There are a few options when it comes to pointing setts the traditional way of using sand and cement mortar is still very popular and comprises mixing the sand and cement in a 4 to 1 ratio. This is then mixed to a wet but workable consistency, which is then pressed into the joints using a pointing trowel or Iron. This method is very time consuming and expensive due to the labour costs involved, which has resulted in alternative products for easier installation being developed.
A very good alternative to the traditional method is Flowpoint, which is a cement-based product used mainly by the civil engineering industry but is a far quicker method and offers superior frost resistance to mortar pointing. This product is mixed into a slurry and then poured into the joints, it then hardens within ten minutes and the excess can be brushed and hosed off. We recommend this product is used only by professional trades people as mistakes are very hard to rectify if used incorrectly.
