Bricklaying & Repointing
Mortar colour nit changed after 4 months
Anonymous user 1 March 2024 - 3.03 PM
For clarification our developer replaced some bricks in April and July of this year. The majority of our house bricks have a reddish brown mortar, however the new bricks have dried grey. The site manager tells me they need time to cure. Is 4 months normal that they remain grey and sticking out like a sore thumb.
Are you a tradesperson and able to answer this question?
If they haven’t matched colour by now they probably won’t. It is difficult to get a complete match to an existing but it can be done by doing test samples or using dye.
It’s very possible that the mix they used is different colour sand(it happens allot of time or they may have not use the correct ratio for the pointing
It all down to the colour of sand used and what ratio the sand cement was mixed at to create the mortar

Sounds to me like the site was using ready mix mortar, which can go the reddish colour, they’ve potentially just mixed up a typical 4 and 1 and put it in. Or they have potentially used silo mix from another of their sites and just used that instead. Are you on a big housing site?
