How is TCI 503 HD applied?
First cool the surface to be cleaned. Early mornings or evenings are best. Apply TCI 503 HD, right from the container, using a pump-up pressure sprayer. Start from the bottom up and work in a manageable sized area. Brushing is optional. Allow TCI 503 HD to work about 2 minutes. Remove using a high pressure 2800 psi COLD water washer. Start from the bottom up. Rinse completely. Watch for overspray and don’t let TCI 503 HD dry on the surface.
