperature of the ambient air, surface or coating should not fall below +15ºC during application or drying.
• Relative humidity of air should not exceed 80%.

Note! There is a natural tendency of this coating to chalk, discolor or yellow unevenly. It is recommended to use polyurethane topcoat when there are high aesthetical requirements on colour appearance.

Mixing Components

• First stir base and hardener separately.
• Mix the correct proportions of base and hardener thoroughly (approx. 3 minutes to get homogenous mixture) by using a low speed industrial hand drill with a paddle.
• Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface, weaken the properties of the coating and risk the success of the application.

Application

Priming:

Prime using 30–50% thinned Fontefloor EP Primer. Always add the water needed to a ready mixture and stir thoroughly. Pour the mixture onto the floor, apply with a rubber trowel and level with a roller.

If necessary, repeat priming to get a non-porous surface. A porous priming coat will result in holes and air bubbles in the finished coating.

Patching:

Patch pot-holes and cracks with a mixture of unthinned Fontefloor EP Primer and dry, clean sand. Mixing ratio e.g. 1 part by volume of varnish mixture and 1–2 parts by volume of sand of grain size 0.1–0.6 mm. Sand the patched areas before overcoating, if necessary.

Note! Concrete surface should always be primed before patching.

Topcoating:

• Overcoating should be done within 6 hrs after priming.
• If the primed surface is not overcoated within 48 hrs, it should be abraded.
• Add the remaining mixture to the next batch of the product, do not scrape it out of the container onto the floor.

Note: Fontefloor EP Primer adheres also to wet concrete. If there is constant moisture rising from the concrete and Fontefloor EP Primer is topcoated with a non-breathing coating or screed, there is a risk of failure between the primer and topcoat.

Add the remaining mixture to the next batch of the product, do not scrape it out of the container onto the floor.

Thinner/Cleaning

Thinner

Water.

Cleaning Of Equipment

Equipment should be cleaned immediately after use with water before the paint has dried.

VOC

VOC 2004/42/EC (cat A/j) 140 g/l (2010)

Fontefloor EP Primer: max. VOC < 140 g/l
