Floor coatings for concrete surfaces

TEKNOFLOOR L42 EPOXY COATING SYSTEM
TEKNOFLOOR 100F solvent-based two-component coating 

Applications
Industrial facilities, garages, warehouses

Properties 

• Strong surface, excellent mechanical durability 
• Ease of cleaning 
• Withstanding of chemical stresses well 
• Ease and simplicity of application

Application conditions
The surface to be coated must be dry. New concrete must be at least four weeks old. During application and drying, the air, surface, and coating temperatures must be above 10°C and the relative air humidity below 80%.

Drying time
The product can withstand light traffic after 12 hours if the coating, air, and surface temperatures during coating and drying are 23 °C.

Amount to be used
TEKNOFLOOR 100F: approx. 8 L for 20 m², priming and one finishing coating
TEKNOSOLV 9506: approx. 3 L

Stages
1) Surface pre-treatment performed mechanically or by acid etching

Mechanical treatment
Dense laitance is removed from the concrete surface via grinding, sandblasting, or shotblasting. After pre-treatment, the cement dust and other impurities are carefully removed by, for example, vacuuming.

Acid etching
Etching is done with the RENSA ETCHING agent (diluted with water 1:1) or diluted hydrochloric acid (1 part acid to 4 parts water). Apply the solution over the entire surface area.

Remove the sludge with a brush. Rinse the floor thoroughly. Wait for the concrete to dry before applying the coating.

2) Priming
Mix the TEKNOFLOOR 100F components thoroughly. Dilute the mix with 20–40% TEKNOSOLV 9506. Apply the coating with a short-piled mohair roller generously so that the surface is sealed.

3) Finishing coating, 1–2 times
Finishing coats with undiluted coating are applied 6–24 hours after priming. The coating is applied generously to achieve an even, thin film. Coating is performed in a similar way to that used in priming. 

TEKNOFLOOR L40 EPOXY COATING SYSTEM
TEKNOFLOOR AQUA 110F water-based two-component coating

Applications
Basements, bathrooms, concrete floors exposed to light traffic. Suitable also for wall surfaces.

Properties

• Strong surface, excellent mechanical durability
• Ease of cleaning
• Good withstanding of chemical stresses
• Ease and simplicity of application
• Rapid drying
• Suitability also for wall surfaces

Application conditions
The product can be applied to a dry or slightly moist concrete surface. There must be no liquid water on the floor. During application and drying, the air, surface, and coating temperatures must be above 10°C and the relative air humidity below 80%.

Drying time
The product withstands walking after four hours if the coating, air, and surface temperatures during coating and drying are 23°C.

Amount to be used
TEKNOFLOOR AQUA 110F: approx. 8 L for 20 m², priming and finishing coating

Stages
1) Surface pre-treatment, mechanical or by acid etching

Mechanical treatment
Dense laitance is removed from the concrete surface via grinding, sandblasting, or shotblasting. After pre-treatment, the cement dust and other impurities are carefully removed by, for example, vacuuming.

Acid etching
Etching is done by means of the RENSA ETCHING agent (diluted with water 1:1) or diluted hydrochloric acid (1 part acid to 4 parts water). Apply the solution to the entire surface area. Remove the sludge with a brush. Rinse the floor thoroughly. Wait for liquid water to dry before applying the coating.

2) Priming Mix the TEKNOFLOOR AQUA 110F components thoroughly. Dilute the mix with 5–10% water. Apply the coating with a short-piled mohair roller generously so that the surface is sealed.

3) Finishing coating
A finishing coat with undiluted coating is applied 4–12 hours after priming. The coating is applied generously to achieve an even, thin film. Coating is performed in a similar manner to that used in priming.

Note!
The product must be used within 1.5 hours from mixing. Older mixtures must not be used.

TEKNOFLOOR L44 EPOXY COATING SYSTEM
TEKNOFLOOR 500F solvent-free, self-levelling two-component coating

Applications
Industrial facilities, garages, business facilities, repair shops, and butcheries with strong mechanical stresses.

Properties

• Strong surface, excellent mechanical durability
• Ease of cleaning
• Good withstanding of chemical stresses
• Self-levelling on horizontal surfaces

Application conditions
The surface to be coated must be dry. New concrete must be at least four weeks old. During application and drying, the air, surface, and coating temperatures must be above 10 °C and the relative air humidity below 80%.

Drying time
The product withstands light traffic after 16 hours if the coating, air, and surface temperatures during coating and drying are 23°C.

Amount to be used
TEKNOFLOOR PRIMER 310F: approx. 4 L for 20 m², priming
TEKNOSOLV 9506: approx. 3 L
TEKNOFLOOR 500F: 10 L for 20 m2, coating of 0.5 mm

Stages
1) Surface pre-treatment performed mechanically or by acid etching

Mechanical treatment
Dense laitance is removed from the concrete surface through grinding, sandblasting, or shot-blasting. After pre treatment, the cement dust and other impurities are carefully removed through, for example, vacuuming.

Acid etching
Etching is done with the RENSA ETCHING agent (diluted with water 1:1) or diluted hydrochloric acid (1 part acid to 4 parts water). Apply the solution to the entire surface area. Remove the sludge with a brush. Rinse the floor thoroughly. Wait for the concrete to dry before applying the coating.

2) Priming lacquering
Mix the TEKNOFLOOR PRIMER 310F epoxy lacquer components thoroughly. Dilute the mix with 30% TEKNOSOLV 9506. Apply the lacquer with a short-piled mohair roller generously so that the concrete surface is sealed. If the coated surface is moist, TEKNOFLOOR PRIMER 306F-01 epoxy lacquer may be used in priming.

3) Coating
The coating is applied 6–24 hours after priming, depending on the temperature. The base and hardener components are thoroughly mixed. It is recommended that a slowly rotating drilling machine equipped with a stirrer be used for mixing the components. The coating is applied by means of a steel float with 0.5 mm notches, which produces the recommended film thickness. The surface is smoothed down with a short-piled mohair roller. The coating can also be applied with a short-piled mohair roller producing a film thickness of 0.2–0.3 mm.
