Sand coloured mortar mix

Cut some of your existing mortar out and stick it in brick acid. You will then be left with a sample of your sand.

I am afraid that's beyond my capabilities.

It's really easy. You probably need to cut some out for your pointing, and what's left of the 5 litres you can use to clean the rest of the brickwork.

I have mixed Yellow building sand and the Mastercrete cement in 4:1 ratio and slapped it on today but end result is still grey!
After all that...

I am going to give up and buy a cement dye and just paint the mortar.

MKM have yellow building sand.

So, moving on, I have some new questions :

- How do I remove slight mortar stains on bricks? I do not want to use an acid as it all sounds quite dangerous.
- How do I remove excess dried mortar on patio slabs ?
- What dye do I use to paint mortar ? I have a tub of B&Q masonry paint.

- Try a 6:1 mix, should be yellower
- If you don’t want to use brick acid, you can only really try and go at it with a wire brush/abrasive and some water. Not sure how much success you’ll have tho
- As above if you don’t want to use brick acid, and you won’t want to use acid if they’re sandstone or similar as it can dye them
- you mix dye in the mortar mix not paint it on

This is what I have did so far :

Bad attempt on one side of the wall :

Better attempt on another side of the same wall :

and this is the excess that fell on the slabs and really needs to be cleaned up :

Will take some mortar to repoint Those joints

I did a bit of experimenting and it seems a dish washing steel wire scrub with water is the answer to getting the light mortar stains off the bricks.
