Temafloor AC502 - Solvent-free acrylic binder

Temafloor AC502
DESCRIPTION A two-component, solvent-free, elastic acrylic binder.

Suitable to be used as a self-levelling coating and as a binder of a coloured sand screed.

Suitable also for indoor asphalt floors.

Mixed with sand also suitable for patching of concrete floors.

Recommended for the floors of engineering workshops, warehouses, cold stores of food industry parking deck surfaces, loading ramps and terraces.
Recommended uses Used as a binder for Temafloor AC acrylic troweling screed.

Features Cures fast also in low temperatures.
Colour Range The colour of the screed is determined by the sand used.
Gloss groups Semi-matt

For a flat substrate:

2 mm layer: 2 litres ready for use screed / m2

6 mm layer: 6 litres ready for use screed / m2


Practical coverage depends on the evenness of the substrate.
Can sizes 200 l drum, content 200 kg.
Mixing ratio Self- levelling screeds 5–6 mm:
Temafloor AC502 30 w-%
Coloured sand Ø 0,1–0,6 mm 30 w-%
Coloured sand Ø 0,3–0,8 mm 40 w-%
Surface is fully broadcast with coloured sand Ø 0.6–1.2 mm.
Application method Priming: Temafloor AC102 Primer is applied with a roller or trowel.

Coating: Temafloor AC502 mixture is applied with serrated spatule. Screeded surface is rubbed by hand or used scattering technique.

Topcoat Temafloor AC602 Clear lacquer mixture is applied with a rubber trowel and level with a roller.

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 + 5ºC during either application or drying. Relative humidity of air should not exceed 80%.
Preparation New concrete
Remove laitance by power grinding, vacuum grit blasting 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, milling or vacuum grit blasting. 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.
Priming Prime using Temafloor AC102 acrylic primer. Pour the primer mixture onto the floor and apply by the trowel or roller as much as is needed to impregnate the concrete surface. If necessary, repeat priming to get a non-porous surface. Subsequent treatment can be carried out after 30 min.

Scatter sand of grain size 0,4–0,8 mm on the fresh primer coat to ensure the screed adhesion and prohibit gliding of the screed.
Patching Patch pot-holes and cracks with a mixture of unthinned Temafloor AC502 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 0,5–1,2 mm.

The floor can be levelled by using Temafloor AC502 and sand of grain size 0,5–1,2 mm.
Diluting Do not thin.
Screeding Pour the Temafloor AC502 mixture onto the floor. Apply by an adjustable trowel to the desired thickness. Trowel the screeded surface by hands or use broadcasting technique.
Lacquering Topcoating can be carried out after the screed has cured. Topcoating can be carried out with Temafloor AC602 Clear topcoat. Pour the varnish mixture onto the floor, spread with a rubber trowel and level with a roller.
Mixing of components Mix the correct proportions of base and hardener powder thoroughly (approx. 2 minutes) by using a hand drill with a paddle, concrete mixer or power mixer. The amount of mixture depends on the area to be coated and on the pot life of the mixture. Insufficient mixing or incorrect mixing ratio will result in uneven drying of the surface, weaken the properties of the screed and risk the success of the application.
Cleaning of tools Cleaning of equipment with Thinner 006 1400.
