Investing in a new wood floor or a new sand and refinish of an existing wood floor is a unique and rewarding way to enhance any space in the home. The result should be aesthetic and natural but should also be simple to clean and maintain if done properly. Unfortunately it is also easy to do it wrong with potentially really bad consequences without the right information.
CURING PROCESS
For a site finished wood floor, after the last coat of finish is applied the curing process begins. The new finish starts out vulnerable and slowly develops the toughness we want. The first stage is drying, once the finish is dry any dust or debris that settles on it will not get stuck on the finish and will be harmlessly swept away. The finish off gasses until it achieves a full cure, meaning it is as hard and tough as it will ever be. Low humidity and air movement accelerate this process, but the timing also depends on the type and brand of finish.
The normal recommendation is that after it has dried to walk on the floor in socks only for the first 48 hours. After that time you can begin to move furniture that has legs (tables, chairs, etc) onto the finish but you should use the felt adhesive 'floor protectors' on everything. Definitely use them for chairs or things that will slide about. You may cover the floor to do light work but it is imperative to use a clean covering and take it up at the end of the working period since the finish needs air exposure for proper curing. Do not put anything that will cover an area (like boxes, mats, etc) permanently on the finish until after full cure.
CLEANING
Spills should be wiped up as soon as possible. Routine cleaning to sweep up dirt and grit with a dry dust mop or soft bristle broom, or even vacuuming with a hard surface vacuum cleaner, will go a long way toward keeping the wood floor finish in good shape. The vacuum may be the best bet for older floors with gaps or bevels.
For penetrating oil finishes that to some extent rely on wax additives, you must use their brand of cleaners which are engineered to not damage the oil. In fact the typical advice in general is to use the same brand of cleaner with whatever brand of finish was used. But apart from penetrating oils the main point to remember for cleaning the floor is to use cleaners approved for finished wood floors because they won't leave any kind of wax or oily residue on the surface, which could inhibit bonding of future maintenance coats of finish.
MAINTAINING THE FINISH
This refers to procedures we do above and beyond normal everyday cleaning to add some protection to the existing finish. It is similar to the initial process of building up a new finish on the wood floor but the essence of the process is whether, or to what extent the new application will bond to what's there. A good bond is for the most part dependant on if a proper cleaner has been used before.
For film building finishes our process is to clean the existing wood flooring with a product that not only deep cleans the surface but lightly softens it to help the new coat bond to the existing finish. After this treatment we lightly abrade the surface with a fine grit, thoroughly clean it and apply a new coating. For penetrating oil finishes the process is similar except instead of applying another coat of finish after the deep cleaning the wood gets reoiled. It can be spot applied or done to the entire floor.
Most all do-it-yourself wood floor finish maintenance products are to be avoided. Usually they contain acrylic and are labeled as rejuvenators or restorers, or wood floor polishes. Most people are unhappy with the results and they can leave the floor looking streaky (they might look good for a little while). And by far the biggest issue is they make it so we can't recoat the floor, because getting another coat of the finish to bond to the acrylic will be tricky if not impossible.
RUGS
Walk off mats at entrances can help keep dust and grit off the wood floor. If a rug pad is used under any rugs, it is important not to use the cheap PVC (polyvinyl) pads. They can react with the finish and potentially permanently discolor the floor. 100% natural rubber is good as well as 100% felt, although the felt rug pads don't help for slipping around and so should only be used on large rugs. Felt and rubber hybrid pads offer the best cushioning and are still good non slip rug pads.
One other thing about rugs is that the finish or even the wood itself will darken over time due to light exposure, or it can bleach out from UV exposure from a nearby window. If this happens where a rug has laid in the same spot for a long time, there can be a darker or lighter rectangle in the finish. Moving rugs around can help with this problem. Using a clear finish with UV inhibitors can help but the phenomenon still occurs.
SUMMARY
Hopefully this helps to make your wood floor finish age gracefully. Other things that may help: keep dog claws trimmed, avoid high heels on the wood, watch for a pebble stuck in boot lugs.
Here is a quick recap of the main points:
- Freshly coated wood floors need time to cure before use, low humidity and air movement helps
- Once the new finish is dry wait 48 hours for shoe traffic and then you can move furniture with legs onto the finish, use felt floor protectors
- Wait for full cure for rugs or anything that covers an area
- If you cover the floor to work over it take up the covering to allow air exposure for curing, until the finish is fully cured
- Don't wet mop the new finish until fully cured
- For regular cleaning immediately wipe up any spills and routinely sweep up dust and grit
- Only use cleaners approved for finished wood floors and for penetrating oil finishes use the same brand of cleaner as the finish
- Have us back for maintenance before the finish breaks down anywhere, which could be in 5 or 10 years for film finishes or 3-5 years for penetrating oil finishes, possibly sooner depending on level of wear and tear
