Surface Preparation
- Sand and prepare floor using accepted industry association methods.
- 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.
- Use a Tampico Brush on a buffer and vacuum thoroughly.
- Tack with a dry Bona® Microfiber Cleaning Pad or cloth.
- Apply Bona Finishing system.
THE BONA CLASSICSEAL FINISH SYSTEM
Apply 1 coat of Bona ClassicSeal and 2 coats of a Bona waterborne finish. Bona ClassicSeal is not recommended for use over Bona DriFast® Stain. Bona ClassicSeal minimizes sidebonding and grain raise, provides a build layer and prevents the finish from penetrating into the wood surface.
RECOMMENDED APPLICATORS
NOTE: Use a clean applicator for sealer and a separate clean applicator for finish.
MIXING INSTRUCTIONS
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.
SEALING
- Pour a 6˝- wide line of finish along the starting wall. Go with the grain of the wood.
- 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.
- 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.
- Feather out all turns. Do not push too hard or too fast to avoid drips flying off the floor coater.
- BE SURE YOU ARE USING THE RECOMMENDED COVERAGE OF 500-600 SQ. FT. PER GALLON. DO NOT SPREAD TOO THIN. Uneven coverage can cause blotchhiness or color variance.
- 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).
- 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).
INTERCOAT ABRASION
It is not necessary to abrade Bona ClassicSeal unless more than 48 hours has passed since the previous coat was applied. However, for smoothest results, abrade Bona ClassicSeal using 1-2 (stacked) Bona Conditioning Pads and 1-2 Delta Sheets as needed. Thoroughly clean abraded floor using Bona PowerScrubber OR vacuum and tack with Bona Microfiber Cleaning Pads (dry or slightly dampened with water).
CLEAN-UP
Application tools should be thoroughly cleaned with water and stored in an airtight container.
