Directions

Where to Use
TM-4 Heavy Duty Remover is recommended to remove coatings from wood, plaster, glass and all metal surfaces. Can also be used to remove finish from antiques, marine brightwork or any other sensitive surfaces.

Before you Begin
• Read all cautions on side panel carefully.
• Use caution when opening can as remover may build up pressure through temperature changes.
• Hold rag over cap until pressure is released.
• Protect hands with plastic (polyethylene or neoprene) gloves.
• Use old, inexpensive or throw-away bristle brush for application.
• For best results, use when temperature is between 60° and 85°F. Apply away from strong breezes and hot sun.
• Do not use on linoleum, rubber, asphalt or other synthetics.
• TM-4 may dissolve some fiberglass gel coats. Test in an inconspicuous area.

To Apply
• Pour a small amount of TM-4 into an open container.
• Use a paint brush to lay on a generous coating. Do not brush out as you would paint, as this will destroy the evaporation retardant. Be sure surface remains wet.
• Allow TM-4 to soften the finish; most paints and finishes will blister in 10 to 15 minutes. Thick layers may require up to one hour.
• Old finish is ready for removal when it blisters, wrinkles, or can be lifted easily with a flat scraper. If a finish is particularly stubborn, repeat application.

To Remove
Scrape-Off Method: Use a round-cornered scraper, steel wool and/or burlap cloth to remove old finish. Test scrape in a small area to be sure finish is ready for removal. If finish removes easily, continue scraping project gently in the direction of the wood grain. Be careful to avoid gouging the surface. Repeat application if finish is particularly stubborn. To remove stubborn spots, rub light with fine steel wool that has been dipped in TM-4. For deep carving and recesses use a toothbrush, fine wire brush or a pointed stick to remove finish. To complete cleaning, use fine steel wool dipped in TM-4 and wipe with the grain. Wipe surface with clean cloth, then let dry.

Water Wash-Off Method: Rub prepared surface with wet toweling, burlap or fine steel wool and water to form a creamy mixture. Use a wet toothbrush to get into carvings or grooves. Rinse off mixture with wet cloth or sponge. Flush with water from a hose when possible and wipe dry. Plywood or veneers should be dried promptly.

To Remove Finish from Antiques, Marine Brightwork or any Sensitive Surface:  Apply TM-4 liberally, then wait approximately 30 minutes. Agitate remover and finish with stiff natural bristle brush dipped in water. After a mixture is formed, remove it with a wet clothe or sponge.

To Remove Stain: After TM-4 has softened the finish, allow it to remain on the surface approximately 30 to 40 minutes. Agitate with stiff natural bristle brush dipped in water. After a mixture is formed, remove it with a wet clothe or sponge. When dry, sand surface with steel wool or sand paper until smooth. Remove sanding dust.

To Refinish
After using any of the removal methods mentioned above, allow the surface to dry thoroughly. Be sure all dissolved residue is removed and the surface is completely clean and dry. Sand lightly in the direction of the wood grain before applying the new finish.

Removing Old Finishes

Removing paints and clear finishes can be a tedious, dirty job. Thankfully, Old Masters® top-grade removers quickly strip away previous finishes with ease. Use the following section for typical removal instructions.

Apply a liberal coat of remover to project surface with a bristle brush, brushing in one direction only. Do not brush out as you would paint – as this will destroy evaporation retardant.

  1. Allow the remover to soften the finish, approximately 10-15 minutes depending on the number of layers of the old finish. The old finish is ready for removal when it blisters, wrinkles or can be lifted off easily with a flat scraper.
  2. To remove finish, you can use a round-cornered scraper, steel wool and/or burlap cloth to remove old finish.
  3. If finish is particularly stubborn, remove loose residue by scraping, then repeat application.
  4. To complete cleaning on most projects, use fine steel wool dipped in TM-1 or mineral spirits and wipe with the grain.
  5. Wipe surface with clean cloth, then lightly dry.
  6. Once surface is completely dry, sand lightly in the direction of the woodgrain before applying the new finish.

(Do not use on linoleum, rubber, asphalt or other synthetics.)

WARNING! If you scrape, sand or remove old paint, you may release lead dust. LEAD IS TOXIC. Contact the National Lead Information Hotline at 1-800-424-LEAD or log on to www.epa.gov/lead.
