Application steps

SUBSTRATE PREPARATION

The surface must be sound, of sufficient strength, clean, dry and free of dirt, oil, grease and other contamination. Depending on the material the substrate must be primed or mechanically cleaned. Grinding may be necessary to level the surface.
Suitable substrates are such as: concrete, bituminous felts and coatings, metal, brickwork, asbestos cement, ceramic tiles, wooden substrates.
For detailed information regarding substrate preparation and primer chart please refer to Method Statement No. 850 94 03.
 

MIXING

Prior to application, stir Sikalastic®-560 thoroughly for 1 minute in order to achieve a homogeneous mixture.
Over mixing must be avoided to minimise air entrainment.

APPLICATION

Prior the application of Sikalastic®-560 the priming coat if used must have cured tack-free. For the Waiting Time / Overcoating please refer to the PDS of the appropriate primer. Damageable areas (door frame) have to be protected with an adhesive tape

Roof Coating: Sikalastic®-560 is applied in two or three coats. Prior to the application of a 2nd coat the indicated waiting time in the table above shall be allowed.

Roof Waterproofing: Sikalastic®-560 is applied in combination with Sikalastic® Fleece 120 or Sika® Reemat Premium.

  1. Apply first coat of appr. 0.75 kg/m2 (for non-absorbing substrates) – 1.00 kg/m2 (for absorbing substrates) of Sikalastic®-560 on a length of approx. 1m.
  2. Roll in the Sikalastic® Fleece-120 or Sika® Reemat Premium and ensure that there are no bubbles or creases. Overlapping of the fleece minimum 5 cm.
  3. Apply second coat of approx. 0.25 kg/m2 - 0.5kg/m2 coat right into the wet fleece to achieve the required film thickness. The entire application shall happen while Sikalastic®-560 is still liquid, wet in wet.
  4. Repeat step 1–3 until the roof area is waterproofed.
  5. After the two coats are dry, seal the roof area with one or more additional coats of Sikalastic®-560 (≥ 0.5 kg/m² per coat).

Please note, always begin with details prior starting with waterproofing the horizontal surface.
For detailed information regarding application method please refer to Method Statement No. 850 94 03.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
