Features & Benefits

• Thinned Temafloor 200 Primer penetrates well into the pores of the concrete sealing the surface and giving good adhesion for coatings and screeds
• Mixed with sand also suitable for patching of concrete floors
• Suitable for priming of new and old concrete floors prior to laying Temafloor coatings and screeds

Technical Data

• Volume Solids: Approx. 100%
• Specific Gravity: 1.1 kg / litre (mixture).
• Pot Life (23℃): About 15 minutes after mixing, on substrate.

Practical Coverage:

Coverage on concrete floors is on average:

• 1st primer coat - 4–8 m²/l
• 2nd primer coat - 6–10 m²/l

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

Mixing Ratio:

• Base - 2 parts by volume Temafloor 200 Primer
• Hardener - 1 part by volume 008 4406

Drying Time (23℃)

• Dust dry after 3 hours
• Touch dry after 5 hours
• Recoatable after 6 - 12 hours
• Light trucking</strong after 16 hours>
• Fully cured after 7 days

The drying times are for Temafloor 200 Primer thinned 30% with Thinner 006 1029.

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 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%.

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.
• Use power mixer for mixing.
• 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 Temafloor 200 Primer epoxy varnish.
• Pour the varnish mixture 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 becarried out after 2 hours using "wet-on-wet" technique.

Patching:

• Patch pot-holes and cracks with a mixture of unthinned Temafloor 200 Primer 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.

Topcoating:

• Overcoating should be done within 6–12 hrs after priming.
• If the primed surface is not overcoated within 24 hrs, it should be abraded.
• Pour the mixture onto the floor and applyit with a trowel and level with a roller.
• Note! Add the remaining mixture to the next batch of the product, do not scrape it out of the container onto the floor.
