# Screening vs. Sanding Hardwood Floors: Which Do You Need?

![Screening vs Sanding Hardwood Floors](https://www.national-floors.com/client-support/hardwood-flooring-q-a/images/screening-versus-sanding-floors.webp)

At that point, homeowners are often faced with two very different options: **screening and recoating the existing finish or completely sanding and refinishing the hardwood floor.**

The difference is important. Screening is primarily a maintenance procedure performed on the existing finish. Sanding removes the old finish and exposes the hardwood underneath. Choosing the correct process depends on the actual condition of the floor, not simply its age.

## What Is Hardwood Floor Screening?

Screening is a light abrasion of the existing floor finish. A floor buffer and abrasive screen are used to lightly abrade the surface so another compatible coat of finish can properly bond to it.

The important thing to understand is what screening **doesn't** do.

Screening does not sand the hardwood back to bare wood. It cannot remove deep scratches, pet stains, water damage or discoloration that has penetrated into the wood. It also cannot change the existing stain color.

Think of screening as maintaining the protective finish that's already covering the hardwood rather than restoring the hardwood itself.

## When Is Screening a Good Choice?

A screen and recoat can be a good option when the existing finish has become dull or lightly scratched but remains intact.

The key is catching the floor early enough.

If normal foot traffic has only affected the surface of the finish, screening can prepare that finish for another protective coat. This can extend the life of the existing finish and postpone the need for complete sanding and refinishing.

However, once the finish has worn through and exposed bare wood, screening cannot correct the damage underneath. Dirt, moisture and normal traffic can begin affecting the wood itself.

This is why we don't recommend choosing screening simply because it costs less. First determine whether the floor is actually a candidate for it.

## There Is Another Important Issue With Screening

Before applying another coat of finish, we need to know what has been put on the floor previously.

Wax, polishes, certain cleaning products and other contaminants can interfere with adhesion. If the new finish cannot properly bond to the existing coating, it can peel or fail.

A floor that looks like a simple screen-and-recoat project may therefore require additional evaluation before another finish is applied.

Proper preparation is every bit as important as applying the new coat.

## When Does a Hardwood Floor Need Sanding?

When wear or damage extends beyond the existing finish, it's usually time to consider complete [hardwood floor sanding and finishing](https://www.national-floors.com/client-support/hardwood-flooring-q-a/index.php?Itemid=103).

Professional sanding removes the old finish and stain and takes the floor back to clean wood. This gives us an opportunity to address many of the problems that screening simply cannot correct.

Full sanding may be appropriate when:

- The finish has worn through to bare wood.
- There are deeper scratches or gouges.
- Pet stains or other discoloration have penetrated the surface.
- The existing finish is badly damaged or failing.
- Previous repairs need to be blended into the surrounding floor.
- The homeowner wants to change the stain color.
- The floor has significant uneven wear.

After the old finish has been removed, repairs can be made where necessary. The floor is then progressively sanded, stained if desired and protected with a new finish system.

The result isn't simply another coat over the existing floor. It's a restoration of the hardwood surface itself.

## Screening vs. Sanding: The Simplest Difference

**Screening works on the finish. Sanding works on the wood.**

That's the easiest way to understand the difference.

If the hardwood underneath the finish is still in good condition and the existing coating is suitable for recoating, screening may be all that's necessary.

If damage has reached the wood, the existing coating has failed or you want to substantially change the appearance of the floor, sanding provides a much more complete restoration.

Using the wrong process can also be false economy. Screening a floor that really needs sanding may temporarily improve the sheen without correcting the underlying problems. On the other hand, completely sanding a floor that only needs a maintenance coat removes wood unnecessarily.

## What About Water-Damaged Hardwood?

Water damage requires a different approach.

Cupping, crowning, dark staining or movement between boards can indicate a moisture problem. Before sanding begins, the source of the moisture needs to be identified and corrected.

Sanding a wet or unstable hardwood floor doesn't solve the cause of the problem.

The floor may need time to dry and return to a stable moisture condition before we can determine what damage is permanent and what can be repaired. In some cases damaged boards may need to be replaced before the entire floor is refinished.

The same basic principle applies to termite damage, broken boards and other structural problems: **repair the problem first and refinish the appearance second.**

## Can Engineered Hardwood Floors Be Sanded?

Sometimes.

Unlike solid hardwood, engineered flooring has a hardwood wear layer over a manufactured core. The thickness of that wear layer determines whether there is enough hardwood available for sanding.

Some engineered floors have enough usable hardwood to be professionally refinished. Others have very little material available above the tongue-and-groove system and cannot safely tolerate aggressive sanding.

Before sanding an engineered floor, its construction and remaining wear layer should be evaluated. Guessing can permanently damage the flooring.

## Older Hardwood Floors Can Still Have Plenty of Life

One of the advantages of traditional solid hardwood flooring is its ability to be restored.

Many older Bay Area homes still have their original oak floors. Those floors may look badly worn after decades of use, but appearance alone doesn't tell us whether they need replacement.

We've seen old hardwood floors hidden beneath carpet or covered by years of worn finish that look dramatically different once professionally sanded.

As long as sufficient hardwood remains and the floor is structurally sound, refinishing can often give an older floor many more years of useful life.

## The Finish Matters Too

Whether the floor is screened or completely sanded, the new finish becomes its protective surface.

The correct finish depends on the hardwood, desired appearance and how the home is used. Sheen also matters. Satin and matte finishes generally make everyday scratches and normal wear less noticeable than high-gloss finishes.

Once refinishing is complete, proper [hardwood floor care](https://www.national-floors.com/client-support/hardwood-flooring-q-a/index.php?Itemid=205) can help protect the new surface. Avoid waxes and inappropriate cleaning products that may not only affect the appearance of the floor but also create problems when another maintenance coat is needed in the future.

## Don't Wait Until the Finish Is Gone

If your hardwood floor is simply losing its sheen and showing light surface wear, screening and recoating may extend the life of the existing finish.

If the finish has already worn through, the wood is damaged or stained, or you want to change the floor's color, complete sanding and refinishing is usually the more appropriate process.

National Floors has specialized in hardwood floor sanding and refinishing throughout the Bay Area for decades. Before recommending either process, we look at the condition of the finish, the hardwood underneath it and what you're trying to accomplish.

**The goal isn't to sell the larger job. It's to do the work the floor actually needs.**
