Getting a Light Coloured Mortar Mix for Slab Pointing
Posted: Wed May 13, 2020 1:01 pm
Hi All,
I've recently completed laying a patio with light coloured cast-concrete slabs. These are on mortar bed made up of Cement and Sharp Sand.
Now it comes to the pointing (the gaps are between 6-8mm) I had planned to use a 4:1 Builders Sand / Cement mix, knowing that the Grit Sand / Sharp Sand is really too stony for a good pointing finish.
However, buliders sand is generally yellow and I do not want a yellow / buff finish.
Reading around, one option is an expensive pre-mix compound (want to avoid extra cost) or White Cement + Silver Sand. However on looking up a description of Silver Sand, it says it's basically Grit Sand with the Iron washed out. So this will be just like using Sharp Sand right?
