Stucco  Rolla

A ready mixed dry (colored) cement paint

Composition: Stucco Rolla is a ready mixed dry powder composed of

·   a number of mineral binding materials the most important of which is Portland Cement 

·   well graded aggregate composed of inorganic mineral compounds  

·   polymeric and mineral admixtures necessary to achieve the desired physical, mechanical and chemical properties 

·   Coloring oxides.

Scope of utilization: Stucco Rolla is a cement paint, white or colored , to be applied directly on top of cement mortar under-coat in external finishing works & internal decoration. It can also be directly applied on concrete surface as well as on clay, cement and sand-lime brick walls due to possessing of high adhesive properties

Technical  characteristics:

·   The product is in the form of a dry powder with a bulk density of 1.25 tons/ m3

·    Ready for direct use after the addition of water only

·   The initial setting period of the paste or thick slurry ranges between 55 to 60 minutes which provides a reasonable period for application

·   The slurry has high adhesive properties to existing undercoat even fair face

·   The texture of the final surface range from striated (tree trunk texture) to granulated (coarse to fine) according to the water content of the slurry. The thicker the slurry the more the tendency to striation and the thinner the slurry the more the tendency to fine granulation. Excessive water would destroy the coherence of the slurry and prevent the ability to form a layer with the required thickness of at least 1.5 mms .

·   The finished coat has high resistance to humidity and water and possesses good breathability. It has good resistance to prevailing environmental conditions

Method of utilization:

·   Add about 8.5 to 9 liters of water to each sack of 25 kgs to form a thick slurry of suitable workability. This amount of water could be increased to about 10 liters if a final fine texture is desired. The slurry may be left to mature for a short period of time i.e. between 5 to 10 minutes before application.

·   Dust should be removed from the surface by using a brush and wetting or washing by water.

·   Apply the slurry to the wall and spread it using painting rolls to obtain the desired thickness and texture.

·   The final surface could be sprinkled with water after 24 hours of application to achieve proper  maturing.

 Advantages:

·   Easy application

·   Requires only the addition of water

·   Gives final surface in one stage only

·   Economic

Period of application:

 within 45 minutes after the addition of water to the dry powder.

Rate of use:

 between 3.5 to 4 kgs / m2. This rate may slightly increase according to evenness of the wall surface and the desired thickness.

Storage:

 12 months from the date of production in shaded and dry atmosphere.

Package:

Sacks 25 kgs
