Surface Preparation: The Foundation of a Lasting Repair

Nie matter how high-quality your patching material, a naprawa will fail if thee substrate is note propertily prepared. Adhesion requires a clean, sound, and propertily profiled surface.

Cleaning andDebris Removal

Start by removing all loose concrete concrete, dirt, oil, graase, paint, and curing compounds. A wire brush or crumper works for small areas, but a pressure washer is far more efficient for larger jobs. For stubborn contaminats like oil bars, use a commercial defaser or a muriatic acid solution (follow safety contations and neutrize afterward). Allow thee surface te to dry slightly; you want damp but nwet wet whewheing most menir materials.

Cementitious Patching Compounds

Traditional cement- based patches are approablee for small, non-structural repair in low- traffic areas. They ary incoprisive and esy to work with, but they shrink slightly during curing andd have limited flexibility. Mix only as much as you can appley in 15- 20 minutes.
