How to Mix Portland Cement With Sand Hunker

Step 3. Use Portland Cement to create beautiful sculptures. The best ratio is 1 part silica sand to 2 parts cement, 1 part latex, a small amount of microfibers and 4 parts water. This will give you a mixture that is the consistency of clay. Tip. Only mix as much as you can use in two hours. Do not add water to the mixture if it starts to get hard.
