BuildWell Ready-Mix Plaster

BuildWell Ready-Mix Plaster

Instant Plastering BuildWell Ready-Mix Plaster is manufactured in modern dry mix plant with computerised batch process. Plaster is ready to use by just mixing water at site. This process eliminates job-site mixing practices. Hence it gives consistent quality with required sand mesh sizes in exact proportion which is most important for compactness of plaster. Further to have desired workability, less rebounding losses, required slump properties and overall durability, polymers are added in BuildWell Ready-Mix Plaster. What is plastering? Plastering is the process of covering rough surface of wall, column, ceiling and other parts of the building with thin coat of mortars to form a smooth, hard and durable surface capable of protecting external surface against penetration of rain water and other atmospheric vagaries. A good plaster needs to have strong adhesion on wall and ceiling with excellent water resistant, crack free and work ability properties that will protect the interior, provide flat base for painting, minimise the inconvenience of maintenance and speed up the construction. Therefore, in many ways, Plastering is as critical as structural members, brickwork, flooring, etc.,

1- All tests are carried out at manufacturer's end, specifications are derived internally except EN standard methods.

2 - Flexural Strength, Pull off Adhesion & Water Retentively is conducted as per EN standard methods. Specification for Flexural Strength is derived internally since limit are not specified in EN standard.

Application Procedure

The substrate needs to be cleaned and made free from grease and loose particles. The porous and absorbent substrates need to be pre-wetted prior to application of BuildWell Ready-Mix Plaster to prevent premature loss of water from the plaster. This will ensure that thin layer can be applied without cracking problems and proper cement hydration and adherence of the mortar to the substrate is attained. Use 7-8 liters of water for 40 kg BuildWell Ready-Mix Plaster. Pour the BuildWell Ready-Mix Plaster while mixing for 4 -5 minutes with hand or still better with a mechanical mixer to achieve a good consistency. Do not over mix. Allow mixture to stand for 2-3 minutes for additives to dissolve. Re-mix again for about 2 minutes, plaster is ready for use. Apply plaster to the substrate, using some pressure while finishing with a steel trowel or wooden float to ensure optimum bonding of the plaster to the substrate surface. BuildWell Ready-Mix Plaster can be used for interior as well as exterior wall.

BuildWell Ready-Mix Plaster is available in 40 kg bag and has a shelf life of 6 months subject to stored in a cool and dry location properly. As temperature, humidity, water addition and other parameters vary from site to site, the above information should be treated as a general guideline and Keep it out of reach of children.

Depending upon substrate and climate add approx. 7 to 8 liters of water per 40 kg bag.

BuildWell Ready-Mix Plaster approx. coverage per 40 kg bag is as under: 10-12 mm plaster on light weight blocks is 17-18 sq. ft. 10-12 mm on brick wall 14-15 sq. ft. 18 mm on light weight blocks is 11 sq. ft. 25 mm on brick wall 7-7.5 sq. ft. 10 mm on RCC 20-22 sq. ft. Coverages depends on quality and nature of substrates hence is indication. Plaster >10-12 mm must be in 2 coats.

Technical Details

PENETRATION OF RAIN WATER Large particle sizes (>3 mm) sand leads to porous surface and gives easy access to rainwater. Different grade of sand used in exact proportion ensuring compactness in plaster.
ADHESION High silt and chloride content in sand impedes adhesion properties in mortar, causing high de-bonding losses. Negligible silt and organic matter free plaster ensure strong adhesion and durability.
SMOOTHNESS Not so smooth Smooth and hard surface provides aesthetic base of plaster to work upon.
CRACK FORMATION Due to practical on site mixing practice, chances of crack formation is more. (RMP) produced at automated dry mix plant. Chances of is very negligible subjected to proper curing and application.
WATER: CEMENT RATIO Due to presence of moisture in sand it is not possible to determine exact quantity of water to be mixed. Due to dry sand used, water cement ratio is easily maintained and full strength of plaster is obtained.
GRADING OF SAND No grading (RMP) has graded sand which results compactness of plaster.
CEMENT: SAND RATIO Mistake may occur at job site mix Sand cement ratio is maintained as (RMP) is made in automated plant.
PLASTER THICKNESS Reducing of plaster is not possible. Can be reduced up to 25% keeping the required strength.
POLYMER MODIFICATION Polymer modification difficult as it involves multiple polymers and doses Polymers already added, results in overall durability
