They are easily renewed by using a refresher to restore the shine, applying a light screen and coat with urethane and if all else fails, you have the option to sand and refinish your hardwood floors!

The process of hardwood floor sanding and refinishing may present a certain level of uncertainty for anyone who has not had first-hand experience with it.

There are many steps involved in sanding and preparing newly installed or pre-existing hardwood floors. Moreover, the refinishing process itself will present several possible options to achieve the results desired for your specific interior design concept. The following is a walkthrough provided by one of JanNet‘s specialist as to the various steps necessary to complete a hardwood floor service project.

Sanding and Preparation

Our well trained specialists begin by determining the proper grit sandpaper required and number of sanding passes necessary for each specific work site. Based on experience, the mechanics will recognize the grit needed to remove any old finish, scratches and/or embedded dirt within the wood floor. Yet still not allowing too much wood to be removed with each pass. The floor may need to be sanded two to four times depending on the age and type of finish, and the condition and species of wood being refinished. Newly installed unfinished hardwood floors will need to be sanded as well, due to slight milling imperfections and minor board edge unevenness.

We utilize flooring sandpaper all grit grades. The main areas of the floor are sanded with a large professional drum sander, while the perimeter is completed with a circular edge sander. A hand scraper is used to remove old finish from corners, bull nosing on steps or ledges and generally any small area our sanders cannot reach.

The floor is then vacuumed, and tacked (passed over with a dampened towel) to remove any dust, prior to stain or finishing polyurethane being applied.

Between polyurethane coating layers the hardwood floor is burnished with a sanding screen. The first coat of polyurethane commonly absorbs into the wood and raises the grain. This will give the dried coating a slightly irregular and rough feeling – which is perfectly normal. The dried polyurethane simply requires a ‘screening’, so the floor will be made smooth prior to cleaning and recoating again.

Types of Polyurethane

We utilize the two most common types of hardwood floor polyurethane coatings. These are an Oil Modified polyurethane and a Waterborne/Latex polyurethane.

Both of these finishes are available in Gloss, Semi-gloss or Satin sheens. The image below displays general representations of what your floor may look like when polyurethane is applied to your hardwood floor.

Maintenance Recoats / Top coating

Years after a hardwood floor are completely sanded and finished a maintenance coat is needed to sustain the floors performance and cosmetic appeal. This JanNet recoating procedure, commonly called a ‘topcoat’, will return a hardwood floor to its newly refinished condition – provided it was performed within the ample period of time necessary.

A ‘screening’ of the original polyurethane coat, with a silicon carbide sanding screen on an upright floor polishing machine, will remove any light scratches and surface dirt. This slight burnishing of the floor permits a new coating to properly adhere to the existing one. The screening process does not remove much of the existing coatings, nor does it expose the bare wood as in the full sanding procedure. It is the same as that which is performed on the last day of the original sanding and refinishing process listed above.
