Instructions for use

Mixing

For manual mixing, add to the mixing container 11.5-13 liters of water for each 35Kg bag of Plaster Gypsum. For machine application, a water flow rate of 450 - 650 Ltr/hr is recommended. Add the powder to the water and mix with a mechanical plaster mixer or low-speed electric drill fitted with a suitable paddle for 3-4 minutes until achieving a uniform, lump-free consistency.

Leave the mixed material to stand for 5min, and briefly remix without adding water.

Blend Plaster Gypsum manually for small quantities and maintain the correct amount of powder to water. Mix for approximately 1-2 minutes until achieving a homogeneous mix.

Smooth Concrete Surfaces

Add 0.5 liters of Vetonit Bond 2 to the mixing water and adjust the water requirement accordingly for each 35kg bag. Follow the same mixing procedure as above.

Apply Spatter dash SB before applying Plaster Gypsum on smooth surfaces if Vetonit bond 2 is not used.

Use the mixed material within 30 minutes. Do not add water once the mixed plaster mortar starts to stiffen or harden.

Application

Plaster Gypsum is generally applied in a single coat. Use directly on block walls & rough surfaces. On smooth concrete surfaces, follow the above-mentioned recommendations.

Apply the mixed material using a spray machine or trowel technique to cover the desired thickness area. Lightweight leveling tools are required in conjunction with a trowel to fill in holes.

When the plaster stiffens lightly, treat the surface to a smooth level to eliminate all traces of protrusions and undulations.

Let the plaster set for about 30 min. Using a wet sponge, wipe the surface to a creamy smooth finish.

Curing

Let the Plaster Gypsum fully dry. Do not use water.

Apply paints & coatings once the plaster dries out completely, generally after 7 days.

Cleaning

Clean tools with water before the mortar hardens. After the hardening, remove the residuals mechanically.

Surface Preparation

The substrate should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc. Before Plaster Gypsum application, wet the entire surfaces with clean potable water and dry before Plaster Gypsum application.

Limitation
  • Do not mix with any additives or products unless recommended by Saveto.
  • Make sure the substrate is suitable for plaster coat application. In case of doubt, try on sample area to assess its suitability.
  • Do not apply the product at a temperature less than +5ºC.
  • During the summer season, the working area must be covered to prevent ill-effects from direct sun and excessive air-draught during the initial curing stage.
  • For further information contact our technical department.
