Gypsum Plaster - AE

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

For smooth concrete substrates, apply vetonit Spatter Dash-MC at 4 - 6 mm., and cure for at least 3 days.

For manual mixing, add to the mixing container 11.5 - 13 liters of water for each 40 Kg bag of Gypsum Plaster. For machine application, a water flow rate is adjusted till mortar consistency is achieved. 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 Gypsum Plaster manually for small quantities and maintain the correct amount of powder to water. Mix for approximately 1-2 minutes until achieving a homogeneous mix.

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

Gypsum Plaster is generally applied in a single coat. 

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 Gypsum Plaster 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.
