Repair and coat a damaged concrete floor

CONCRETE FLOOR REPAIR AND COATING

Products for repairing and coating a damaged concrete floor

A damaged concrete floor needs more than a new colour coat. Loose old coating, weak edges and absorbent repair areas have to be dealt with first, so the Mipa primer and epoxy floorcoat can form a stable surface instead of hiding the problem.

What do you need to repair and coat a damaged concrete floor?

Old coating removal

Mipa Quick paint stripper and Mipa Paint Stripper Spray help loosen stubborn old paint layers before the mineral floor is rebuilt.

Epoxy seal primer and repair support

Mipa EP 150-70 2K-EP Sealant primer colourless seals prepared concrete and supports small fissure or reprofiling work according to the technical information.

Solvent-free high-build floorcoat

Mipa EP 275-70 gives a dense 2K epoxy finish for mineral floors after weak coating and damaged areas have been removed or stabilized.

Waterborne epoxy floorcoat

Mipa WEP 2300-50 is a semi-gloss interior 2K epoxy floorcoat for prepared mineral surfaces, supported by WEP 9300-25 hardener and WBS deionised water.

How to repair and coat a damaged concrete floor

  1. 1
    Remove loose coating

    Strip or mechanically remove failing paint, flaky edges and areas that no longer grip the concrete.

  2. 2
    Clean and profile the repair area

    Degrease, abrade and vacuum the surface so dust and residue do not sit between the concrete and the new coating.

  3. 3
    Seal and rebuild weak spots

    Use Mipa EP 150-70 on prepared mineral areas where a sealed epoxy base is needed before the floorcoat.

  4. 4
    Apply the chosen floorcoat

    Coat with Mipa EP 275-70 or Mipa WEP 2300-50 in controlled sections, respecting the stated mixing and pot life rules.

  5. 5
    Let the repair cure fully

    Avoid early loading on repaired zones, because fresh epoxy needs curing time before it can resist traffic and cleaning.

Which repair and coating products should you choose?

Strip first when coating fails

Use the Mipa stripper format that fits the old coating area before trying to build a new epoxy surface.

Prime repaired concrete

Use Mipa EP 150-70 where exposed or absorbent mineral areas need sealing before the visible floorcoat.

Match coating to the room load

Use Mipa EP 275-70 for a heavier epoxy build or Mipa WEP 2300-50 for a waterborne semi-gloss floorcoat in interior spaces.

Technical details

  • Mipa WEP 2300-50 is a waterborne 2K epoxy floorcoat for metallic and mineral substrates in interior use.
  • Mipa WEP 2300-50 uses Mipa WEP 9300-25 hardener at 4:1 by weight or 3:1 by volume, with Mipa WBS deionised water as the specified thinner.
  • At 20 °C, Mipa WEP 2300-50 has a pot life of about 3 to 4 hours and becomes resistant to mechanical stress after about 3 days.
  • Mipa Quick paint stripper has a paste-like consistency for old coating removal, while Mipa Paint Stripper Spray is useful for smaller spray-applied removal work.
Practical suggestion

Do not coat over a weak edge. A small patch of failing paint left under a new epoxy layer can become the first point where the repaired floor opens again.
