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.
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.
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
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.
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.
Packaging & Coverage
Stated consumption data are for general guidance.
Actual value depends on the nature of substrate,
method of application & wastages.
Shelf Life & Storage
The original sealed bag of Plaster Gypsum has a shelf
life of 12 months, provided it is stored clear of ground
in a dry, shaded place, at temperatures between 5oC –
35oC.
Health & Safety
Plaster Gypsum is alkaline; therefore, avoid direct
contact with eyes or skin. It is recommended to use
protective gloves and goggles during application.
Any skin contact should be wash with soap & water. In
case of eye irritation, immediately wash with a copious
amount of clean cold water. Seek medical advice.
Plaster Gypsum is non-flammable.
