How to Seal Pavers with Sand Seal With Ease

Oct 06, 2020  The first layer of sand is used as a “bedding” to act as a cushion for the pavers before they are laid. Then, the second layer of sand is used for the paver joints to seal the stones together so that you have a smooth paver surface and there is no chance of weeds growing through the gaps between pavers.. Both functions, however, are carried out by two different types of sand.
