Screed consists of a ratio of sand, cement and water. When mixed properly screed provides a level base for tile, vinyl or laminate floor installations. The combination of materials in screed does not allow easy mixing by hand. Mixing the three ingredients with power ensures a proper screed capable of supporting your installed flooring without failures such as cracks, unevenness or seam separation.
Pour four bags of fine sand and one bag of cement into a cement mixer.
Turn on the cement mixer.
Add 1/2 gallon of water to the spinning mixer. Allow the mixer to run for 3 to 5 minutes. Turn off the cement mixer.
Reach into the mixer and grab a handful of mixed screed. Press your hands together to form a ball. Pull your hands apart. If the mixture does not maintain its form when you release your hands, turn on the mixer and add an additional 1/2 gallon of water to the mixture.
Continually add water and check the screed. Dump the mixture from the mixer when the screed maintains a ball shape when you release your hand.
