Screen and Coat Worn or Dull Hardwood Floors

The screen and recoat (also called buff & coat) procedure for hardwood floors is a Screening hardwood floors cost effective method of fixing or revitalizing worn or dull floors. Instead of paying for a complete refinishing, floors can be brought back to life, but don't expect deep scratches and dings to be removed. The same holds true for removing paint that may have been splattered over the years. Frequent screen and coat applications can protect floors and postpone or eliminate the need for a complete refinishing at a later date.

How Does It Work?

Screening involves abrading the old finish on the existing floor making it compatible for applying another layer of new finish. If you've ever handled any trim painting work, the procedure is similar. A professional finisher will bring in a buffing machine and attach a special sanding screen to the bottom (seen on right). Minor surface scratches and marring from moving furniture can be removed.

Preparations. What Was Used To Clean Before

This buff and recoat procedure will not work effectively with floors that may have been maintained with oily cleaners unless a complete cleansing is done prior to the process. Often what may be required is a thorough going over with odorless mineral spirits and a fine steel wool pad that is also attached to the floor buffing machine. Loosening the buildup is one thing, removing all of the impurities that can affect a new finish bond is another. Removal should be done meticulously with clean rags. Often a going over twice will give more peace of mind.

Can We Screen Waxed Floors and Recoat?

If you're contemplating an easier finish to maintain opposed to wax this will not work. Any new finish will react with older waxes and likely to blister or peel in short time. Only a reapplication of wax and buffing will work with these types of finishes. More at the page link below on waxed finishes.

Can Newer Aluminum Oxide Floors Be Recoated?

Original aluminum oxide floors cannot be successfully screened and coated. However, since these floors became popular, prefinished flooring manufacturers changed the method in which the finishes were applied. Instead of the aluminum oxide finish layers being on the surface of the finished product, they began to sandwich them under finishes that are compatible with screening. If in doubt of the original product specifications a call to the manufacturer would be advisable.

How Long Does It Take?

Newer water and oil based finishes will take the same amount of time to apply, with the oil based taking longer to dry and cure. Time involved for a 400 square foot, square room with furniture removed and ready to go will take approximately three hours.

Other Notes

For more challenging and lesser known finishes it's best to consult with a professional floor finisher that has the experience needed to better assess your situation.

Peeling Finish

Question: Hi, thanks for a fine site. We have a question about peeling finish on our new hardwood floor in the San Diego area. It was fine up until six months ago then the peeling started near the kitchen and just got worse after that. The floor finisher says he can just screen and buff the floor and add new finish. Will this work?

Reply: The peeling problem may not be a simple surface issue that screening can take care of. I would suggest finding out what procedures were used to finish the floor from start to finish. Also what types of sealers and finishes were used. There may be some contamination involved that is preventing a good bonding.
