In This How To Video, learn How To Repair a
concrete step, or a set of cement stairs
Once you have the rebar in place your ready to start forming..
Most step repairs, will be done by using a 2 x 8 board.. these are used in pouring steps most of the time, and represent
the usual height of a step. So get your boards and cut them to length. After your boards are cut lean them snug against
the step eyeball a straight line or use a t in order to your agles right. Once your boards are set in the right position,
screw the boards together at the corners.. this gives your boards more strength and helps to insure that your concrete
wont blow the corner out when you are placing it in the the damaged step area.
After you have your boards in place you will need to kick them.. and no not with your feet. kicking a board is the
process by which you either use pins or lay something against the board in order to keep it from moving.. this is to
insure the weight of the concrete does not move your form boards. You can use many things to keep your boards in
place... you can use stakes or pins, that you drive down into the ground by the concrete board.. this is usually what
proffestionals do, but you probably dont have pins or stakes available.. so you can use bricks, blocks, or sand bags..
these will do the trick as well. We will use block for this demonstration.. lean your block at an angle to make sure that
you are getting the full effect of the block.
see image below.
The process repairing a single step, or many stairs are basically the same..
for badly damaged stairs the following process works a little better.
Step one, Clean the damaged steps that are to be prepared.. This can be done in several ways
You can do this by using a broom and sweeping away the loose debris.. You can do this by using
a wire brush and brushing the damaged area to get all loose debris or dirt off of the surface..
Or my preffered method is to use a power washing on a low setting..
Please note: excessively damaged steps can just keep shedding concrete so you will need to
stop the cleaning process if you notice too much of the step coming off. Get the surface off, and try
to get to a semi solid concrete base. After you have cleaned the steps, you will be ready to move
to the next step. If the step is missing a good portion of the step it is advisable to use some kind
of anchor in the step to help keep the repair in place. The anchor can be a rebar, or a concrete
anchor.. most people use rebar. To prepar to place the rebar drill into the step using a hammer
drill on low hammer cycle.. it is important to use care on your deteiorating steps or you can do
more damage. so go slow and let the drill do the work. you will want to get into the concrete about
3 to 4 inches.. stay away from the edge of the concrete when drilling or you can cause a chunk of
concrete to actually break loose. One you have your holes drilled you will be ready to put in your
short 5" rebar or anchor ties. These can be shoved into the holes, but I like to use a fast set
cement repair agent in the holes first, to keep the rebar solid in place.... If you do not have a fast
set concrete/cement anchor repair agent available then just make sure to get some of the
concrete worked into the hole as much as possible when pouring the step back.
Once your forms (boards) are in place you will be ready to pour your concrete into the forms.. in the damaged step
area. Hopefully you have settled on a concrete product to use by now... we would recommend a fast set repair product.
To help adhersion to the step it is a good idea to keep the damaged area of the step damp while you are pouring in
your concrete. Get your concrete ready and begin mixing... if you need help on mixing concrete please see our section
on mixing concrete here.
Once your concrete is mixed up you can pour it into the forms., you will want to get the concrete level with the top of
where the step use to be. pour in your concrete and use a trowel to push it into the damaged area, keeping the pressur
off of the board and putting it onto the step. as you continue to pour your concrete into the step if you notice the board
starting to move or slip then lay more blocks on the boards and wait for the concrete to set up a bit before you mix any
more... you can use a shovel to dump a shovel full of concrete at a time into the step area, or you can use buckets and
pour a bucket at a time into the step area. Go slow, use a rubber mallet or hammer and slighly tap on the board every
time you pour some concrete around the board... this helps get all the air pockets out and means less holes to fill when
the form board is removed... and once the concrete is level with the form board finish and edge your concrete.. Repeat
the process for every step that is damaged, but you may want to let the bottom step dry completely before moving up to
the next step. We recommend letting your concrete cure/dry completely before removing the form boards.. you may
need to cover or fill any holes that are left on the sides or face of the steps when you remove the form board.
