Delamination and Flaking of Nhance wood renewal

This topic is a bit old at this point but without seeing it, I am about 100% sure that you are dealing with a prepping issue and possibly a material issue as well.

Nhance is a "Get rich quick type of scheme". It's less expensive than hiring a professional refinisher and there is a reason for it. I am not an expert on the products, process, or company so from what I can find here is what it looks like they are doing. First they don't sand your cabinet surfaces which takes more time, labor, prep, etc. Second, it appears to be tints mixed into the clear coat. Let me go into detail a bit.

1.) They should have first degreased all surfaces with a strong degreaser. This can range from Acetone to TSP. Most likely they did this or at least we would hope.
2.) They should have physically sanded all surfaces after degreasing them. Let me make this very clear to all who may read this and hopefully it will save you or a friend thousands of dollars. Nhance does their refinishing faster than others because they apply a no-sand chemical to the surfaces. This is a harsh chemical that basically eats away at the surface to create a more three dimensional surface to gain mechanical adhesion between the paint coating and surface of cabinets. Let me make this clear to everyone out there, I have done a lot of research and asking around from professionals all across the the U.S. and they all sand with sand paper. I hate it myself and sanding is the worst part of any job but it is probably the single most important step you can take in the recoating process.

With no-sanding chemicals, there is no way to know where you stand with the chemical doing it's job. A chemical on a Lacquer will react very differently compared to a conversion varnish, polyurethane, pre-cat lacquer, latex, oil, and the list goes on and on. Do they know what clear coating is on your cabinets? When you sand with sand paper you accomplish two things;
A.) You know where you stand by looking at the scratch marks and sheen change. Usually shiny sheen changed to a flat dull finish when sanded. If you use a 180 grit or 220 grit you know where you stand.
B.) Equally important, a no-sand solution will not level your existing cabinet surface. Meaning it will not smooth out dings, previous dust in the surface paint, etc. So if you want a perfectly smooth factory finish, don't use a no-sand type product. These products have a place for a small DIY project but not your kitchen cabinets.

3.) I have looked into NHance to see what the product coating is that they use. I believe they say it's a proprietary coating. I can promise you that it's nothing special and in fact I would put my money on it being either a Conversion Varnish, Pre-catalyzed Lacquer, or Polyurethane. Most likely a polyurethane. All have different drying times and curing times. All are durable but not equally durable. Cabinet Manufacturers usually use conversion varnishes and Pre-cat Lacquers for the record. If you want to learn more about kitchen cabinet finishes take a look at www.KCMA.org which is the Kitchen Cabinet Manufacturing Association. To be a member, they have guidelines as to the correct process in cabinet finishing for professionals and manufacturers.

I would like to get the input from other professionals on the NHance topic. I shutter to think of the problems their process could cause down the road. For anyone thinking about refinishing their cabinets or wood work of any kind, ask the contractor to spell out the steps they will take in the painting, staining process.

They probably are correct about the 30 days to cure. Many paints are like that so they may have been honest with you. The real question is how the Nhance product is holding up at this point since the original posts was written in 2010. Would love to hear a follow up.

Hope this helps someone.
