Yes. You should always fill expansion joints. Expansion joints account for cement’s natural properties of expansion in the heat and contraction in the cold. Be sure to choose a flexible sealant. Once the polymeric sand has set up, heavy rain won’t hurt it. But if you have just finished applying polymeric sand and it hasn’t yet set up – like in the first 24 to 48 hours – then you’ll need to protect your patio from a downpour. Use a tarp or plastic sheet. This is very much the same process as pointing a patio, but you will need to do a little prep beforehand. First you will need to remove the old pointing with a hammer and a bolster or plugging chisel. Once the rim hardens, no more water can penetrate. The sand underneath the rim will be just loose sand and no amount of watering will penetrate then. Everbuild Geo-Fix is another quality offering. You simply lay in sand to about 1 inch off the surface depth. Then brush in the grout level to the surface. This is another brush in patio grout that’ll make a huge difference in reducing your maintenance going forward. I chose this over the standard Geo-Fix patio grout because it can be worked in the rain which is kind of a big deal in the UK.
