I need help choosing finish for flooring. I am considering (longleaf heart pine) to be installed.

I would have preferred an engineered pre-finished pine but find the choices very limited and expensive. If I go with solid pine unfinished, it is more cost effective but I am concerned about the quality and safety of the finish.

I prefer a matte look to the finish. Concern for wear and trying to avoid daily vacuuming, I am looking for a natural look with durability. I don't think I can get that with an oil seal finish.
​
What do you suggest? I saw on your site a pine floor stated to be finished with the bio poly and topped with nano tech. With the nano tech on top?
Does that make it shinier?

Does your finish end up as hard as a prefinished floor? Is it safer?

I am so tired of doing research and want to get on with getting the job done but I don't want to make the wrong choice.

FYI, This would be for my 2nd floor, about 750-850 sq ft at this time. There is much less wear and tear on the 2nd fl. If everything goes well there, I would consider it for the first floor .

HOPE TO HEAR FROM YOU SOON.

Bio Poly and NanoTech

---

Hi Bianca, 

Pine is a softer wood but it works out pretty good on floors. 

In short, if it's upstairs, I would probably start with the Bio Poly Natural and see if you feel you need the NanoTech top coat. 

Yes. Bio Poly Natural is on many pine floors. We use a pine resin from nearby in Georgia in that product. There is also beeswax and special linseed oil.
I love it. I think it's the most beautiful, natural finish there is. I use it without hesitation in bedrooms and low traffic areas or on any floor that calls for an oiled or rustic look. 
It's plenty strong for floors. It's used on exterior decks and timbers as well. If there are to be overnight spills it's better to use NanoTech since that will fill in cracks and crevices, whereas the Bio Poly is a penetrating finish. It protects by saturating the wood fiber cell yet remains breathable. This is the flattest sheen of any floor finish we offer. 

The main issue with the pine floor is denting but I wouldn't let that be a deal breaker. It's more sustainable than engineered wood and there are benefits long term to a solid wood floor. 
​
If someone walks on pine floors with heels it can leave marks regardless of the finish. The  trick is to use a finish that accommodates that. 
If the finish is too hard it will be too brittle for pine. There must be a balance of flexibility and hardness. Bio Poly and NanoTech both are great at this. Mountain is too but that is a high gloss cashew resin and I know you want less sheen. 

For medium to high traffic floors we use NanoTech. This is used in commercial and industrial settings as well as residential. It has an excellent safety profile and it is one of the few professional grade floor finishes that I can use with having a reaction. I've seen it wear very well on old pine floors in high traffic businesses here in Asheville. It is rare that someone needs anything stronger than NanoTech on residential floors. In the cases they do a stronger finish we use the Easy Safe 1k. This has as good or better performance of the more toxic 2K urethane's but it requires no mixing and is much safer. I can't smell it at all. It's incredibly tough and scuff resistant without being brittle. 

Instructions are at the bottom of the Bio Poly Natural page. Nanotech's instructions are on the back label. It is very simple (just mop on). There are floor finish mops on the website that work well. 

Hope this helps.
Best wishes,

Tom
