BestLatex R126

New to old concrete bonding and water-proofing agent

Advantages:
  • Increase the waterproofing capacity for slurry coat and a cement-sand system.
  • Increasing significantly the bonding and adhesion strength of each material and new to old concrete.
  • Minimize shrinkage and cracks. Increase elasticity for the cement-sand system.

  • Increase chemical corrosion resistance and abrasion resistance for flooring screeding mortar.
  • As a repair layer which are solve small cracks and small defects on the surface.
  • Stable under an alkane environment. Stable under exposure to UV rays.
  • Non-toxic, non-pollution. It could be applied for waterproofing in a project which is directly in contact with water.

BestLatex R126 is a modified Styrene Butadiene emulsion copolymer used to mix with cement or sand–cement to increase adhesion, waterproofing, and anticorrosion for building surfaces.

  • Slurry layer (used to waterproof or connect new to old concrete). 
  • Thin layer of patchwork mortar to finish the surface. 
  • Surface waterproofing mortar. 
  • Abrasion-resistant floor screeds; Concrete repair mortar. 
  • Abrasion-resistant linings; Tile adhesive mortars. 
  • Waterproofing masonry mortars.

Appearance / Color:

  White milky liquid

Chemical Origin:

Modified Styrene-Butadiene Copolymer.

Density:

   1.01 ± 0.02 (25 o C )

Packaging :

1; 5; 25L/ can; 210 L/drum

pH:

7.0 ÷ 9.0 (25 o C ) ​

Storage Condition :

Store in a dry, cool place, freeze-free area

Shelf - Life :

12 months in original



Surface preparation: 

  • The surface must be clean, and remove dust, laitance, grease, and any other contaminants.
  • If the surface is not rough enough, roughen the surface by using suitable mechanical methods before application. Saturate an entire surface with clean water but no water remains.

Material preparation:

  • Aggregation (sand) must be selected carefully and clean, and the particle size of sand must be suitable for the width of grout and the requirement of surface fineness when applied. 

For Waterproofing and old to new concrete bonding slurry: 

Mixing ratio: 

  • 1L BestLatex R126 + 1.5L Water + 5kg Cement = 4.1L Slurry

Application: 

  • Pour the cement into the mixture BestLatex R126 and water (prequantified), and use a paddle to mix until homogeneous. Apply the connected layer of 1 - 2mm thickness on the water-saturated surface first and pour new concrete or plaster the waterproofing mortar as soon as the cement slurry-BestLatex R126 is wet. 

Consumption:

  • 1 liter of BestLatex R126/ approx. 5m2 applicable. 

For waterproofing mortar: 

  • Mixing ratio: 1L BestLatex R126 + 4.5L water + 9 kg Cement + 27 kg sand= 41.5 kg mortar. 

Application: 

  • Apply the waterproofing mortar layer as soon as the waterproofing slurry layer is still wet.

Consumption: 

  • 1 liter of BestLatex R126 / 2m2 / 1cm of thickness. 

Caution: 

  • BestLatex R126 must always be used with cement, and should not be used alone as an independent adhesive agent. Sand must be clean, free of dust, and have a suitable size of particles. Do not use cement which is time over and slumping.

 Lớp kết nối bê tông cũ-mới, xử lý mạch ngừng, joint lạnh:

Pha chế

  • 1 Lít BestLatex R126 + 1 Lít nước sạch + 4 Kg xi măng = 3,3 Lít hỗn hợp.
    Cho BestLatex R126 vào lượng nước đã định lượng trước, dùng cánh khuấy tốc
    độ chậm trộn đều trước khi cho từ từ lượng xi măng tương vào và trộn cho đến khi hỗn hợp đồng nhất.
