I finished the grouting at home today. Grouting can be so time sensitive. If you clean it too early you remove grout and too late and it becomes hard to clean. Today I was lucky and got it just right. I mixed grey Portland cement today since I’ve been working with it on my own projects. The proportion I use is one part Portland to 3 parts yellow sand. You can use commercial grout unless you have big spaces between tiles. When the tiles dry and lighten I rub off grout with a dry sanding sponge. Then I use a wet sponge that has been rung out and not too wet. The last step is to use a dry towel to polish the tiles a bit and then you are done. The grout can be stained with diluted acrylics if needed or you can add powder or liquid color to the mix. I will color the base once it drys. The doves still need to be filled out with a white Portland cement and white sand mix. It is harder to find but the very fine bright white sand sometimes used in ashtrays is my favorite. Next I will put a foundation in the garden and install in the Bancroft garden. I can’t wait!
