~1.9 kg/l

Contact Sika® Technical Services for specific information.

Dry heat up to approx. +100°C

Components A : B

Sika® Thinner E+B
If necessary, max. 5% Sika® Thinner E+B may be added to adjust the viscosity.

Min. +10°C

Max. 85 %

Max. 80 % in containers

Beware of condensation!
The substrate must be at least 3°C above dew point to reduce the risk of condensation or blooming on the floor finish.
Note: Low temperatures and high humidity conditions increase the probability of blooming.

Max. 4% (CM-measurment)

Waiting time at + 20°C, for overcoating with itself:

In case of longer waiting times the surface must be activated by sweep blasting.

Drying time at + 20°C

Final drying time

Full mechanical and chemical resistance after 7 days at + 20°C.

Theoretical material-consumption/coverage without loss for medium dry film thickness of:

The concrete surface areas to be coated must meet recognised building standards, i.e. be solid, load-bearing and free from contaminants detrimental to adhesion. Pull-off adhesion strength in accordance with DIN 1048 should be > 1.5 N/mm² on average with the lowest reading no less than 1.0 N/mm². For areas subject to heavy mechanical loading, the average value should be > 2.0 N/mm² and the lowest reading no less than 1.5 N/mm². Apply suitable compatible undercoats and observe recommended overcoating intervals.

Stir component A and B very thoroughly using an electric mixer (start slowly, then increase up to approx. 300 rpm). Add stirred component B carefully and mix both components very thoroughly (including sides and bottom of the container). Mix for at least 3 minutes until a homogeneous mixture is achieved. Fill mixed material into clean container and mix again shortly as described above. During mixing and handling of the materials always wear protective goggles, suitable gloves and other protective clothings.

The method of application has a major effect on achieving uniform thickness and appearance. Spray application will give the best results. The indicated dry film thickness is easily achieved by airless spray. Adding solvents reduces the sag resistance and the dry film thickness. In case of application by roller or brush, additional applications may become necessary to achieve the required coating thickness, depending on type of construction, site conditions, colour shade etc. Prior to major coating operations a test application on site may be useful to ensure the selected application method will provide the requested results.

By brush or roller:

• Dry film thickness of approx. 150 μm per layer is achievable
• Possibly an additional layer may become necessary to achieve the total dry film thickness

Airless-spraying:

• Efficient airless equipment
• Pressure min. 180 bar
• Remove sieves
• Nozzle size ≥ 0.38 mm (≥ 0.015 inch)
• Spraying angle approx. 50°
• Diameter of hoses min. 10 mm (⅜ inch), hose at spray gun approx. 2 m, min. 6 mm (¼ inch)
• Temperature of material min. + 15°C

Sika® Permacor®-3326 EG H is a chemical resistant rigid coating product providing good wet scrub resistance. It can be cleaned by washing with soft brushes or high-pressure water jetting, using water with or without mild alkaline detergents.
