Pull Seal
Pullseal is a lightweight fire-resistant spray plaster. The composition includes additives to improve the use and adhesion. Vermiculite spray plasters are lightweight and have very good insulating and fire-resistant properties.
Pullseal can be used for fire-resistant covering of concrete and steel structures. Vermiculite spray plasters can also be used for rear insulation of boilers. Pullseal 800 can be used for fire-resistant covering of structures, steel and equipment in the petrochemical process industry.

Using Pullseal
The spray plaster should be applied to a dry foundation (fat-free and dirt-free) in equal layers of at most 20mm. The spray surface should preferably be finished with a fine spray structure. Pullseal may not be used if the steel surface or air temperature is above 32ºC, without consulting Pull. Pullseal can be used when air temperature or underground temperature > 2ºC and increasing, but may not be used when air temperature or underground temperature is lower than 4ºC and falling.
Pullseal product specifications
Pullseal must be protected against extreme weather conditions during and after application until the initial hardening has taken place. Pullseal does not cause corrosion of steel. However, in a petrochemical environment, we recommend treating steel with a durable primer or galvanizing the steel before applying Pullseal.
Pullseal delivery range
The material is packaged in 25kg plastic bags. For large quantities, 25 bags are packed on pallets with sealing foil.
