Premix Plaster
Premix Plaster
Dudhi Premix Plaster is a polymer modified premixed cement based plaster. It is convenient, easy to use, strong and binds better to its substrate. It provides an even surface on which tiling can be done faster & efficiently. Dudhi Premix Plaster is specially formulated using graded sand to impart compactness to the plaster. It also contains special polymers which reduces re- bonding losses, thereby i increasing the productivity of the labour and has water-retaining component which reduces the curing requirement of the plaster, when compared to conventional method. It is also available in ‘Spray Plaster Machine Application’ variant.

Precaution
- Dudhi Premix plaster is non-toxic and non-hazardous.
- Use goggles, dust mask, hand gloves, helmet and nose mask while doing any type of plastering work.
- Incase of contact with eyes of dry mix, immediately wash with plenty of clean water with clean hand
and seek medical advice. - After finishing of work, wash hands with soap.
Do’s & Dont’s
- Never add extra water once mix has set to make it thin.
- Do not throw dry material after plastering for smooth surface.
- Throw plaster on wall forcibly for good adhesion.
- Plaster should be cut through to the applied surface where different surface material meet. e.g. masnory & concrete.
Application Procedure
Surface Preparation
Should be free of dust, grease etc. else it will affect binding. If the surface is dry. It should be moistened
with clean water.
Mixing Container
Water: Powder (8 ltr to 9 ltr water per 50kg bag) Dudhi Premix Plaster must be mixed in a clean container. Mix thoroughly with clean water for 3-5 minutes.
Application Methodology
The mixture should be applied within 60-120 minutes of preparation. If the concrete surface is smooth and dense. It’s recommended that the surface should be made rough with comb for better sticking of the plaster layer. For Application on RCC a polymer bonding Agent is highly recommended. Readymix Plaster should be applied with hand and care should be taken that it doesn’t have direct exposure to sunlight, wind and rain during it’s application.
Curing /Watering
Atter the plaster is set & dry, curing should be done which normal period compared to conventional Plaster
