At this point, cover any surrounding landscaping with tarp that may be damaged by water or chemicals in the cleaning products. Be sure to also cover metal objects.
If the growth is too heavy to remove by hand, spray a vegetation killer and wait at least two weeks before cleaning the pavers.
You may use a wire brush or scouring pad instead. Don’t overdo it, as these tools can scratch the paver surface.
However, power washers can sometimes cause more harm than good (by excavating sand in between paver joints), so be careful if you decide to use a power washer. [8] X Research source
Polymeric sand locks the pavers together more effectively than regular sand.
Besides getting the advice of a specialist, always follow the directions on the sealer project you plan to use. Wear safety gloves to protect yourself from harsh chemicals in the sealant. [13] X Research source
The sealant instructions should indicate the drying time for the first coat of sealant, before the second coat can be applied.
Try not to let the sealer puddle in any areas. If you see this happening, simply continue to spread out the sealer with your roller brush.
