Hi,
I need to patch up some grout on the patio and in my hallway that is sand and cement mixed grout. I know the ratio is 3:1 sant to cement but what is the best type of sand and cement i need to use. thanks
Hi nika,
For repairing sand and cement grout in areas like a patio or hallway, you can use a standard fine building sand mixed with general-purpose cement. The typical ratio is around 3 parts sand to 1 part cement, but you can adjust slightly to achieve a workable, firm mix that can be properly packed into the joints.
Before applying, remove any loose or deteriorated grout and clean out the joints thoroughly. Lightly dampen the area without leaving standing water. Mix the sand and cement dry first, then slowly add water until you reach a stiff, workable consistency. Pack it firmly into the joints and smooth it off to match the existing finish. Keeping the repair slightly damp while it cures will help reduce cracking.
If you would prefer to skip measuring and mixing ratios yourself, we also sell premixed sand and cement products in bags that only require water to be added. These can be a convenient option and help ensure consistent results.
Please let me know if you have any questions.

Hi Mitchel,
Thanks for that. The premixed sand and cement would be a 50/50 ratio would it not be? thanks
Hi @nika,
No, our premixed sand and cement bags aren’t a 50/50 mix. The would be formulated with a higher proportion of sand than cement, similar to the standard of about 3 parts sand to 1 part cement, so they’re easy to pack into joints and less prone to cracking. You just need to add water, and the mix is already optimised for strength and workability, so there’s no need to adjust the ratio yourself. Mitchell
