The pot life begins when Parts A+B are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into smaller quantities. Another method is to chill Parts A+B before mixing (not below +5 °C).

Application steps

SUBSTRATE PREPARATION

Substrates must be structurally sound to provide a minimum tensile adhesion strength.

MIXING

PRE-BATCHED UNIT

  1. Mix part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
  2. IMPORTANT Mix full units only.Add both parts into a clean and dry container.
  3. Mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved
  4. IMPORTANT Avoid entraining air into the mix by over-mixing. To ensure thorough mixing, pour materials into a clean container and mix again for 1 minute.

Mixing time for A+B = 4 minutes.

BULK CONTAINER

  1. IMPORTANT Mix only the quantity which can be used within its pot life. Mix part A (resin) briefly using a mixing spindle attached to a slow speed electric mixer (max. 300 rpm).
  2. Add both parts in the correct proportion into a suitable clean, dry container.
  3. Mix parts A+B continuously for at least 3 minutes until a uniformly coloured smooth consistency mix has been achieved.
  4. IMPORTANT Avoid entraining air into the mix by over-mixing. To ensure thorough mixing, pour materials into a clean container and mix again for 1 minute.

Mixing time for A+B = 4 minutes.

APPLICATION

Reference must be made to the following Sika® Method Statement

IMPORTANT

Application by trained personnel

The application of this Product must only be carried out by an applicator that is trained or approved by Sika. The applicator must also be experienced in this type of application.

IMPORTANT

Strictly follow installation procedures

Strictly follow installation procedures as defined in Method Statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

 

Preconditions

For application in cold or hot conditions, pre-condition the material for 24 hours in temperature-controlled storage facilities.

Dry before application of the next layer or coating.

  1. At low temperatures or high relative humidity, a tacky residue (blush) may form on the surface of the cured product. To apply an additional layer of fabric or a coating remove the residue with warm soapy water to ensure adequate bond.
  2. Protect from rain for at least 24 hours after application.

For further information on number of layers or creep, consult a structural engineer for calculations.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened material can only be removed mechanically.
