Section I - Interior Wood Finishing

All interior wood to be finished must be free of dirt, marks, fingerprints and other surface contaminants. Do Not assume that new wood is free of contamination. All interior new wood must be cleaned before coating.  It only has to be done once, do it right!

A. Preparation and cleaning of new, interior wood as follows:

1. Sand with open coat, non-stearated sand paper 150 grit combined with a random orbital sander or use a medium/fine sanding sponge.
   CAUTION: Do not use steel wool. Particles that might remain on the surface can rust.
2. Sand with the grain.
3. Remove dust by duster brush and/or compressed air. Do not use tack clothes.
4. Remove all hardware prior to staining or finishing.
5. Protect areas not receiving a finish with masking or drop clothes.
6. Temperature should not be below 50 degrees F.

B. Preconditioning with water based conditioner.

Note: Preconditioning helps wood to absorb stain more evenly. It is highly recommended on highly visible pieces such as furniture, doors, cabinets, etc.. It is also recommended for specific types of wood such as pine, oak, cherry, poplar, or other woods prone to grain raise.

1. Make certain any wood to be conditioned is clean and free of defects.
2. Apply pre-conditioner by brush or airless spray.
   Spraying: Tip Size 3:09 reversible Pressure 2,000 psi
   Brushing: Apply liberally, wipe afterward with a clean white rag
3. Apply evenly to all areas of the wood being conditioned. If spraying slightly overlap as you spray. If brushing work one section at a time.
4. Coverage approximately 400 - 500 sq. ft. per gallon.
5. Allow 30 minutes to dry.
6. Sand all conditioned surfaces with open coat, non-stearated 220 grit sandpaper combined with a random orbital sander or a medium/fine sanding sponge.
7. Remove dust by duster brush and/or compressed air. Do not use tack clothes.
8. Wear a dust mask while working to protect your health.

C. Staining with non-grain raising dye stains

Note: Open time (dry time) can be slowed by adding “Extend” if necessary (See instructions and quantity recommendations on the label). More open time may be required for darker stains or larger projects. Preconditioning also helps to improve the workability of the stain.

1. Check to make sure stain color selection is correct. Apply stain by brush or airless spray. Spray in a well ventilated area or spray booth.
2. Apply liberally. Soak all areas.
   Spraying: Tip Size 3:09 reversible Pressure 2,000 psi
   Brushing: Apply liberally. Keep a wet edge.
3. Wipe afterward with Bounty paper towels or a clean white rag. Wipe with the grain. Do not allow stain to dry during wiping. If stain dries during wiping re-wet with water or remove with lacquer thinner and restain.
4. Dispose of all wiping paper towels or rags as normal trash. Materials soaked in the water based stains will NOT spontaneously combust.
   CAUTION: Although oil base stains are not recommended as part of our finishing system they can be used. Allow all oil base stain to dry 24 - 48 hours before sealing.

D. Sealing with water borne Sanding Sealer.

Note: Unlike oil based or lacquer based systems sealing can be done immediately after stain is wiped when using the Wood Iron water based materials.

1. Check to be sure all staining has been done correctly.
2. Apply Sanding Sealer by brush or airless spray. If brushing add “Extend” as recommended.
   Spray recommendations: Tip Size 3:09 reversible Pressure 2,500 psi
3. Spray as you would apply any lacquer based sand sealer. Overlap each pass by 50% with the succeeding pass.
4. If orange peeling texture is evident move the spray gun closer to the surface. If bubbles are evident turn the pressure up and move slightly faster. If there are missed areas wait until sealer is completely dry and then reapply to the entire piece.
5. Check with a glancing light to make sure all areas are sealed evenly.
6. Wait until sealer is completely dry or up to 1 hour.
7. Sand with 220 grit open coat sand paper combined with a random orbital sander and/or a medium to fine sanding sponge.
8. If the surface is sanded “through” exposing unstained wood reapply the Wood Iron water borne dye stain. The dye will “burn” into the sealer after sanding. Wipe off excess. Reapply and re-wipe if necessary.
9. After all sanding is complete dust with a duster and/or compressed air.
10. Wear a dust mask to protect your health.
    Safety Precaution
    Wood Iron Sanding Sealer is non-flammable. However, when spraying wear a respirator and spray in a well ventilated area.

E. Applying Water Borne Crystal Urethane (Satin, Semi-gloss, Gloss)

Note: Check to be sure that all surfaces are ready for a finish. Surfaces should be free of dust. Stain should be even and complete. Surface should be smooth with no rough areas.

1. Apply Top Coat by brush or airless spray. If brushing add “Extend” as recommended.
   Spray recommendations: Tip Size 3:09 reversible Pressure 2,500 psi
2. Spray as you would apply any lacquer based top coat. Overlap each pass by 50% with the succeeding pass.
3. If orange peeling texture is evident move the spray gun closer to the surface. If bubbles are evident turn the pressure up and move slightly faster. If there are missed areas wait until sealer is completely dry and then reapply to the entire piece.
4. Check with a glancing light to make sure all areas are sealed evenly.
5. Allow to dry completely or for 1 hour before moving.
6. Items finished are packageable within 6 hours and stackable within 48 hours.
   Note: Top Coat is a high solids finishing material. On trim one coat of pre-conditioner, Sanding Sealer and one coat of Top Coat is all that is recommended. On furniture, doors, cabinets, or other high wear surfaces two coats of Top Coat should be applied.
7. If a second coat is required apply within 1 to 24 hours of first coat application without sanding. If second application is done after 24 hours of first coat lightly burnish the surface with 220 grit open coat sand paper prior to application.
   Safety Precaution
   The Top Coat is non-flammable. However, when spraying wear a respirator and spray in a well ventilated area.
