For smaller projects, 30 lbs. or less, mixing the concrete by hand is pretty easy. It can be mixed in a 5 gallon bucket, a wash tub, or on a plastic sheet or a tarp. When you're getting your hands in the mix like this, be sure to wear thick gloves. Concrete is caustic and thinner gloves will rip too easily. It helps to have a hand trowel or a small shovel to scrape the sides and bottom of the bucket.Supplies:
Paddle Mixer Attachment (optional):
- THICK Rubber Gloves
- Particle Mask
- 5 - 8 Gallon Bucket / Wash Tub / Similar
- Bucket / Clean Water
Using a 1/2" corded or cordless drill with a paddle mixer attachment is one way to mix the dry material. After the water is added, the concrete will be more difficult to mix, unless you have a very powerful drill.1.
Weigh out all of the DRY
material and add it to a bucket (Sacked Concrete Mix, Dry Pigment, Dry Water Reducer, Fiber, or any all-in-one Admixture like CHENG Pro-Formula).2.Blend
the dry material together until it's a uniform color. Always wear a dust mask when mixing dry concrete.3.
Break apart any clumps of concrete or toss them out if they won't break apart.4.Measure out 3/4 of the recommended water
and mix. If you're using liquid pigment or liquid water reducer, pre-blend it in this water.5.Add the water to the dry material and mix
. Scrape the sides and bottom of the bucket as you go, making sure you don't leave any dry material.6.Add the remaining water gradually as needed
until the mix is a workable consistency. If the mix is too stiff, you may need to add a little bit of water. There should be no dry pockets at this point. Mix thoroughly before casting.
Clean out the mixing bucket with water. Don't pour it down the drain because it contains active cement and it will clog the drain.
