Hi, I've just laid some white paving and am looking to fill the joints (~7/8" wide) with whitish mortar. However I'm having difficultly locating white sand anywhere. b&q list it but in reality no stores stock it. I tried a mix of white cement (snowcrete) and sand 1:1, but my builders sand is almost red and so the result is yellow.
Is there any alternative way to get white mortar that I'm missing? I've heard of cement dyes, but is it possible to turn a mix of red builders sand to white with a dye?
