  •  Door Refinishing - removes chalk (oxidized paint), grease and grime in preparation for refinishing roll-up doors*
  •  Powerful Cleaning - dilute as needed for tough cleaning jobs (product is usually not diluted when used to strip chalk. See note below.)
Coverage: When use full strength for heavy chalk/oxidation removal in preparation for refinishing 1 gallon is generally enough to remove heavy chalk on up to 10-12 8' x 8' doors. Your actual usage may vary depending on how you apply the product.

Note: When used for to remove chalk for refinishing the product is used full strength with no dilution. Using Zap-It full strength on heavily oxidized / chalking surfaces may require repainting depending on how many layers of paint have been oxidized. Chalk or oxidized paint is essentially 'dead-paint' with the binder broken down resulting in the powdery coating. Zap-It strips off this oxidized paint. Use with caution if clear finish is being considered since repainting may be required if enough of the existing paint has been oxidized that cleaning it up leaves too thin a coat or even exposes the metal. Test on one door if in doubt.

Important: This quart contains full strength "Zap-It". DO NOT spray "Zap-It" full strength on a dry door you do not intend to refinish. It may degloss the door and will remove layers of oxidized paint. Always use on wet door. If your paint is heavily oxidized Zap-It may remove enough material to require refinishing. Review all support material prior to use. Test on a single door or small area if in doubt.

Tools

  • Garden sprayer or other pump sprayer. 
  • Very soft “RV” or auto cleaning brush on a 4 ft extension pole (deck or stiff bristle brushes are not effective in removing chalk). 
  • Extra Fine or non-abrasive synthetic steel wool pads, sometimes referred to as “Scotch Brite” pads. (Use when refinishing with a clear coat or for general cleaning). Microfiber pads may also be used.
  • Medium grit synthetic steel wool pads, sometimes referred to as “Scotch Brite” pads. This may remove paint so use only when refinishing with paint or a pigmented coating.
  • Power washer or garden hose with a high-quality nozzle for rinsing the doors.

Cleaning in preparation for repainting with Chem-Bake or Door Restore:

Brush off all loose dirt, dust and debris. DOOR MUST BE COMPLETELY DRY! With dry substrate, liberally apply diluted cleaner (per Dilution Recommendations) thoroughly wetting entire surface and keeping the surface wet with cleaner at all times while scrubbing with a soft “RV” or “car” washing brush. Spray with water as needed to keep the surface wet during the scrubbing process. Hand clean with pad at the top, sides close to the walls and other areas where the brush cannot be used effectively. Rinse thoroughly. Avoid letting the cleaning solution dry on surface prior to rinsing (allowing the cleaner to dry can leave streaks and require a re-wash of the entire door). Inspect after dry to make sure all chalk and grime has been removed. Any remaining chalk should be hand cleaned with a micro-fiber or other non-abrasive pad then thoroughly rinsed. IMPORTANT: The brush used is very important. DO NOT use “deck “, “utility”, or other stiff bristled brushes. Car or RV’s cleaning/detailing brushes work best. Softer, fuller brushes are more effective in removing chalk in combination with Zap-It Chalk & Grime Buster.
