I understand the sense of caution. Callbacks are not good and can eat away at your profits. To answer your question: I have used products supplied by flooring distributors, and have included products from Ardex, Mapei and Fritztile. They were all used with an appropriate primer to facilitate bonding to what they were placed over. Additives were included to make the product less-likely to break apart and powder. I especially like Ardex SDP (Self Drying Patch)...because the PSI (pounds per square inch) rating is lower than some other products. Self leveling formulations can achieve a very high PSI and can be very difficult to nail into, even with pneumatically assisted fastening tools. When I used a product with a high PSI, I sometimes would have to drill pilot holes and manually drive in hardened spiral flooring nails. I never had a floor patch crumble. I figured...if I used a good patch, and if the substrate was well-fastened and didn't move much, I believed the installation would be OK. I believe that you have to have significant movement to get a decent patch to fall apart under a finish product. I came to wood flooring out of a family business that specialized in resilient flooring materials, so I learned a lot about what you can and cannot do regarding floor patches and their application. I will say in closing here (for general consumption) , especially for the DIYer,... if you try to use calcium carbonate patches (usually white in color...and I won't mention brands) ...you will experience quick breakdown of the product, because they are fragile and will crumble easily. If it looks like plaster of paris, it is not a suitable floor filler or patch...my opinion.

I'm a fan of Hickory. Love it! I love it's STRONG variation! Yep. Variation is the word that can be used for Hickory. If you are going for "mid-tone" then it means the Hickory is stained. No problem. That's fine. Hickory takes a stain very nicely. But it will still have plenty of variation. The stain will even that out a little bit, but not entirely. The finish is UV cured urethane. I'm not very excited about that finish. If you are going for factory finish, you will want to work with the TOUGHEST finishes on the market (that's why you go with factory finished...for the TOUGH finish). The UV cured urethane is a ho-hum type of finish. Average would be the best way to describe it. The thickness of the plank is 3/4" = normal for sold. The plank width is 5" with random lengths UPTO 60" (5ft). That tells me there will be many planks in the 3' - 4' range. Again, this is ho-hum average. And with a wide plank product, it will need "glue assist". And Hickory certainly needs it because it has a bit more movement (less stable) than white oak. And then there is the "low gloss" format. The low-gloss finish on this depth of colour = nightmare to live with. It will show dust, etc as well as oily foot prints, sock prints, paw prints and will look hazy at certain times during the day. The "haze" is part of the chemical make up of the finish itself = that's how they take away the gloss...they haze it with a chemical additive. The haze goes away when you sand and refinish the floor. That's the only way to fix it. If you must have a mid-tone floor, I would recommend a TOUGHER finish (aluminum oxide or ceramic infused polyurethane) in a satin. Satin is FAR MORE livable. It offers a lovely glow without being shiny. It hides skin oils (like paw prints from dogs) because it is the same gloss level as skin oils....it isn't hazy....you get the idea.

I too cannot see the savings of remove+replace. A sand/refinish averages $5/sf. It is minimally disruptive (ie. it does NOT involve demolition) and it will cure in 10 days (assuming you are using a high-end water based finish). Now an engineered hardwood is SUPPOSED to be more expensive than solid. Yah. I said it. Engineered (same cut, width, thickness, installation method) should be more expensive than solid. Hmmmmmm. My spidy senses are tingling. Now on to the cost of hardwood upstairs. Carpet removal/disposal = $1.50 - $2/sf (depends on where you live). Repair and prepare the wooden subfloors (usually 'bad' underneath carpet...carpet hides the WORST subfloors) $2-$4/sf. Yep. Just ASSUME you will be spending $3/sf for the subfloor prep upstairs. Now for the cost of solid hardwood (regular 3" width) = $5/sf. Installation + finishing = $3-$4/sf. Right. A regular solid hardwood (nothing special) with install = $8 - $10/sf. Now compare that to a 'sand and refinish' of $5/sf. Wow. It is CHEAPER to do the sand and refinish. Hmmmm. Now imagine the COST of demolition for the HARDWOOD....yep. You can add MORE to that cost. And again the subfloors have to be looked at. More costs. Now imagine the cost of a MORE EXPENSIVE engineered hardwood....$8 - $12/sf for material only. Installation is extra ($3-$4/sf for factory finished hardwood). I tell ya. The $5/sf sand/refinish is looking REALLY GOOD right now. Ignore the width of the planks. They are classic and are probably appropriate for the age of the home. It is your money and your home. If you believe an engineered hardwood is CHEAPER than $5/sf sand and refinish (including install and subfloor preparation) then you are welcome to find out the reality of the situation. We are going to tell you the 'cheap' wide plank engineered hardwood is not going to give you the 'life expectancy' that a 'regular' 3" wide solid hardwood ($5/sf material). It just won't.

We have red oak floors covered with carpet in our living room in our 50 year old ranch. That room opens up to our dining/kitchen area which is sheet vinyl on a subfloor (placed over old vinyl.) We were wanting to do glued down engineered hardwood over the entire area and the hallway. The guy who measured said we could put a subfloor over the hardwood to bring it up to the level of the vinyl. Sounded easy. Now the installer says we need to remove all the old hardwood and vinyl and do new subfloor over all of it. Who is right? Is a floating installation an easier/better option?
