Hi there. I have nearly finished installing 100m2 of rainbow sandstone paving for a customer. https://nustone.co.uk/product/rainbow-indian-sandstone-paving-patio-kit/?attribute_pa_format=15.25m%C2%B2&gad_source=1&gclid=CjwKCAjw_Na1BhAlEiwAM-dm7KvAuGO-Lw0xRYMBdY-2QSm89TffRQsoa2O7hVpWUuLFat-ryYngBhoCtqkQAvD_BwE I have slurried the backs, and I was planning on using joint-it compound. They would like the patio sealed which is also a colour enhancer. I am unsure whether to do it pre pointing, or several days afterwards. Could you help at all?
