Application steps

SUBSTRATE QUALITY

The cementitious substrate should be sound and of sufficient strength (min. 25 N/mm²). Minimum pull-off strength 1.5 N/mm², it should be free from grease, oil and contamination.

SUBSTRATE PREPARATION

All dust loose and friable materials and glaze or varnish of tiles must be completely removed by mechanical means. Existing coatings must be inspected, cleaned and mechanically ground to achieve a sound, gripping substrate. In case of bad adhesion to the substrate, existing coatings must be removed.The uneven surface should be properly treated by suitable Sika material to get a plain surface.Prime the prepared substrate with Sikalastic®-510 PK Primer by brush or roller.

 

APPLICATION

Sikalastic®-510 PK is supplied in a single component pack and is in ready to use form. Stir thoroughly before application.
Within 45 minutes of priming apply 1st coat of Sikalastic®-510 PK by brush or roller. Do not spoil the dry surface while walking on it for application.
Place Sika® Fab1 over the first coat when it is in tacky condition.
Apply the 2nd and 3rd coat of Sikalastic®-510 PK following the same above procedure at suitable time interval of 24 hours between the two coats.

CLEANING OF TOOLS

Clean all tolls and application equipment with clean water immediately after use. Hardened / cure material can only be removed mechanically.
