3-component, water-based primer based on polyurethane. This product is highly abrasion- resistant, very chemicals-resistant and is to be recommended for high-traffic hardwood floors. AquaSeal FireStop is suitable as primer. The final coating must be done with AquaSeal 2KPU. Giscode: W3/DD+


Special advice: for coloring purposes, Classic BaseOil can be used as alternative primer.


Application: AquaSeal FireStop is mixed as follows, shortly before use:  10 parts- AquaSeal FireStop; 2 parts- AquaSeal FireStop Add, add and mix, after that 1part- AquaSeal FireStop Hardener.

For mixing, use the BergerTool MixBox coming with the material.

Stir well immediately upon admixing the hardener. The mixture is good for 2 hours (pot life), that means although the mixture remains liquid for about one day, it shouldn’t be used any more after 2 hours because of reduced resistances of the dried lacquer film. Mix only as much material as needed. The mixture releases CO2 – so, to avoid bursting, do not close the can air-tight! The material is roller/brush-applied in 2 coats and finish coated with AquaSeal 2KPU.


Special tips: unlike conventional, solvent-based lacquers, AquaSeal should be applied in rich coats. Do not thin-roller the material.


Draying: we recommend, in order to avoid excessive swelling pressure, to roller-apply only one coat per day, so that the wood gets enough time to give off the absorbed water. In the main the lacquer can be sanded and cautiously walked on after 3-4 hrs (23°C/50% rel. humidity). In case of bad ventilation, low temperature or increased coat thickness the drying may be delayed considerably. Do not expose to wear, cover with carpets or apply care products for 8-14 days.


Consumption: depending on wood surfaces and method of working: 1coat rollared/brushed: approx 100 ml/m2 resp.approx. 10 m2/1l.


Storage/ transport: shelf life of original unopened packing (lacquer/hardener) min. 12 months for the lacquer and 12 months for the hardener, provided that material is transported and stored at a cool and dry place protected from freezing.

Store in a dry, well-ventilated place at a temperature between 15 ° C and 25 ° C. Protect from heat and direct sunlight. Keep tightly closed.
