What is Stone Crete Plaster?
Stone Crete Plaster is composed of a mix of elements: cement, coarse aggregate
(usually crushed stone), fine marble powder and water. You can change the look
of the finished plaster by making changes in the elements using white cement
instead of gray cement, for example, or using crushed colored glass in place
of crushed stone. These choices can change the look of exposed aggregate
Special decorative aggregates frequently used for exposed Stone Crete Plaster and
include a variety of decorative stones in many different colors. While Stone Crete
Plaster finishers usually hide the aggregate with a smooth layer of cement paste,
you can create aesthetically appealing looks by exposing the aggregate.Stone Crete
Plaster is a 10 to 12 mm thick granular effect decorative texture.
Why Stone Crete Plaster?
- If you want rough and tough finished walls Grit Wash Plaster is the right choice for
construction external walls. This is Better known as Exposed Stone Crete Plaster This
process is hardy decorative finish can easily withstand all types of bad weather conditions.
- It is a permanent and maintenance free coating. It is ideal coating for Colleges, Government
Buildings, Hospitals, Factories, Commercial Complexes and Public Building.
- Hard, crack free surface, which also resists growth of algae and fungus and penetration of
water and moisture.
- A great alternative of natural stone for exterior.
- It’s an economical, long-lasting and maintenance-free plaster.
- You can create aesthetically appealing looks by exposing the aggregate.
- Expose aggregate is a hardest texture with rich granular effect.

What is Aggregate Plaster?
Aggregate Plaster is composed of a mix of elements: cement, coarse aggregate
(usually crushed stone), fine marble powder and water. You can change the
look of the finished plaster by making changes in the elements using white
cement instead of gray cement, for example, or using crushed colored glass
in place of crushed stone. These choices can change the look of exposed
aggregate concrete dramatically.
Special decorative aggregates frequently used for exposed aggregate plaster
and include a variety of decorative stones in many different colors.
While aggregate plaster finishers usually hide the aggregate with a
smooth layer of cement paste, you can create aesthetically appealing
looks by exposing the aggregate
Grey Cement OR White Cement.
Calcite/Marble Powder - (200 Mesh).
Marble Chips (Size No.6mm to 9mm).
Synthetic Inorganic Pigments - if required.
Water Proofing Compound - 2% by wt. of Cement.
Fungicides: 2 EHA - (0.2% by wt.)
Exposed Aggregate Plaster can be done on any type of masonry work viz., stone/brick/block and RCC wall. In order to get a proper inter coat adhesion, the base coat has to be prepared.
The base consists of ordinary Portland cement and sand rough plaster in a 1:3 or a 1:4 mix.
The base plaster should have a thickness of 12 mm to 15 mm .
Take sections of wood or aluminum baton strips as per groove size and cut them according to the panel size. Fix this with nails on the walls as per the design.
Ensure proper fixing of the sections with cement.
Size of grooves may be 9 mm, 12 mm or 15 mm.
Prepare a dry homogeneous mix by taking 3 parts of Cement and 1 part of fine marble powder (200 Mesh) preferably calcite powder for permanent whiteness, by weight.
Add Marble chips 6 to 7 parts to above mix by volume. Prepare the mortar by adding water to the dry mix and apply in between the panels, from top panel downwards. Level the plaster in between the sections and allow drying for 2 to 3 hours.
After that expose the marble chips by washing the cement off from the top with the help of water and a hard nylon bristle brush. Wash the surface in such a way that chips do not come out from the plastered surface.
If the cement becomes very hard and the chips are not fully exposed, then wash with a 2% solution of Hydrochloric acid followed by another wash with clean portable water.
Finally after complete washing, remove the sections from the plaster to get grooves.
Grooves may be filled with any color for contrast.
Synthetic inorganic pigments may be added to the mix, in case of colored Grit Wash.

|2B No. or 4 to 7 mm
||10 / 12 mm
For proper bonding the plaster should be rough. Marked by combing the surface with wavy lines using a wire brush or nail comb.
The base should be hard and properly cured for a minimum of 5 to 6 days.
|Do’s and Don’ts
The walls to be finished should have proper Damp proofing Course (DPC) at plinth level, roof levels and parapet wall levels, to avoid any penetration of water. Parapet walls should have good coping blocks laid evenly
All down-take pipes must be checked at joints and particularly at junctions / braches to avoid seepage of water.
The walls must be clean and dry. After the removal of algae, leeches and any other organic growth, the spores should be killed with suitable fungicides.
Wooden floats or batons should not be used. This will help in protecting whiteness.
Plastering should not be done sun-facing during cloudy weather.
Aggregate Plaster is a decorative plaster & for aesthetic looks, Please do not perform any civil work,
other heavy operations, fabrication of steel plates / pipes etc, which will affect the appearance of
the aggregate plaster and aesthetics. Final work of the site for e.g. plumbing, grill fixing or any
other cementing work must be completed in all respect before application.
