Hensel Hensotherm 820 KS is a thin-film water-based fire protection coating for interior concrete. It improves the fire-resistance time of pre-stressed concrete hollow ceilings up to120 minutes, reinforced concrete beams and supports up to 150 minutes, and concrete flat slab ceilings and reinforced concrete ribbed slab ceilings up to 240 minutes.
Forms a heat-insulating carbon foam barrier in the event of fire - prevents concrete structural elements from heating up and flaking off the steel reinforcement – Patent No. 2686391
Tested in compliance with the European standard EN 13381-3:2015
Warringtonfire EWCL Certificate No. ME 5119
Very well suited for Minergie-(A-/P-) Eco / Corresponds to Priority 1 of Eco-BKP
Easy to process, no loads on surrounding structure, maintenance free
External and in-house monitoring/building material approval no. Z-19.11-2196
Hensel Hensotherm 820 KS is a thin-film water-based fire protection coating for interior concrete. It improves the fire-resistance time of pre-stressed concrete hollow ceilings up to120 minutes, reinforced concrete beams and supports up to 150 minutes, and concrete flat slab ceilings and reinforced concrete ribbed slab ceilings up to 240 minutes.
In the event of fire, Hensel Hensotherm 820 KS forms a heat-insulating barrier of carbon foam and thus prevents the concrete structural elements from heating up and the concrete from flaking off the steel reinforcement – patented under European Patent No. 2686391. Hensotherm 820 KS greatly delays the build-up of heat in concrete. At temperatures over 330°C, concrete and steel reinforcements expand at different rates.
It is tested in compliance with the European standard EN 13381-3:2015, analogous to prEN 13381-3:2012, and is approved to Warringtonfire EWCL Certificate No. ME 5119.
Hensel Hensotherm 820 KS is easy to use, puts no load on the surrounding structure and is maintenance free.
This product is a 'Hensel Green Product' with low VOC (< 6g/l), an A+ VOC emission class, LEED confirmation and is AgBB tested. It is a product very well suited for Minergie-(A-/P-) Eco low energy consumption buildings and corresponds to Priority 1 of Eco-BKP.

Suspensions/Installations
The installation of suspensions, threaded rods, bolts etc. is possible up to a diameter of ≤ 20mm
Other supporting points may not exceed a diameter of ≤ 25mm
If 1 suspension/installation component piece per m² is not exceeded, compensation measures are not necessary and possible heat penetration in the event of fire is negligible
Beton-Carbonsperre must be fully dry before applying Hensel Hensotherm 820 KS - subject to a positive fingernail test
Under the optimal conditions, a wet film thickness up to 1,500µm thick can be applied in one operation
Hensel Hensotop WB top coat offers the possibility of coloured design and protection against moisture - it should be applied when surfaces are exposed to environmental influences
Do not apply the top coat before Hensotherm 820 KS is fully dried. At the earliest after 24 hours and after a positive fingernail test
