Vetotherm Plaster

The substrate should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc.
Before Vetotherm Plaster, wet the entire surface with clean potable water; the surface should look damp at the time of the Vetotherm Plaster application.
For smooth concrete surfaces, a spatter dash should be applied before the application of Vetotherm plaster.

Add to the mixing container 6 - 7.4 liters of water for each 20 Kg bag of Vetotherm Plaster or 900 - 1300 lit/hr for the plastering machine application. Add the powder to the water and mix with a mechanical plaster mixer or low-speed electric drill fitted with a suitable paddle until achieving a uniform, lump-free consistency.
Manual mixing is allowed for small batch quantities. Mix for approximately 1 - 2 minutes until achieving a homogeneous mix.

Apply Vetotherm Plaster in a single or two coats manual or machine application to achieve the desired thickness of 25- 100 mm.
Apply the mixed material using a spray machine or hawk & trowel technique. Rod or screed to uniform thickness, not exceeding 25 mm for a single coat or 25 mm for each coat for multiple layers. Pres the first layer hard against the surface.
For the second layer, allow the first layer to set (60 - 120 min depending on weather) partially. Apply the second layer as described above.
Water spray the surface if the second layer is carried out the next day.
To ensure proper water demand for this job, it is a best practice is to do the application on a small area with the desired thickness to check the adhesion to substrate and the cohesiveness of the material.

The best way to cure Vetotherm Plaster is by spraying water evenly on the applied material surfaces every 12 hrs for a minimum of 3 days. During hot & dry conditions, allow curing for a minimum of 5 days; It will help obtain high mechanical strengths.

Clean all tools immediately after finishing with water. Clean hardened materials mechanically.
