Q:What do I need to do to add a concrete brick wall to a concrete brick building with cement floor?
if it is an inside wall.work off the floor.no problem.wall should be double brick or 8thick.
Q:what happens if you get rubber cement on your hands?
Rubber cement will rub off easily. You should get it off as quickly as practical. The glue does contain chemicals, and isn't the best thing to absorb.
Q:About how long is it take cement to dry?
It varies, best way to find out is by reading the bag the cement mix is in. Some are quick drying while others require longer.
Q:What is cement called with no rocks?
I guess by rocks you mean aggregate, i.e. small stones. You can mix concrete without aggregate but it's not as strong. Pretty much any time you mix concrete it will have aggregate in it and you should be using rebar or wire mesh to reinforce it.
Q:what's the difference between cement and mortor mix?
Morter is for brick and stone. Cement is for paving and reinforcement.
Q:Cement bird bath has sprung a leak?
GO TO HARDWARE STORE ASK 4/ A SEALIN, IT WILL FIX THE LEAK. IT WON'T LEAK AFTER THAT, I DON'T THINK #1 !!
Q:What is the paint on the surface of the cement board?
The cement board is prefabricated and also cast
Q:get writing out of cement?
Pouring cement into the grooves won't help. You may have to dig it up and put in new cement. Even caulk, which will fill the grooves, won't match the color, and it will still be visible. But I'd try that first. Get some cement caulk from a hardware store. At least you can tell your parents you tried. maybe put a lot of dirt over it, they may not notice if for a while. .
Q:Is blacktop or cement cheaper? I have a gravel parking space that is about 10 ft long and 30 ft wide.?
blacktop is cheaper, but needs to be resealed often. cement is less work later, but because it's permanent it may increase your property taxes
Q:Cement Mix?
x+20(.25)=.40(x+20) x+5=.40x+8 Subtract .4x from both sides: .6x+5=8 Subtract 5 from both sides: .6x=3 Divide .6 from both sides: x=5 5 pounds of pure cement.
