Application Situation

Liquid Sulphur is a secondary product in the fuel products manufacture. After several processes, clean solid Sulphur is sold on in the market.

Application Method

The application was carried out in accordance with Belzona System Leaflets TCC-9 and TCC-15. Damaged and loose concrete was removed. Then we used the blasting process. We made sure the surface of the concrete is clean/dry/free of any loose contaminants and then we used to condition the surface with your 4981. The eroded vertical surface of the tank was rebuilt with Belzona 4181. In the end Belzona 1392 has been applied.
