I need instruction steps for application of Bio Poly Natural on a large wood home.
What's the best way to apply the finish to hardwood trim?
How many coats?
Sand between coats?
Finish coat a different product?
Where can I buy BioPoly in quantity in southern Maine?
Bio Poly Natural is the best interior wood finish overall for homes with a lot of wood. It's easy to get a beautiful finish with deep wood grain illumination. The special oils combined with our local pine resin and beeswax creates a really warm and rich look to the wood that just feels good!
Application: Interior hardwood trim usually only calls for a couple coats of Bio Poly Natural. Most of the time, if it needs a 3rd pass, we are really just polishing the wood. Instructions are on the can but in short, we wipe, brush, mop, spray or roll the product on and then wipe down with a dry brush, mop or rag (not always necessary).
Sills: Window sills do well but for wood in harsh sun and condensation we apply NanoTech over the Bio Poly, sometimes on the sill itself and other times the whole window trim. This works well over Bio Poly and can be done later if needed. It creates a waterproof film for situations where water will pool up and slowly evaporate in the sun, day in and day out. It's also easy to apply a bolstering coat to these sills years later if needed.
Severe Conditions: Some custom homes are high altitude sun / snow exposure, like lodges and such, we will use Easy Safe on the sills as the final coat over NanoTech in those instances but that's usually only called for in commercial settings.
All the rest of interior trim (doors, molding, baseboards, shelves) does well with just Bio Poly Natural.
Sanding: Sanding on trim in a hardwood house can go a couple ways:
1. The Basic Builder Grade prep - which is very little sanding, maybe 120 grit if any at all. No sanding is needed for the product to work. Sanding is done for aesthetics, smooth feel and sometimes for a polished wood sheen.
Often all the wood is coated in the garage or basement, stacked and hung. Trim carpenters sometimes hang the trim right after it's been coated since the wood can be given a first coat and handled right away without harming it. Sawdust and all of that is a non issue as well. We just go around and wipe down the final coat after the walls are painted, before the carpet (in most cases).
2. Custom Painter Grade prep- which involves sanding as the wood calls for. That's
a decision based on wood type and what the customer wants; usually 100 grit
on orbital sanders before coating to remove mill glaze and saw lines. Then 150-220 between coats. Some painters will have a piece of wet dry 320 on hand to wet sand some areas often touched by hands as they go ( optional extra step).
Flat Finish for Log Home Interiors and Timber Frames: Often Bio Poly is used on large Timber Frame and Log homes that don't need any sanding. One coat is applied and that is all the beams and logs need most of the time. This gives the wood rich nourishment in coat and has real nice flat finish that is washable and helps prevent dirt / sun / water from damaging the wood.
In these cases, the wood is generally thirsty enough to absorb nearly all of the finish and there is very little if any wipe down necessary. On beams & logs, one guy usually goes first with a whizzy roller to apply the finish and then another goes goes behind him to back brush into the wood with a fairly dry brush. Someone goes around to check for drips, flashing or runs at the end of the day. We use a brush on a pole or maybe a small T-Bar for that and it doesn't take very long at all. If the wood is green or less thirsty, then we will add a quart of Pure Citrus or Corn Solvent per gallon to insure it soaks in without a wipe down.
Each project has it's own nuances. Hopefully, the above covers the basics. Sample pints are very helpful for nailing down the exact approach and look beforehand.
There is detailed information on the bottom of the Bio Poly page which also has buy now buttons at the top of the page. We offer Earthpaint products directly from the factory at our web-store which is where that link will take you.
