Bona AmberSeal is a non-yellowing, poly-tone waterborne sanding sealer that provides an oil-based look to hardwood floors. Can be used with all Bona waterborne finishes over both stained and unstained floors.

Bona waterborne wood floor sealers offer excellent abradability, fast dry times, and reduced potential for side bonding and tannin bleed. They are non-flammable and virtually odorless sealers.

  • Specially formulated to provide an oil-based look
  • Reduces tendency for side bonding
  • Seals the wood, preventing the finish from penetrating
  • Product can be applied with a T-bar or roller
  • Fast drying – 2-3 hours

For Professional Use Only

Directions for use


  1. Sand and prepare floor using accepted industry association methods.
  2. For a stained floor, make your final cut with 80 to 100-grit paper, then multidisc with 80 to 120-grit paper. For an unstained floor, make your final cut with 80 to 120-grit paper, then multidisc with 120 to 150-grit paper. This burnishing will reduce the amount of grain raise.
  3. Use a Tampico Brush on a buffer and vacuum thoroughly.
  4. Tack with a dry Bona® Microfiber Cleaning Pad or cloth.
  5. Apply Bona Finishing system.


Apply 1-2 coats of Bona AmberSeal and 2 coats of a Bona waterborne finish. Bona AmberSeal minimizes sidebonding and grain raise, provides a build layer and prevents the finish from penetrating into the wood surface. Visit for additional product and application information.


NOTE: Use a clean applicator for sealer and a separate clean applicator for finish.


SHAKE WELL BEFORE USING. DO NOT THIN. As a best practice, double strain the finish by wrapping a fine mesh paint strainer or nylons around the supplied filter. Insert into bottle and trim off any excess material.


  1. Pour a 6˝- wide line of sealer along the starting wall. Go with the grain of the wood.
  2. Using a pre-dampened Bona floor coater, draw the floor coater forward with the grain of the wood, moving the finish toward the opposite wall. To maintain a wet edge at all times, hold the floor coater at a snowplow angle.
  3. At the end of each run, turn the floor coater and pull it toward you through the puddle; then pad out the floor coater parallel to the wet edge.
  4. Feather out all turns. Do not push too hard or too fast to avoid drips flying off the floor coater.
  5. BE SURE YOU ARE USING THE RECOMMENDED COVERAGE OF 400-500 SQ. FT. PER GALLON. DO NOT SPREAD TOO THIN. Uneven coverage can cause blotchhiness or color variance. Certain species may require a second coat to achieve desired appearance.
  6. Allow the first coat to dry 2-3 hours. High humidity and/or low temperature conditions will extend the dry time (recommended conditions of 65-80˚F/40-60% relative humidity).
  7. For smoothest results before final coat, see Intercoat Abrasion. At a minimum between
    coats, vacuum and tack thoroughly with a Bona Microfiber Cleaning Pad (dry or slightly dampened with water).


It is not necessary to abrade Bona AmberSeal unless more than 48 hours has passed since the previous coat was applied. However, for smoothest results, abrade Bona AmberSeal using 1-2 (stacked) Bona Conditioning Pads and 1-2 Bona Diamond 180 to 240-grit abrasives. Thoroughly clean abraded floor using Bona PowerScrubber OR vacuum and tack with Bona Microfiber Cleaning Pads (dry or slightly dampened with water).


Application tools should be thoroughly cleaned with water and stored in an airtight container.
