Processing information
Consumption:
Mixing proportion (A-component : B-component): 2:1
200 - 300 g/m2 per layer
The quantity is based on practical application by rolling with a roller on a smooth surface under optimal conditions. Factors such as surface porosity, temperature, humidity, application method, processing can change the consumption quantities
Surface Preparation - porous surfaces:
Thorough preparation of the surface is essential for an optimum result and a long lifespan
The surface must be dry and free of dust and grease
All loose parts must be carefully removed with a grinder
Old, loose coatings, greases, oils or organic substances must be removed
Smoothen possible surface irregularities, remove loose parts and (grinding) dust
Non-porous surfaces:
Clean/degrease surfaces with BERNERseal FS Cleaner and Thinner
Grind the surface
Clean/degrease again with BERNERseal FS Cleaner and Thinner
Application:
Mix both components thoroughly with a mechanical mixer for 3-5 minutes
Pour the mixture into a clean container and stir again for 1 minute
By pouring, you prevent that unmixed components from the edge of the container can be applied with a brush
Leave the mixture to react (stand) for 3-5 minutes
Adjust to the required consistency by adding 15-25% fresh water
Apply the finished mixture with a roller or brush until the surface is completely covered
After 6-12 hrs (not later than 24 hrs) and as long as the primer is still slightly tacky, apply the BERNERseal FS Sealant
Low temperatures may delay curing
High humidity may affect the coating properties
Note: In case of fragile or highly absorbent substrates (e.g. lightweight concrete, certain cement mortars), it is recommended to apply two layers of the BERNERseal FS Universal Primer (keep in mind the application time 45-50 min)
Advice
Do not apply BERNERseal FS Universal Primer if the outside/ surface temperature is less than +10°C
Do not wash the surface with water
Metal ball blaster can damage the concrete surface. This can have a negative influence on the adhesion
The BERNERseal FS system is not set to be anti-slip
The compressive strength of the substrate should be at least 25 MPa, the adhesion at least 1.5 MPa
The substrate moisture should be max. 5%
New concrete structures must dry for at least 28 days
Due to the large number of different materials, deviations are always possible, therefore we cannot guarantee the accuracy of our information in all cases
Considering the different object requirements and the most varied conditions, the user should always check the suitability for the given purpose
We therefore recommend that you always carry out your own adhesion tests before coating
