Cementitious substrates

• Cementitious or mineral based substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and to achieve an open textured surface.
• Loose friable material and weak concrete must be completely removed and surface defects such as blowholes and voids must be fully exposed.
• Repairs to the substrate, filling of joints, blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, SikaDur® and SikaGard® range of materials.
• High spots must be removed by e.g. grinding.
• Outgassing is a naturally occurring phenomenon of concrete that can produce pinholes in subsequently applied coatings. The concrete must be carefully assessed for moisture content, air entrapment, and surface finish prior to any coating work. Any requirement for priming must also be considered. Installing the membrane either when the concrete temperature is falling or stable can reduce outgassing. It is generally beneficial, therefore, to apply the embedment coat in the late afternoon or evening.

Note: For the Waiting Time / Overcoating you shall refer to the PDS of the appropriate cleaner. Other substrates have to be tested for their compatibility. If in doubt, apply a test area first.

Before applying Sikalastic®-560 on primer Sikalastic®-560 diluted with 10% water:

Before applying Sikalastic®-560 on Sikalastic®-560 (without fleece) allow 1st coat to dry

Before applying Sikalastic®-560 topcoat on Sikalastic®-560 reinforced with fleece allow material to dry:

Note: Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.

* Sikalastic® Metal Primer prevents migration of bituminous volatiles and improves long-term reflectivity.
 

Note: These figures are theoretical and do not include for any additional material required due to surface porosity, surface profile, variations in level and wastage.
For the Waiting Time / Overcoating, please refer to the PDS of the appropriate cleaner and primer. Other substrates must be tested for their compatibility. If in doubt, apply a test area first.

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.

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 2^nd 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 minimal 5 cm.
3. Apply second coat of appr. 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.

Tools:

Jet washer: If dust, vegetation, moss / algae or other contaminants are present on the existing roof, a power washer is required to clean the substrate prior to the application of SikaRoof® Systems. Existing chippings should be removed by hand or scabbling prior to power washing.

Squeegee:

Useful when removing excess water from the roof after overnight rain

Drill and paddle:

Sikalastic® -560 should be mixed for one minute using a drill and paddle.

Solvent resistant short-piled lamb skin roller: Used in the application of Sikalastic®-560 to ensure a consistent thickness of the seamless SikaRoof® systems.

Thick hair brush:

For application of Sikalastic®-560 to all details and penetrations.

Stanley knife:

This tool is required when cutting Sikalastic® Vap, Sikalastic® Insulation and Sikalastic® Carrier. When the Sikalastic® Insulation is resting on an uneven substrate, the back of the board should be cut to enable maximum contact with Sikalastic® Coldstick.

Saw:

 Used when cutting thick Sikalastic® Insulation boards.

Airless spray equipment: Used only for the roof coating systems. Two spray applied layers is the minimum requirement. The pump should have the following parameter:

- min. pressure: 220 bar

- min. output: 5.1 l/min

- min.  nozzle: 0.83mm (0.033 inch)

For example: Wagner Heavycoat HC 940 E SSP Spraypack

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