Moisture & your hardwood floors

Crowns are for your head, not your floors.

Recently I refinished a hardwood floor that previously had moisture issues that were not corrected properly, and it got me thinking about this subject.

The floor in question was crowned, where the center of every board bulges up.

When the house was first built there was a moisture issue of some kind.  The floor then cupped, because the boards would swell from the intake of moisture, and then edges push against each other.  So the builder fixed the moisture issue and got the floor refinished, soon after.

Where I believe the issue happened was that the floor was refinished too soon.  The floor didn’t have time to stabilize the moisture content and lay back down.  So when they sanded it, it looked flat, but when the moisture stabilized later, the process of sanding had taken too much wood off the edges, so now the centers of the hardwood floor had more material and was crowned.

If they had left it longer and let the wood stabilize more, then refinished it, it would have been a flat floor.

This is not the only way your hardwood floor can get crowned.  If there is a difference in moisture within the board, this can happen as well.

Since this moisture issue was well in the past and the it had been stable for a long time, with our refinishing we were able to get the floor nice and flat.

This was not the only reason the homeowner decided to get their floors refinished, as it was worn and due for an update.  We were  able to get a nice bright custom stain colour that opened up the space and that homeowners were very happy with.

The proper steps must be followed so the issues can be corrected once and for all.  This starts even before install, with proper moisture readings of the space and of the wood.  Allowing the floor to acclimate to the new environment is key.  Proper moisture control during and after install is very important as well.

So this was a good reminder that care needs to be taken with all aspects of a hardwood floor install and refinish.  From proper acclimatization,  and knowing the full history of the floor.

Floors as unique as you are!

At Evergreen we finish a variety of floors and work with customers who have a variety of tastes and preference. We wanted to take some time and let you know about our favorite high quality products and how we can make your floors look as unique as you like.

 Loba – On Top!

Loba is the only German medium sized company producing only hardwood finish. Thus the quality is just there.

When the project calls for a finish on top of the floor we use their waterborne finish and sealer. Loba produces a superior product designed for commercial grade wear and tear yet affordable for households alike.  They are also low VOC or solvent, so they are non-toxic for you and your family.  They also dry fast so you can get moved back in sooner!

I love to use these products because they consistently look great and hold up well.  You will love them for the same reasons.


Loba also makes a line of penetrating oils.  These are oils meant to be worked into the wood so the protection is IN the wood flooring, as opposed to on top with a water based finish.   This leaves your floor looking and feeling very natural and real.


The depth of colour and grain from the floor is unique from any other floor finish.  It enhances the natural look and feel of any hardwood floor.  There are many options as well for the colour you may want.


You can also create a layering effect with these penetrating oils, where you can have a base coat of one colour then a topcoat of a contrasting colour.

Also you can combine with a different water based stains and dyes. This is something unique to penetrating oils.   With Loba, depending on the exact finish system then you can top coat them with their water based finishes, if wanted.

I love the customization available, and you can find something truly unique for your home.

As you can tell there are many options for your home.
