GBC use several techniques such as controlled safe chemical removal, this requires careful removal by applying a chemical that removes the graffiti keeping the surface intact. This procedure works well with signage, however prolonged removal will eventually damage the substrate.
Painting out graffiti: this option is the fastest and less costly than a chemical wash. When painting over graffiti on lighter colours we recommend and use stain killing undercoats, this procedure takes longer however the finished product is far superior.
We specialize in removing spray paint from brick surfaces, this is a chemical process that softens the paint which we then remove water blasters. Check out our photo gallery for samples.
