Can you use white distilled vinegar to etch concrete?
Concrete is very hard. To do any good in etching it you need something very strong. Muriatic Acid is the only thing that I have found that works. How strong you mix it depends on the concrete. Some concrete that was poured with a lot of water in the mix will need less Acid. Concrete that is smooth and hard will take more. Muriatic Acid is caustic. Read the direction. Use rubber gloves; safety glasses; and a respirator. For a large project, such as a driveway or Patio. Use a plastic garbage can. Fill with 10 gallons of water. Carefully pour one gallon of Muriatic Acid into the water and mix with a wooden paddle. Take a plastic watering can and fill it with the solution. Wet your concrete with a water hose, then carefully pour the Acid solution onto the concrete. It will bubble and foam. This is the acid etching the concrete. Let it set for about 15 min. Scrub with a stiff push broom, and then rinse with a water hose. The acid will kill plants and grass. Steve Schillinger sds@knology.net = Safety Note = Make sure you put the water in the garbage can first--adding water to acid is a sure way to get splashed with concentrated acid.

What is the ratiop of cement water and sand?
There are multiple mixes of concretes for different uses. A common standard mix is 3:2:1 mix 3 parts aggregate, 2 parts sand, 1 part portland cement, mixed with about 1 part water (don't make the slurry too wet), just enough to wet the material and cause it to adhere in a mass plus a little bit. A mix I like is a 3:1-1/2:1 mix. It's a little bit tougher mix. for mortar again a 3:2:1 mix of sand, cement, lime with just enough water to make it workable. For grouts I'll use a little less sand or a fine beach sand, if it's not sticky enough I'll increase the cement.

Yes you can. However, you MUST use a proprietory waterproofer in the mix. This is best used when concrete is purchased from an industrial supplier (ready mix) as the mix is created and maintained in a slurry format until delivery. The walls are shuttered and filled. Drying takes place and then the floor is poured in as a second fix option.
