Arm-R-Seal Oil-Based Topcoats are made with the highest-quality urethane resin, making them extremely durable and long-lasting.

Formulated to be wiped on with a cloth or applied with a foam brush, this ambering finish penetrates to provide deep-down protection for that 'natural' look.

Arm‐R‐Seal is a durable, oil‐based topcoat made with high‐quality urethane resins for exceptional durability. This easy‐to‐apply finish will bring out the natural beauty in hardwoods such as Walnut and Mahogany and will amber over time.

Can you Spray Arm-R-Seal?

Arm-R-Seal can be sprayed successfully, but we prefer hand application methods because it is very easy to spray too much in one area. If you choose to spray, use very thin coats and watch for runs (large drips that run down the side of your project).

If you notice a run, immediately wipe or brush it out. If you correct a run promptly, you will not see a mark. However, dried runs can be difficult to remove.

  • Wear a mask and work in a well-ventilated spray booth.
  • Size: Small Needle Nozzle (1mm)

Can An Oil Based Topcoat Such as Arm-R-Seal Be Thinned?

Although Arm-R-Seal rarely needs thinning because of its low viscosity, it can be thinned with up to 10% mineral spirits - more than that may thin the solids content too much. Thinned Arm-R-Seal will be diluted but can be stored without risk of separation.
