WOCA Guidance

 Application Guide

  WOCA Master Floor Oil and Diamond Oil may be used on all unfinished, freshly sanded and newly laid wood floors in all wood species. To be used on untreated and lye primed woodwork such as interior floors, stairs, panels and furniture. The Master Floor Oil has excellent penetration properties and therefore ensures a hardwearing, dirt and water resistant surface. Depending on the desired effect and species of wood, WOCA can enhance, mask, or modify natural properties of the wood. Product, room and floor temperature should be between 60°F–85°F. Ensure good ventilation at all times during the application and drying time.

Optional Pretreatment: 

Lyes, Active Stains and Pre-colors

Before application of each pretreatment, ensure that all safety precautions have taken place and necessary equipment is available. After your floors have been freshly sanded is the time to apply WOCA's various lyes, active stains, and pre-colors. These products need to react with bare wood and the chemical properties within them. Most of these treatments need 24 hours to dry before the initial application of master oil - be sure to include this in your timing. Most pretreatments need to be applied evenly, without any liquid pooling on the surface, using a painter's brush or sponge.

Step One:

Cleaning and Preparation of Surface

The hardwood flooring or woodwork should be freshly sanded to the 100-120 grit range. After most pretreatments, a buffer with a maroon pad must be run across the entire surface to "denib" the surface of any raised grain and imperfections.

Clean with a mixture of 125 ml Wood Cleaner mixed with 5 liters water. The surface must be completely clean, dry, and free from grease before the application of the master oil or a colored oil. Maximum humidity of the wood should be 12%, oil- and room temperature at least 65°F. Ensure good ventilation at all times during the application and drying time.

Step Two:

Application and Saturation of Master Oil

Shake the WOCA oil container well before and during application, especially with colored products that contain pigments that will rest on the bottom. Apply the oil in an even coat onto an area of approx. 150 square feet with a paint roller. Let the floor absorb the oil for approx. 20 min. Subsequently, the oil is worked into the wood with a white, thick polishing pad either manually or for large areas with a buffer. Polish for approx. 15 min. until the floor appears saturated with oil. Please Note: Any excess oil appearing on the surface should be removed with cloths or paper or moved onto next section of floor to be oiled. Continue buffing the floor with white polishing pads until floor is fully saturated. Excess oil can be wiped up with lint-free cotton towels ( or old clothing items, t-shirts, sweaters, etc.)

The initial buffing is the time to add WOCA patina discs to the bottom of the white pad, for an ultra-fine sanding and silky smooth texture.

WARNING: WOCA is self-combustible due to the solvents in the oil mixture. Be sure to appropriately dispose of oiled rags by either completely soaking them in water and placing in a bag including water, or lying the rags completely flat on a concrete surface! This cannot be stressed enough.

Step Three:

 Subsequent Coats of Oil

The initial application of oil is hardened after approx. 6 hours at room temperature of 68°F and completely hardened after 5 days. A second coat is recommended on all woods, and a third coat is recommended for softer woods such as Pine, Walnut, and American Cherry. Keep in mind, the boards need to be completely saturated with WOCA oil, if the luster of individual boards is noticeably uneven, another coat may be needed.

Step Four:

Additional Surface Treatment

An additional top coat of WOCA maintenance paste can be added for an additional protection layer, and to increase the sheen of the surface. WOCA maintenance paste should be applied using a white polishing pad, and should be applied even across the surface. Edges and hard-to-reach spots will need to be applied by hand.

If a slightly more matte appearance is desired, use WOCA polishing cloths underneath the white pad to slightly decrease the sheen of the wood.

Again, all rags and material saturated with WOCA should be properly disposed of. Due to the solvents in the oil, these can spontaneously combust and cause serious injury.

Below are recommendations for caring and maintaining your WOCA oiled floor. Unlike conventional floor finish types, your can be easily brought back to life with a little maintenance and reapplication of oil, much like a pair of leather shoes. When properly cared for, a WOCA oil finished floor will last virtually forever and will never have to be sanded. A wood floor finished with WOCA oil is resistant even to excessive wear and most liquid spills. Proper maintenance is simple.

Preventative Maintenance

  • Regularly vacuum or dust mop your floor to prevent sand or abrasive dust buildup that can scratch the floor finish.
  • Place high-quality doormats at each door to reduce sand and dirt coming in from outside. Also, if you have wood flooring in your kitchen, a throw rug with a soft or felt backing should be placed in front of the sink area to catch spills and splashes.
  • Use felt furniture protectors on piece that are constantly used and moved.
  • Wipe up spills and spots immediately with a damp cloth.
  • Keep pet nails trimmed and filed in order to minimize excessive wear.

 Regular Maintenance

  • Once to twice a month, moist mop your floors with WOCA Natural soap and use either a cotton-based mop or cotton swiffer-type mop. If time is limited, focus on entry areas and kitchen, which experience the most dirt and grime.
  • One to two times a year, moist mop your floor with WOCA Oil Refresher. This will introduce a small amount of oil into the floor to freshen it and extend the time before a re-oiling becomes necessary.
  • If cleaning more than four times per year becomes necessary, use WOCA Soap. Please remember to still moist mop with WOCA Oil Refresher twice a year.
  • For commercial floors that require frequent cleaning, use WOCA Master Soap. The Master Soap is formulated to allow virtually daily cleaning without leaving behind a residue. Apply WOCA Oil Refresher three to four times a year. 
  • Do not use ammonia or oil-based wax, polish, household dust treatment chemicals, abrasive cleaners, furniture cleaners or any other non-WOCA brand product to clean your floor. 
  • Do not wet mop the floor, as excess moisture may cause damage to your wood floor. 
  • Only WOCA products should be used to clean your floor, all of which are available through Midwest Flooring.

 Repairing Scratches

  • Light scratches are best repaired by hand rubbing WOCA Master Oil or Master Color Oil on the affected areas using a cloth. If necessary, first clean the area to be repaired with WOCA Wood Cleaner solution. Be sure area is dry before applying oil. Leave the oil to absorb for a short period of time before thoroughly buffing and then removing the oil from the surrounding area.
