Sealing of exotic wood with Synteko NATURAL

To enhance the colouring of exotic woods and reduce the discolouring of waterborne finishes, it is recommended to use Synteko NATURAL floor oil. It can also be used for sealing chemically treated wood e.g. ammonia treated wood. This final coating with waterborne finishes gives the floor special protection and relives maintenance.
In combination with Synteko TINTING PASTE it gives you the opportunity to colour your finished floor. The floor can be finished with Synteko PRO, TOP, TOP 5, NovaBEST and STAR after 16 hours in normal conditions.
TOOLS:
  1. Applicator with rubber bla de (squeegee) 300-500mm
  2. Small brush or a small applicator at the edges
  3. Buffing machine with 2 adjustments (150 and 300 r.p.m.)
  4. Red pad for rubbing
  5. Red pad and a non-flocculent cotton cloth (5-6 pc/approx. 20 m²) for polishing

1. PREPARATION

Machine sand the surface to remove old treatments and impurities in the wood. The first sanding is made with a coarse sandpaper and high roller pressure. Make the floor surface as even as possible. If the floor is uneven in spots, sand locally to even out these areas. The final sanding is made with 100-120 grit sandpaper or screen, and with the lowest possible roller pressure. If roller pressure is too high, the soft springwood may be compressed. When moisture from the finish affects such softwood, it will raise the grain of the floor by swelling back to its original volume. Vacuum and tack the floor before applying the finish. Do not forget to remove dust on skirtings, windowsills, radiators, etc.

2. TINTING
The mixing of NATURAL oil with TINTING PASTE is easily done by adding the tinting paste to the oil and shaking the container thoroughly (see separate Product Information). Always use full tubes of tinting paste. Be sure to completely empty the tube into the oil in order to avoid colour differences. Tinted oil has all same properties as neutral oil.  

3. PREPARATION FOR OILING
Before starting work, protect adjacent areas against splashing and spilling. The number of coats necessary depends on how much oil the floor will absorb. The best result is obtained with several thinner coats. Softwoods and beech absorb more; hard and exotic (oily) woods absorb less oil. The wood should be well fed, but not overfed. Plan your work well, large areas should be divided into smaller areas of 15 - 20 m² (161 – 215 ft²) or areas which are possible to handle in 20 minutes. In hot, dry weather the areas should be further reduced. Shake the can carefully before and during the use.

4. APPLICATION
Apply Synteko NATURAL with an applicator with rubber blade (squeegee) or pour directly on floor and distribute with red pad. Use a small brush or a small applicator in areas where it is difficult to reach with the normal applicator. Too much oil in puddles will splash around. Use 150 r.p.m. or similar adjustment of the buffer. Redistribute the oil with a red pad - it is necessary to start within 20 minutes in normal temperatures. Add more oil if necessary. Repeat the process as long as the wood is absorbing the oil. When the wood is saturated, rub the whole surface with a red pad using a 150 r.p.m. buffer. Remove all excess oil with a non-flocculent cotton cloth and a red pad. Change cloth or pad when it is filled up.  

5. POLISHING

After 3-4 hours the floor must be buffed using a red pad. Final polishing is done with a dry non-flocculent cotton cloth wrapped around the pad and 150-300 r.p.m. adjustment of the buffer. Do not allow unabsorbed oil to dry! Dried unabsorbed oil gives glossy spots on the surface.

6. RE-COATING WITH WATERBASED FINISHES

Before finishing the surface must be light buffed with a dry non-flocculent cotton cloth wrapped around the pad and 150-300 r.p.m. adjustment of the buffer to take care of any bleeding oil.
NB! Put all organic materials like cloth in a metal container filled with water for at least 16 hours to avoid self-ignition. Dispose of them according to local regulations.
