Advance Screed / Plaster - UN1ON SCREED PL

Cement based water resistant polymer modified curing free ready mix plaster

Areas Of Application:

• RED BRICKS
• CONCRETE BRICKS
• AAC
• MIVAN
• PLASTER SURFACE
• CEILING
• PROTECTING COAT ON WATERPROOFING COATING

Key Feature:

• Non-sagging for higher thickness applications.
• Reduced shrinkage cracks.
• Less rebound losses leading to minimum wastage.
• Better adhesion to substrate.
• Ready to use, only addition of water is required at site.
• Low Water Permeability & Enhanced Durability.
• Uniform and smooth finish.

Properties:

• Appearance - Grey powder
• W/P RATIO - 7-8 Ltr for 40 kg bag
• Pot Life - 60 Min
• Compressive strength - > 6 N/mm2
• Dry adhesion to Substrate - Min 0.3 N/mm2

Surface Preparation:

• The substrate should be free of dust, loose particles, oil, grease, paint, and other such
  contamination which may affect the bonding. Cleaning can be carried out by suitable methods like wire brush, water jetting, mopping etc. If the surface is porous and absorbent substrate, it should be moistened with potable water.

Mixing:

• For best results a mechanically powered mixer should be used to achieve a good consistency. The selected water content should be accurately measured and poured into the mixer. The total content of the bag should be slowly added and continuous mixing should take place for 5 minutes. Re-mix again about 2 mins before application.

Application:

• Repair all cracks, holes and masonry joint by UN1ON KRACK SEAL with the help of a putty knife.
• Apply the mixed plaster uniformly on the substrate using a steel trowel.
• The plaster can then be levelled to a desired finish using masonry tools like straight edge and
  masonry bob. Different finish can be achieved using steel trowel, wooden float or sponge as per
  finish required.
• If 2nd coat is required, ensure the first coat shall be roughened to provide good grip for 2nd coat. Saturate the 1st coat prior to the application.
• To avoid undulations on plastered surface, apply mortar patch before the wall is plastered on
  perimeter of wall for levelling.

Packing:

• UN1ON SCREED PL is supplied in 40 kg bag.

Coverage:

• The approximate coverage per kg at even consistency is as follows:
• 5 mm on smooth surface is 1-1.5 sq. ft. & it differs depending on finish of the wall.

Cleaning:

UN1ON SCREED PL should be removed from tools, equipment, and mixers with clean water
immediately after use. Cured material can only be removed mechanically.

Limitations:

The product should not be used when the temperature is below 5°C and falling. The product should
not be exposed to running water on the application area during application. Exposure to heavy rainfall
prior to final set may result in surface scour. When the air or contact surface temperatures are 5°C or
below on a falling thermometer, warm water (30°C to 40°C) is recommended to accelerate strength
development. Normal precautions for winter working with cementitious materials should then be
adopted, specifically protecting the mortar from freezing in the first 48 hours after placing.
Do not add any additional substance, like cement, sand etc. or extra water to alter pot life of the mix.
These may adversely, affect the performance of the product.

Storage Conditions:

• UN1ON SCREED PL has a shelf life of 6 months when stored in covered dry shed and in sealed
  bags.
• If stored in high temperature and high humidity locations, the shelf life may be reduced.

Health & Safety Precautions:

• Cementitious mortars & slurries modified with UN1ON SCREED PL when mixed or when become
  damp, may release alkali which can be harmful to skin & eye.
• Wear suitable protective clothing, gloves, eye protection and respiratory protective equipment
  during application.
• In case of contact with skin, rinse with plenty of clean water and then cleanse with soap water.
• In case of contact with eyes, rinse immediately with plenty of clean water and seek medical advice.
