SEALING 

  

 

 APPLICATION WITH APPLICATOR OR ROLLER

Suitable product: Synteko SEALMASTER

If you prefer to work with an applicator or roller when applying the first coat, it is very important that the application is even. An uneven first coat will result in uneven colour tones, especially on oak.
Do not permit finish pools to remain on the floor. If the finish is poured directly from the container, it must be quickly spread before the wood absorbs too much moisture. If possible, apply the finish parallel to the shortest wall of the room (from one long wall to the other). Overlap times will thus be as brief as possible. Work gently with the tool so that no finish drops splash across the floor. Should this occur, the drops must be removed before the next coat is applied. One litre of finish should suffice for between 8m² and 20 m², depending on the absorbency of the wood type. 
The golden rule is to give the wood what it can absorb. You thus attain the best foundation for the next coat, and at the same time, the drying time is optimised. Be sure to apply enough finish to achieve even wetting of the wood. A wet finish darkens the wood, but afterwards as the finish dries, the wood lightens again. Wait until the wood has an even colour tone before performing intermediate sanding. If the finish coat is thicker in some places, it takes longer for the water in the finish to evaporate and the surface appears spotty because of colour differences. If the next coat is applied too early, it will take a long time before the floor achieves an even colour tone.

NB! To enhance the colouring of exotic woods and
reduce the discolouring of waterborne finishes especially on Russian ash, it is recommended that you use Synteko Exotic Wood Sealer (EWS).

 

 

  

APPLICATION WITH SPATULA

Suitable product: Synteko SEALER

Applying the initial coat with a spatula has become more common in working with waterborne floor finishes. There are several advantages over brushes or rollers: it is easier to apply finish evenly with a spatula; the drying time is much shorter; and grain raise is minimal. Intermediate sanding is often unnecessary and vacuuming between applications is thus avoided. This method works best if the finish has a thick consistency.

The spatula should have a stainless steel blade and be sufficiently pliable that it can follow the contours of the shallow depressions on the floor. Using a spatula, one litre covers between 20m² and 30 m², which means that the finish must be applied three times to attain the same thickness as achieved with a brush or roller application.
The first two applications are made wet-on-wet for optimal evenness. Thereafter, wait approximately 15 minutes until the surface has an even colour tone before the next application. It is important that the spatula be kept sharp so that it functions as a scraping iron and cut the grain raise. This is necessary for achieving good results without intermediate sanding.
