Plaster Gypsum

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.

For manual mixing, add to the mixing container 10 - 12 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. 

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.

For smooth concrete substrates, use a sandblast or wire brush to clean and prepare the surface. Optionally, and for more adhesion, add 0.5 liters of Vetonit Bond 2 to the mixing water. 

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

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.

Let the Plaster Gypsum fully dry. Do not use water. Apply paints & coatings once the plaster dries out completely, generally after 7 days.

Clean all tools immediately after nishing by water. Clean hardened materials mechanically.
