Semi-Permanent coating

The surfaces to be protected are treated first with a penetrating sealer (permanent protection component) which prevents the paints and varnishes from penetrating deep into the substrate. A temporary (sacrificial) layer is applied and subsequently „sacrificed“ when removing graffiti. A new coat needs to be applied.

Semi-Permanent protected surfaces can be cleaned in an environmentally friendly way using hot water high pressure. Chemical graffiti removers are usually not necessary. Semi-Permanent coating is ideal for natural stone walls and is frequently used for listed historic buildings.

Technical Process

Step 1.

Semi-Permanent coating
(A. sealer and B. sacrificial layer) is applied on the surface.

Step 2.

Normal moisture evaporation through semi-permanent coating.

Step 3.

Paint is sprayed on the semi-permanent coating and is blocked at the surface by the sacrificial layer. The sealer prevents the paint from sinking deep into the substrate.

Step 4.

Graffiti and underlying coating are cleaned off with hot water high pressure. The sealer is not affected.

Step 5.

The sacrificial coating is re-applied on the affected areas.
