Tikkurila Temafloor 400 is a two-component solvent-free epoxy varnish. An excellent product for dust binding and priming of new and old concrete floors, especially where solventless and odourless products are needed. The lacquer can be used for patching when filled with sand.

This lacquer is a main component of Temafloor 4000 grinding screed. Temafloor 400 also can be apply on the top of Temafloor coatings and screeds. It can be used with mosaic flakes as a top lacquer to increase anti-slip properties

Features & Benefits

• Used as a binder for Temafloor 4000 troweling screed and epoxy concrete.
• Used also as a topcoat on top of Temafloor coatings and screeds.
• Filled with sand also suitable for patching of concrete floors.
• Suitable for dust binding and priming of new and old concrete floors under Temafloor coatings.

Technical Data

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

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.

If cementitious screed is used, check compatibility with the levelling screed manufacturer.

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%.
• Sunlight will affect on the shade and the gloss of the varnish in the long run.

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. 2 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 about 30% thinned Temafloor 400 epoxy varnish.
• Pour the varnish onto the floor and apply as much as is needed to impregnate the concrete surface.
• 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.
• Subsequent treatment can be carried out after 2 hours using "wet-on-wet" technique.

Patching:

• Patch pot-holes and cracks with a mixture of unthinned Temafloor 400 epoxy varnish 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.
