Instructions for balancing concrete

Again and again it happens that parts break out of a concrete component. On floor areas, you can edit and balance these locations accordingly. But also concrete floors, which are not flat, often need to be compensated accordingly. Below you will find instructions on how to compensate for such concrete surfaces.

Various reasons to balance a concrete floor

Whether the builder who wants to implement his own services or the home renovator who wants to repair his concrete floor or screed after many years - the reasons for balancing concrete are manifold. On walls and the ceiling, you have to work with putty and restoration mortar in appropriate consistency. For concrete floors there are numerous products available, which you can also combine:

  • putty
  • Renovated concrete or mortar
  • Leveling and leveling screed
  • conventional leveling screed

Possible preliminary work before balancing

Depending on the extent of the damage, it may make sense to fill in deeper areas first with putty. But stay below the ground level so that you can process leveling compound later.

Other pretreatments that may be required

It may also be necessary to pre-roughen the concrete surface in advance. You can grind the concrete for this purpose. Use grinding machines, which you get with every well-stocked tool rental.

Step-by-step instructions for leveling concrete

  • Primer for the concrete or the concrete floor
  • Putty or restoration mortar
  • Primer for putty (on putty)
  • Leveling compound or floating screed
  • mortar bucket
  • drilling machine
  • mixing paddle
  • notched trowel
  • squeegee
  • spatula
  • trowel
  • trowel

1. Prepare the Underground

Check the damaged areas on the concrete to see whether more parts are easily removable and remove them. Then the entire floor has to be cleaned. The concrete must be free of dust and dirt, but also free of grease and free of other materials (tile adhesive, adhesive strips of carpets, etc.)

2. Prime the concrete areas to be filled

Now the places are primed, which should be filled afterwards. Follow the instructions for use of the manufacturer.

3. Fill in the deeper damages

Now the deeper damage is filled up with putty. Make sure that you always stay slightly below the actual soil level, so that the floating screed or the leveling compound can later spread out optimally.

4. Prime again

After the putty has cured, it is coated with primer again. It may be necessary to coat the entire concrete with a suitable primer. Then wait again until the primer is dry.

5. Balance concrete with leveling compound

Now the leveling screed is touched. Spread the liquid screed on the floor. Use a water slide for this purpose. Distribute the liquid screed as required by the manufacturer. Now you have to wait until the mass hardens. This can take several weeks.

6. Further processing of the concrete floor

Finally, if the floor screed has hardened accordingly, you can continue working on the floor, for example laying tiles, painting the concrete or laying out a carpet. Keep in mind that you must continue to apply a concrete surface that was previously only treated with leveling or floating screed. Leveling and floating screed is not intended to remain permanently unprotected.

Tips & Tricks

Not always you can balance concrete immediately as described. Not infrequently there is also a moisture damage or the concrete has far more damage. Then you must first repair the concrete before you can start balancing.
