Do I need to abrade the sealer coats before putting down my first finish coat?
Several reason why you may need/want to abrade, prior to finish coat applications on a sport floor:
- If the surface contain debris or minor imperfections, then abrasion suggested for smoothness or blending (Bona Conditioning Pad or used 120-150grit screen);
- If it's been more than 48 hours since the last application of sealer, then abrade with Bona Conditioning Pad to maximize adhesion;
- If you're getting ready to apply CourtLines Paint, then abrade with Bona Conditioning Pad to maximize adhesion for paint to sealer coat (may also want to do this if applying SuperSport Paint, but not required);
- Depending on the paint used (see product directions), painted areas may need to be abraded with Bona Conditioning Pad (then thoroughly cleaned/tacked) to maximize adhesion of top coats;
- If you're applying oil-based finish over the top of a waterborne sealer, then abrade with Bona Conditioning Pad to maximize adhesion of oil-based products;
- Otherwise, if none-of-the-above are present, then no need to abrade prior to applying first finish coat to sealer.
**Best Practice: It's never a bad idea to give the whole floor (sealer and paint, if applicable, applied) a final abrasion pass using Bona Conditioning Pads (320grit); then thoroughly clean (Tampico brush; then auto-scrubber or Bona Power Scrubber w/water; final wet tack to remove any dirty streaks); let dry; and apply your finish coats for ultra smooth results!
