Most spray paint graffiti is very easy to remove from trees, and it can be done without poisoning or permanently damaging the appearance of the tree.
Brush on Bare Brick, Stone & Masonry Graffiti Remover and agitate with the brush as you apply.
Depending on the type of graffiti, you may need more than one coat and a little dwell time between coats to ensure the spray can is fully dissolved before rinsing.
Once the graffiti has dissolved, use a pressure washer to rinse, taking care not to blast too close to the tree so as not to remove any bark or etch the surface.
Using a yellow 15° tip, or green 20° tip, stand back as much as possible and keep the wand moving along the tree to avoid damage, as seen in the photos.
Alternatively, a stiff-bristled nylon scrub brush and a bucket of water can be used to rinse the tree’s surface.
3 Golden Rules
1) If graffiti is not coming off easily, you're doing it wrong! You may require a change of tact or use of another product.
2) If you can't remove a little, then you're not going to remove a lot. TEST FIRST before applying product to an entire job. This way you can determine if you’re on the right track before embarking on full scale removals.
3) If you're working hard, you're doing it wrong. Forget the scrubbing, blasting and any other abrasive measures. Put simply, either your products are working or they’re not. Any problems can be taken care of with the right technique.
