Some sealants may impart a glossy, wet look that isnt always to everyones 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 porisity 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.
