Hi all
just finished another project and need some advice?
my husband and I lifted all the old pavers as they were sinking. We bought 4 tons of sand and filled in and relaid all the pavers on the other side of original site. Now finished laying the pavers again ( used original ones as they were all whole and too expensive to buy new ones) anyway now about to use polymer sand to finish off and wondering if we need to seal the relaid pavers? The original ones were never sealed but got quite dirty over time (10 years) but not sure if that was just a weather issue or is sealing a must? Any advice very welcome!
