Apples to apples floor finish
Wednesday, April 7th, 2010
I do a number of estimates for my floor business and I am always perplexed by the lack of information other floor companies are providing for the homeowner. Let me bring about a few real world points for people in order to dispel the myths surrounding the “bidding” process.
1) Two coats versus three coats versus coverage rate
Honestly this is a six versus one half dozen comparison. Your average floor finish has a recommended coverage rate for application. Some finishes have an optimal application range of 300 square feet per gallon where others are at 500. This has a big impact on the “mil thickness” (durability) of the finish. Three thin coats will actually be less durable than a quality two finish coat job. Cheap contractors stretch finish thin when applying it. Three coats sounds like a better thing, but is only a repeat visit and more work for the contractor if the coverage is less than adequate.
2) Resins and solids content
This is a real hidden point of discussion for some floor companies, particularly low priced companies and large outfits. Waterborne finishes have a protective resin suspended in water that is the “thing” that provides durability. The chemical composition of this resin has a tremendous impact on durability. Cheap floor finishes have weak resins and are “watery” with coverage rates near 600-700 square feet per gallon. They are lower in solids (the resins that provides durability).
3) Two component versus one component waterbased finish
One component floor finishes have minimal scuff and scratch resistance. They rely simply on oxygen to link the finish resins. Two component finishes rely upon a chemical crosslinker to “matricize” the finish resins and form a really tough scuff resistant floor. In talking with several finish chemists during NWFA schools, I have found that two component finishes fare almost twice as well in taber abrasion tests that test durability. For a perspective single component finishes can be about $25-50 per gallon, where a quality two component waterborne ranges from $80-110 per gallon.
CHEAP ONE COMPONENT FLOOR FINISH
DURABLE TWO COMPONENT FLOOR FINISH
My Point!!!!
Ask your contractor about these points. Why? Because if they don’t have an answer they are NOT a professional. They are a “guy with a sander” who can multiply a square foot price and use a tape measure. Please make a fair comparison when evaluating floor refinishing estimates. Otherwise you will be taken for a ride by a snake oil salesman and have a worn out floor in two years.

Real world waterbased finish
Sunday, April 4th, 2010
I get asked so often about finish durability. Honestly, my answer is always to explain the features of various finishes and suggest only the types of products I would use on my own home.
Two years ago in April 2010 I applied three finish coats of Glitsa HP two component waterbased finish to my floor (Matte sheen). Today while I was cleaning my floors using our suggested method and was really impressed with how they still look great. My children are two boys ages 4.5 and 2.5 (they’re wild and crazy) and they are my best testers along with my dog who is young and crazy. The photo below is pretty much the best proof I can give you for the real world performance of a finish. No hyped marketing behind this one, just real world for someone else to see if they are wondering about durability.
This isn’t that I am sold on only one particular finish, just that I have this product in my house on a daily basis and can personally vouch for how well it performs in durability.

White Lines Syndrome
Saturday, August 1st, 2009
The latest trend in wood flooring has definitely been for darker floors and wider boards. Exotic wood flooring has also seen growth in market share. One of the unspoken problems is that when seasonal movement occurs within the boards of the floor some finishes can actually become stretched out during this process and they leave a white line down the seam of the boards. This problem is particularly bad with waterbased finishes that have come to dominate the market with low VOC laws emerging in many states. Waterborne finishes lay across the floor and essentially act as a hardened sheet of plastic that resists traffic.
Using an acid curing conversion varnish or true “Swedish” finish is the best option to prevent this problem. This is because the acid curing finishes will truly break their bond at the edge of each board and stick to the edges of that board during seasonal movement.
If you are planning a flooring project that requires wider boards, dark stain, or both I recommend thoroughly discussing the project with your contractor to prevent this problem. In fact there is so little published information for this problem because the industry doesn’t want you to know that there is a dark side to new technology. When white lines occur across your wood floor they almost always require a full refinish to remove and that is never a fun option for your time. If you would like more information please contact us for a PDF of the problem.
