For typical removal jobs on graffiti and other paint: Apply several coats of VANISH by brush, broom or spray onto the graffiti
and allow several minutes dwell time between coats at least, but the longer you can leave it on the graffiti as a wet mess,
then the better results and easier it will be to rinse away (just like soaking a burnt saucepan overnight). Agitate with a soft nylon brush between coats and rinse with a pressure washer, or scrubbing brush and water.
The main thing is patience. Paint removal can be tedious if you try to rush things. After all, you only want to do this job once, if possible.
Ideally use 1500 - 2000 psi with a 15º or 25º fan jet at about 6 inches from the surface. Do not blast or use ‘turbo’ type
nozzles which risk doing damage. When rinsing dissolved graffiti with a pressure washer, try to remove a LITTLE of the graffiti from the bottom of the tag
without wetting the whole area. If satisfied, then proceed to full scale. Wash the whole area from top to bottom.
Remember If the remover has not done its job then no amount of ‘blasting’ will fix the problem. Failures are usually a result of not flood coating adequately and not leaving product on long enough
and cannot be resolved by blasting too close or at higher pressures.
For removing carpet and tile glue.
Apply VANISH and leave on as long as needed. Scrape up as much dissolved glue as possible before pressure washing with hot water.
