Fontefloor EP Primer - Epoxy primer

Fontefloor EP Primer
DESCRIPTION A two-component water-borne epoxy primer.

Used for dust binding and priming of untreated concrete floors.

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.

Can be used for patching cracks and holes in concrete.
Recommended uses Concrete floor.

Features • Good water vapour permeability.
• The M1 classification for low-emitting building materials has been granted by the Finnish Building Information Foundation RTS.
Gloss groups Semi-gloss
Building material emission class M1

Coverage on concrete floors is on the average:


Priming  5–7 m2/l


Practical coverage depends on the porosity and evenness of the substrate and on the application method.
Thinner Water
Mixing ratio Base 1.5 parts by volume 008 4570
Hardener 1 part by volume 008 4571
Pot-life (+23°C) Approx. 40 min after mixing (50% thinned).
Drying time at 23°C and 50% relative air humidity

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.
Solids volume approx. 66%.
Density 1.1 kg / l (mixed).
Product code Base 008 4570 and hardener 008 4571

Application conditions The relative humidity of the concrete should not exceed 97%. 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%.
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 floor.

Old concrete
Remove all grease, oil, chemicals and other impurities by Maalipesu detergent. Remove old peeling paint layer by grinding. Clean out pot-holes removing all loose friable material. Open cracks with e.g. an abrasive tool. Remove loose material and dust.
Priming Prime using 30–50% thinned Fontefloor EP Primer. 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.
Finishing Overcoating should be done within 6 hrs after priming. If the primed surface is not overcoated within 48 hrs, it should be abraded.Pour the mixture onto the floor and apply it with a trowel and level with a roller.

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.

Mixing of 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.
Cleaning of tools Water. Equipment should be cleaned immediately after use before the paint has dried.
