Sika Sikalastic 560

Uses

• For roof waterproofing solutions in both new construction and refurbishment projects
• For roofs with many details and complex geometry
• when accessibility is limited
• For cost efficient life cycle extension of failing roofs
• For a reflective coating to enhance energy efficiency by reducing cooling costs

Features & Benefits

• One-component - ready to use
• Cold applied - requires no heat or flame
• Seamless waterproofing membrane
• UV-resistant and UV stable
• Highly elastic and crack-bridging
• Easily recoated when needed - no stripping required
• Economic – provides a cost-efficient life cycle extension for failing roofs
• Low VOC emitting water-based coating
• Excellent adhesion on porous and non-porous substrates
• Water vapour permeable - allows the substrate to breathe

Applications Instructions

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, and 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 to 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 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 the 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 a 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. 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).
• 5. Please note, always begin with details prior to starting with waterproofing the horizontal surface.
