INSTALLATION

Surface condition:

  • The cracked surface must be clean, dry, not bonding impurities easy blister, remove all dust by proper mechanical methods. 

Surface preparation

  • The cracks must be cut or sawed out to a minimum width of 5mm, a depth greater than or equal to 1.5 times the width. The crack bottom has U-shaped. Using a compressor air to clean the cracked surface. 

Mixing:

  •  Two components A and B should be carefully mixed under the right ratio by slowly stirring (at speed of 300  ÷  400 rpm).
    The minimum mixing duration should not be less than 03 minutes and can be longer until reaching the required homogeneity.

Application:

  • Use a steel trowel or suitable tools to fill holes on the surface. For vertical surface or the underside of the ceiling should apply with a thickness of each layer not over 5mm to avoid sagging of material.
  • Note: Do not use a material that has rime application over.

 Cleaning:

  • Use BestThinner SC-01 to clean instruments as soon as after the execution and before the mixture’s hardening

Safety:

  • Both components are non-toxic and non-flammable.
    This product can be allergic to the skin, therefore should be prevented from direct contact with the skin. It is advised to wear PPEs while handling the product.
  • In case of accidental eye contact, wash with fresh water and seek medical advice immediately.
