Application Instructions
SUBSTRATE QUALITY / PRE-TREATMENT
- For new block paving areas, remove all loose materials by brush or vacuum.
- Ensure the joints are filled with compacted Sika Setting Sand or kiln dried sand before treating with Sika Block Paving Seal.
- For existing block paved areas remove all traces of weeds, algae and lichens with Sika Mould Buster.
- Remove oil, grease and diesel stains.
- Ensure all areas are completely dry before applying Sika Block Paving Seal.
- To ensure the paving is completely dry, scrape out some jointing sand to a depth of up to 10mm. If the sand is dry then the blocks may be treated.
APPLICATION
- Mix thoroughly before use.
- Treat the perimeter of the block paving area first.
- Apply the first coat by roller, spreading liberally and uniformly, making sure the Sika Block Paving Seal does not puddle.
- During application always ensure a wet edge is maintained to avoid a striping effect.
- Repeat the process leaving a maximum of 24 hours between coats.
- Apply the second coat at right angles to the first.
- Do not over-apply.
- Allow at least 6 hours before pedestrian traffic and 24 hours for vehicle.
- Protect from moisture during curing.
- It is always recommended that a trial area be treated to ascertain an accurate measure of consumption and to ensure the finished appearance is acceptable.
