Vitset 45 is a ready mixed, air setting refractory mortar in a consistency suitable for trowelling and patching. Vitset 45 forms a strong air-dried bond with all grades of refractory bricks.
Ready mixed mortar is used for setting dense refractory bricks and insulation bricks above 1400oC. It is also suitable for setting ceramic fibre blankets and boards.
Our product is extremely easy to use. It is delivered as a ready-to-use mixture and one pack is enough for patching 40 fireproof bricks. The drying time is up to 24 hours at 20°C.
Stir contents of tub thoroughly before use. There may be some liquid on the top of the material received. This liquid should never be poured away but thoroughly mixed back into the whole bucket of material before removing any for use.
All surfaces for which Vitcas Vitset is to be applied should be clean and free from grease, dust and dirt.
Apply to the areas to be joined by making sure that the joints are totally covered with a bed of Vitcas Vitset. The recommended joint thickness is 3-5mm.
Do not mix any other material with Vitset.
Thoroughly clean tools immediately with water after use and replace the lid on any unused material.
Drying and hardening will be helped by the application of gentle heat as soon as the work is completed. The setting time is 24 hours at 20°C (increasing temperature will reduce the setting time).
