Block Paving Sealants
- Application
- For new surfaces Sealants should never be applied to freshly laid paving. It usually takes at least 3 or 4 months for the jointing sand to properly settle and for any efflorescence to disappear. We recommend that you do not seek to get your paving sealed for at least 6 months after installation. Should it be sealed too soon, you will be sealing in any problems and the application of sealant cannot easily be reversed.
- For old surfaces fully clean off with power wash, apply premium weed and moss inhibitor. Allow to dry thoroughly (a minimum of 3-4 days of completely dry weather) and re-apply jointing sand prior to sealant application.
- Ensure the entire area is completely dry, clean and free of debris.
- Remove all traces of weeds, algae stains, lichen and any other old stain.
- Ensure no sand remains on the surface of the blocks.
- On occasion, washing or pressure cleaning will cause reactive efflorescence and substrate saturation. Therefore allow at least 2 weeks between cleaning and application of sealant to allow to dry out and to check for reappearance.
Test Patch
Some sealants may impart a glossy, wet look that isn't always to everyone's taste and some products may not be suitable for your particular type of paving. Therefore, it is always advised to test the sealant on a small discreet area before applying it to the whole driveway or patio.

Always perform a test patch on block paving as you may find that the ground is holding water. The block may appear surface dry, however the block underneath may still be wet.

Depending on the porosity of the blocks, a primer coat may need to be applied, this would allow the smaller pores in the blocks to be filled prior to application of neat sealant. Dilute the sealant with xylene at a ratio of 1:1. Its advised that sealants are applied to block paving by someone in the trade. This is because once the sealant has been applied, it cannot easily be removed. A professional will also be able to advise on how many coats should be applied.

Please note solvent based sealants may bloom should damp or moisture be present before full cure has taken place. Solvents are released during the cure that normally permeate through the sealer, however if the sealant is applied too thickly, the substrate is damp or cold, blooming may occur giving the appearance of milky white or silvery cloud effect, this may look patchy, spotty in certain areas or across the whole driveway or patio.
