Streaky Waterlox® ORIGINAL Satin Finish troubleshooting

Waterlox® ORIGINAL Satin Finish when applied as the last coat(s), will provide a satin sheen appearance (20-25 ° gloss level).

The recommended spread rate is 500 square feet per gallon per coat. This is especially important when applying the ORIGINAL Satin Finish as this will provide enough wet film thickness needed for the pigment in the finish to re-align itself before it dries. The proper spread rate will also allow enough time for the product to properly flow and level.

The Waterlox® ORIGINAL Satin Finish can streak and show start and stop marks:

  • if the finish has not been stirred before and occasionally during use, or 
  • if the finish is applied too thinly, or
  • if too much pressure is used to apply the finish, or
  • if the surface, product or ambient temperature is too hot (in strong, direct sunlight), or
  • if the finish is ‘over worked’.

Remedy for a larger project such as a floor. We recommend buffing the entire surface with a worn maroon pad, tacking the floor with a lint-free cloth dampened with regular mineral spirits (paint thinner)1;and re-coating the surface properly.

Take care in applying the finish with a smooth and even applicator stroke/pass. Try to feather in your start and stops and use smooth and even strokes to float the applicator with the finish over the surface, versus pushing down hard on the applicator.

Another choice would be to leave the project alone as the imperfections may fade after the finish has had time to cure.

Remedy for a smaller project such as a table or counter top. We recommend sanding the entire surface down with 220 – 320 grit sandpaper or 0000 steel wool; tacking the surface with a lint-free cloth dampened with regular mineral spirits (paint thinner)1;and re-coating the surface properly.

Sometimes Waterlox® ORIGINAL Satin Finish does not brush well on large surfaces and can be more temperamental because the brush bristles press further through the liquid and can dry in the form of lines/streaks. For large table tops or counter tops, we recommend either spraying the finish with an HVLP sprayer or applying an additional coat of Waterlox® ORIGINAL Sealer & Semi-Gloss Finish and reducing the gloss mechanically (e.g.: French polish, rotten stone, pumice stone, steel/brass wool, etc.). Reduction of the gloss through ‘mechanical’ methods is an art form, and is not something that everyone can do and do well. These methods are best used by those who are comfortable with them.
