Waterlox URETHANE Finish Application Guide

Waterlox URETHANE finishes are the ultimate in clear polyurethane finishes for indoor use. Our URETHANE finishes are processed with the highest urethane content available on the market today. They are also soybean oil-based, giving them the ability to form a tough and hard finish without the typical yellowing or ambering characteristics of most other urethane products containing linseed oil. The URETHANE Gloss is so clear you can read the date off of a dime on the bottom of the can. All Waterlox URETHANEs are recommended for floors and other interior surfaces and will yield a clear, pale color.

  • NIOSH/MSHA-approved respirator during application (for organic vapor).
  • NIOSH-approved dust mask for sanding (if sanding to bare wood).
  • Read and carefully follow label instructions, guidelines, warnings and cautions.

General

Product Options

Waterlox Sealer Product Options

One of the WATERLOX Sealers as listed below is OPTIONAL to seal the wood prior to the application of Waterlox URETHANE finish as the first coat of the system. If using one of the Tung Oil sealers, this will lead to a slightly more golden/amber final project finish due to the tung oil as compared to using URETHANE along for all coats.

  • ORIGINAL Sealer/Finish – TB 5284
    Optional first coat of the system. This Tung oil-based sealer seals the wood from within and provides a warm and golden/amber color to the wood. It also beautifies, richens and shows off the depth of the wood. One to two coats (depending upon the hardness of the wood) are required for adequate film build.

  • TRUETONE® Color-Infused Tung Oil – TB 70XX
    Optional first coat of the system. This innovative high-solids, VOC compliant, Color-Infused and Tung oil-based sealer and stain seals the wood which minimizes grain raise. It also beautifies, richens and shows off the depth of the wood. Must be driven into the wood and excess removed.

  • UNIVERSAL Tung Oil Sealer (UTOS) – TB 1000
    Optional first coat of the system. This innovative high-solids, VOC compliant, Tung oil-based universal sealer seals the wood which minimizes grain raise. It also beautifies, richens and shows off the depth of the wood. Must be driven into the wood and excess removed. One coat is required for adequate film build.

Tools

Not recommended for use with a roller.

For Large Projects:

  • An 8-12" synthetic applicator and a paint pan large enough for chosen applicator.
  • A quality natural bristle brush or paint pad recommended for use with oil-based finishes for cutting in edges.
  • Abrasive pads for sanding and smoothing between coats are REQUIRED for adhesion.
    • Maroon pads, surface preparation pads (SPP pads) or a 100-grit screen are recommended.
    • Also 320-grit sandpaper, 0000 steel wool or other equivalent abrasive.

For Small Projects:

  • A quality natural bristle brush, lambswool hand pad or paint pad recommended for use with oil-based finishes.
  • Abrasive pads for sanding and smoothing between coats is REQUIRED for adhesion.
    • 320-grit sandpaper, 0000 steel wool or other equivalent abrasive.
Surface Preparation

Testing

Waterlox URETHANE will alter the appearance of the wood. Proper testing of the entire process should be completed before beginning.

Preparation

  • Vacuum the surface thoroughly with and across the grain to remove as much sanding dust as possible, including all surfaces that could hold dust.
  • Lightly dampen a rag with mineral spirits or paint thinner and wipe the wood surface to pick up any remaining sanding dust. Allow the mineral spirits to evaporate (15-30 minutes) before applying.1
  • Tape off or cover any surfaces not being coated.
Application and Product Handling

Product Handling

  • Waterlox URETHANE Gloss – NO shaking or stirring required or advised.
  • Waterlox URETHANE Semi-Gloss and Satin Sheen - Shake or stir contents before use. Stir contents occasionally during use.
    • BATCHING. If more than one container of finish is needed to complete a coat, the containers should be batched together before starting the coat.

Application Steps

  1. OPTIONAL Sealer: Apply Waterlox ORIGINAL Sealer/Finish, TRUETONE® Color-Infused Tung Oil or UTOS following proper application and drying directions. Then, apply two (2) coats of Waterlox URETHANE Finish at the chosen gloss level with 6-12 hours between coats.
  2. Pour out the amount of product needed for the first coat.
    • If working from a previously opened container, straining through a medium to fine mesh paint strainer may be required.
  3. Apply first coat of Waterlox URETHANE Finish with the grain and at the recommended spread rate.
  4. Allow to dry for 6-12 hours.
  5. Sanding between coats is required for adhesion. Abrasive pads for sanding and smoothing between coats is REQUIRED for adhesion. Maroon pads (e.g.: surface preparation pad, a.k.a. SPP pads) or a 100-grit screen. Also 320-grit sandpaper, 000 steel wool or other equivalent abrasive.
  6. Lightly dampen a mop, lint-free rag or micro-fiber mop with water or regular mineral spirits1 (paint thinner) to remove dust. Allow to evaporate 30-45 minutes (until dry appearance) before applying Waterlox URETHANE Finish.
  7. Apply the second coat of Waterlox URETHANE Finish.

Application Procedure

Large Projects:

  1. Clean the new, unused applicator with painter’s tape, lint roller, in the dryer or with a vacuum before starting.
  2. Pour out the Waterlox URETHANE Finish product into a paint tray.
  3. Dip the applicator fully into the paint tray to saturate it.
  4. Following the grain, pull the applicator (spread the finish) toward the opposite wall evenly. Hold the applicator with light pressure and at a slight angle to maintain a wet edge.
    • To avoid lap marks, maintain a wet edge by overlapping sections previously finished by several inches. Be sure to feather the finish at every start and stop.
  5. When cutting in edges do not work more than 5-10 feet from the field-applied finish.

Small Projects:

  1. Clean the new, unused lambswool applicator or pad with painter’s tape, lint roller, in the dryer or with a vacuum before starting.
  2. Pour out the amount of finish needed for the job or dip applicator into the can and spread evenly.
  3. Following the grain, lightly drag the applicator or brush from one end of the project to the other to remove applicator marks. Hold the applicator or brush with light pressure and maintain a wet edge.
  4. Wipe off any drips with a clean rag if necessary.

Clean Up and Disposal

Clean application tools immediately with regular mineral spirits1 or paint thinner. Do not pour extra product down the drain! Allow rags that are wet with product to dry in a well-ventilated area before disposal. Properly dispose of rags, applicators and waste. DANGER! Rags, steel wool or waste soaked with Waterlox may spontaneously catch fire if improperly discarded. Immediately after use, place rags, steel wool or waste in a sealed water-filled metal container.

Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. Keep away from heat and flame. Prevent build-up of vapors by opening all windows and doors to achieve cross-ventilation. Use only with adequate ventilation. Do not breathe vapors or spray mist. Ensure fresh air entry during application and drying. If you experience eye watering, headache or dizziness or if air monitoring demonstrates vapor/mist levels are above applicable limits, wear an appropriate, properly fitted respirator (NIOSH/MSHA approved) during and after application. Follow respirator manufacturer’s directions for respirator use. Close container after each use. Avoid contact with eyes, skin and clothing. Wash thoroughly after handling. FIRST AID: In case of eye contact, flush immediately with plenty of water for at least 15 minutes and get medical attention; for skin, wash thoroughly with soap and water. If you experience difficulty in breathing, leave the area to obtain fresh air. If continued difficulty is experienced, get medical assistance immediately. If swallowed, do not induce vomiting. Call physician immediately. If spilled, contain spilled material and remove with inert absorbent.
