Beautify old washed concrete slabs in different ways

Washed concrete slabs hit the taste of many people in the 1960s and 1970s. Today, the enthusiasm has dropped significantly and many people are thinking about beautifying the characteristic structure and look. From turning the plates over the complete filling of the structure to dressing up the possibilities are enough.

Work up the shine

Anyone who thinks of washed concrete slabs usually has in mind the coarse pebble finishes with grain sizes of eight to 16 millimeters. Depending on the stone selection, in most cases ordinary river gravel, the textures in gray and black tones meander across the surfaces. In most cases, old washed concrete surfaces have lost any shine.

If the washed concrete look is to be preserved, the thorough cleaning of the panels and the subsequent processing with a wire brush and steel wool can restore the gloss. A pressure washer removes dirt films and green growth. The individual pebbles can be scratched, which makes the absence of shine. With a fine wire brush and household-grade steel wool, as used for cleaning cookware, the pebble surfaces can be sanded smooth again. The overall effect depends on the thoroughness of the laborious work.

"Leveling" the surface

A common alternative is to "make invisible" the washed concrete by filling the cavities and creating a flat surface by plastering the washed concrete slabs. With a conventional plaster structure and optionally additional lime mortar as filler can be made of washed concrete surface any decorative plaster surface.

Smooth plaster allows a subsequent brushing of the washed concrete slabs. An alternative is the direct brushing of the washed concrete without prior plastering. With plastic resins or garage floor coatings thick paint jobs can be applied, which can be spiced up with additional fillers such as colored small stones, mica or sand.

Turn around or dress up

If the washboard condition allows it, turning over particular floorboards is in some cases a viable option. The mostly smooth backs can then be finished like smooth concrete surfaces. Since washed concrete slabs can be drilled, dressing with plastic or wood is also quite possible. Wooden planks can be mounted on stilt systems, which assign the washed concrete the function of a fixed and invisible ground.

Tips & Tricks

If, for example, you remove every second plate in a checked pattern from a path made of washed-out concrete slabs and sow ornamental or mossy lawns on the open areas, the rest of the slabs receive a completely new optical effect.
