111 Lion-Ultra Bond(SBR)

DESCRIPTION

  • 111 Lion-Ultra Bond is based on modified styrene butadiene latex supplied as a ready to use bonding agent in liquid consistency. It is used for repair of spalled concrete – floors, columns, beams, chhajas, slabs & waterproofing of toilets & bathrooms, small terraces etc. as it bonds strongly to old & new concrete and to plasters. It reduces shrinkage, prevents cracking, dust pick up & improves abrasion resistance.

Areas of Applications

  • For concrete repairs-Spalled concrete of floors, columns, beams, chajja, slabs, parapets, etc.
  • For waterproofing-Small roof terraces, sunken portions of toilets & bathrooms, chajja & lift pits, balconies.
  • As a bond coat-For bonding of new concrete to old. concrete, masonry stone work, plastering.
  • For cladding-Fixing or re-fixing of slip bricks, tiles, stones & marble bedding.
  • As external rendering-Weatherproof & frost resistant render.
  • As bonding slurry coat for pinhole treatment on concrete surface.

Features & Benefits

  • Multipurpose- It is multipurpose & economical product, easy to use.
  • Cracking-It prevents cracking by improving flexural strength.
  • Hardness-Improves the hardness & prevents dust generation.
  • Shrinkage- Reduces drying & aging shrinkage cracks
  • Bonding-Bond strongly to concrete, masonry, stonework, plasters, cementitious surfaces.
  • Erosion & corrosion-Improves erosion resistance & prevents corrosion.
  • Abrasion resistance- Improves abrasion resistance of the cement mix.
  • Grouting-Reduces viscosity of cement injection grout for better fluidity & bonding

Method of Application

  • 1. SURFACE PREPARATION
  • Clean the surface with wire brush or scrubber to remove hidden dirt, loose particles & dust. Degrease the surface by using suitable solvents
  • Repair the spalled concrete portion by saw, cutting the extreme edges of the repair location to a depth of at least 10 mm to avoid featheredging & to provide strong bond Clean the concrete surface to remove any contamination where breaking is not possible. Roughen the surface by light scrabbling or grit blasting
  • For priming of concrete substrate, the surface should be thoroughly saturated with potable water. Remove any excess of water prior to application. over any excess of water prior to application
  • 2. WATERPROOFING COATING
  • For a waterproofing coating Mix 111 Lion-Ultra Bond: Cement in the ratio 1:1.5 by volume
  • Mix for 2-3 minutes to avoid air entrapment. Keep on slowly adding cement to 111 Lion-Ultra Bond until the required consistency is achieved
  • Brush apply 2 coats of the mix in a span of 4-6 hours on the prepared concrete substrate. Overlay the coating with a protective screed to the desired slope & thickness.
  • 3. BONDING PRIMER
  • For a bonding primer coat of 111 Lion-Ultra Bond mix: Cement in the ratio 1:1.5 by volume.
  • Brush apply 1 continuous coat of the mix on the prepared concrete substrate.
  • Ensure to overlay the repair mortar when the bond coat is still tacky
  • 4. REPAIR MORTARS & RENDERS
  • A suitable mix ratio for patching repair mortar or render is as follows:
  • Mix design - Portland Cement: 50 kg, Washed sand: 150 kg, 111 Lion-Ultra Bond: 6-7.5 kg & Water: 10 Lit
  • 5. FLOOR SCREEDS & PCC
  • A suitable mix ratio for patching repair mortar or render is as follows:
  • Mix design - Portland Cement: 50 kg, Washed sand : 75kg, 6mm downsize aggregates : 75 kg, 111 Lion-Ultra Bond: 6-7.5 kg & Water: 10 Lit
  • 6. MIXING & APPLICATION
  • A forced action mixer is essential (PAN Mixer) & recommended to ensure that 111 Lion-Ultra Bond mortar is thoroughly mixed. Use a suitable sized drum with heavy-duty electrical drill machine fitted with spiral paddle mixer at slow speed of 400-500 rpm.
  • Hand mixing is permissible only for 25 kg or less quantity
  • Charge the mixer with required quantity of clean & dry sand(or coarse aggregates as needed), cement & mix for 1-2 minutes, then add the recommended dosage of 111 Lion-Ultra Bond dispensed in water which is pre-batched. Mix for 2-3 minutes to avoid air entrapment. Keep on slowly adding water until the required consistency is achieved
