Heritage Graffiti Remover is specifically designed for the delicate task of removing graffiti from historic and sensitive buildings. Designed to safely clean stonework, brickwork, and masonry without causing damage, this remover works effectively with minimal pressure to lift softened graffiti. It rinses easily to prevent residue of insoluble salts on masonry, making it ideal for porous stone and concrete surfaces such as cinderblock, split face block, and exposed aggregate. Suitable for natural stone types like limestone, granite, marble, and terrazzo, it also works well on painted and coated surfaces, including signs, stainless steel, trees, and most plastics.

Heritage Graffiti Remover is applied to the surface with a nylon brush, broom or pump-up sprayer, 3 times at 3 minute intervals, liberally flooding the graffiti/stain with the product. For typical graffiti, approximately three minutes after the final application, rinse using a hot or cold pressure washer (hot is best) at low pressure. If one is not available, then a stiff nylon brush and bucket of water may suffice. Agitation, as you apply this product, can be of great assistance.
Continued experience with the product will enable the user to judge how many applications are necessary for varying surfaces and particular spray cans. On older/thicker graffiti patience is the key. Keep the graffiti wet with the product, as long as possible before rinsing.
Do not blast too close, in order to remove the graffiti, as it may cause damage and will possibly only remove a small percentage more. Remember, a pressure washer in this instance is really only a quick release rinse of the dissolved graffiti, and not the primary means of cleaning. 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.
Coverage Guidelines
1 gallon of Heritage Graffiti Remover typically covers approximately 200 sq. ft. on bare brick, stone, and masonry surfaces. Coverage may vary based on the type of stain and the porosity of the surface material.
