Application Details

Substrate Treatment


Cementitious substrates:

New concrete should be cured for at least 28 days and should have a Pull off strength

>/= 1.5 N/mm2.

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. 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.

Prime the substrate and always use a reinforced system.


Brick and stone:

Mortar joints must be sound and preferably flush pointed. Use localised reinforcement over joints and prime before applying Sikalastic-560.

Slates, tiles, etc.:


Ensure all slates/tiles are sound and securely fastened, replacing obviously broken or missing sections. Fully glazed tiles must be abraded prior to priming and subsequent treatment with Sikalastic-560.


Bituminous felt:

Ensure that Bituminous felt is firmly adhered or mechanically fixed to the substrate. Bituminous felt should not contain any badly degraded areas. Prime and always use a totally reinforced system.


Bituminous coatings:

Bituminous coatings should not have sticky or mobile surfaces, volatile mastic coatings, or old coal tar coatings. Prime and always use a totally reinforced system.



Metals must be in sound condition. Abrade exposed surfaces to reveal bright metal. Use localised reinforcement over joints and fixings.


Wooden substrates:

Timber and timber based panel roof decks are to be in good condition, firmly adhered, or mechanically fixed.



Ensure the existing material is sound and firmly adhered. Remove any oxidized layers and use localised reinforcement over joints.


Existing SikaRoof CET Systems:

The existing SikaRoof CET Systems should still be soundly adhered to the substrate.

Application Instructions



Prior to application, stir Sikalastic-560 thoroughly for 1 minute in order to achieve

homogeneous mixture.

Over mixing must be avoided to minimise air entrainment.


Application Method / Tools

Application Method (please refer to the most recent issue of the Method Statement)


Prior the application of Sikalastic-560 the priming coat 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 coats. Prior to the application of a 2nd coat the indicated waiting time in the table below Waiting Time / Overcoating shall be allowed.


Roof Waterproofing:

Sikalastic-560 is applied in combination with Sikalastic Fleece 120.


1. Apply first coat of approximately 1.0 kg/m2 of Sikalastic-560 on a length of  approximately 1m.

2. Roll in the Sikalastic Fleece-120 and ensure that there are no bubbles or creases. Overlapping of the fleece minimal 5 cm.

3. Apply second coat of approximately 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 waterproof.

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 details follow step 1-5.




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.



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.


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


Cleaning of Tools

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


Waiting Time / Overcoating

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

1) Assuming that all dirt has been removed and contamination is avoided.

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



Relative humidity






+10 C


~ 36 hours

After thorough cleaning 1) Sikalastic-560 can be overworked at any time


+20 C


~ 24 hours

+30 C


~ 12 hours


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


Notes on Application / Limitations


Do not apply Sikalastic-560 on substrates with rising moisture.


Always apply during falling ambient and substrate temperature. If applied during rising temperatures "pin holing" may occur from rising air.


Ensure that Sikalastic-560 is totally dry and the surface is without pinholes before applying any top coat.


Do not allow temporary ponding to remain between coats on any horizontal surfaces or until the final coating has totally cured. Brush or mop surface water away during this time.


Sikalastic-560 should not be applied on roofs subject to long-term ponding water with subsequent periods of frost. In cold climatic zones for Roofing structures with a pitch of less than 3% appropriate measures must have to be considered.


Sikalastic-560 applied on roofs subject to long-term freezing at temperature around the minimum service temperature of -10 C should always be reinforced with SikalasticFleece-120 in order to guarantee sufficient crack-bridging ability.


Do not apply Sikalastic-560 directly on insulation boards. Instead use a separation layer like Sikalastic-Carrier between insulation board and Sikalastic-560.


Sikalastic Fleece-120 can be used as total reinforcement or for partial reinforcements over dynamic cracks and joints.


Sikalastic-560 is not recommended for pedestrian traffic. In case pedestrian traffic is unavoidable, Sikalastic-560 shall be covered with appropriate elements such as tiles, stone plates or wooden panels.


Do not apply cementitious products (e.g. tile mortar) directly onto Sikalastic-560. Use an alkaline barrier, for example kiln dried quartz sand.


The fire resistance performance has been tested internally according to ENV 1187 BRoof (T1)
