Q:I live in California and have a new cedar-sided house. I was told that we are in a low VOC area. What PPG ProLuxe product do you recommend?

A:The following PPG ProLuxe   products are VOC-compliant throughout California: Cetol 1 RE, Cetol SRD RE Transparent, Cetol SRD Semi-Transparent Wood Finish and Rubbol® Solid Wood Finish.

Q:I don’t want to rent a power washer for the cleaning procedure. Is a garden hose OK to use?

A:No. The use of a garden hose, even with a nozzle, will not properly remove the mill glaze, dirt, pollution, old coatings, etc. that may be found on the surface. We have found that using a cleaning solution of 4 ounces of TSP, 1 quart of outdoor bleach and 3 quarts of fresh water, followed by a power washing at 500-800 PSI is an effective way to clean wood without having to hand scrub or sand the entire surface.

Q:I have an exterior door that has been coated with Cetol 1 RE. I want to put an acrylic/urethane coating as a top coat. Is there a problem with that?

A:We do not recommend that type of product because it loses its flexibility and does not offer the durability and protection of Cetol Door and Window or Cetol 23 PLUS RE.

Q:I want to fill the nail holes on the outside of my house. I bought filler and would like to know if I can fill the holes with a mix of PPG ProLuxe and wood filler.

A:Without extensive testing we cannot tell whether the filler powder and PPG ProLuxe are compatible with each other. For this reason, we recommend to fill all joints, cracks, and nail holes with a good quality polyurethane or acrylic filler prior to coating application. Areas where caulking is smeared over the wood surface can be sanded after drying with 80-grit sandpaper to remove the caulking residue. It is important to remove caulking smears because the pigments in the Cetol finishes won’t penetrate and will appear lighter in color.


Q:I would like to paint my picnic table. What PPG ProLuxe  stain would you recommend?

A:If you are looking for a painted appearance to the picnic table, we recommend Rubbol Solid Wood Finish.

Q:What PPG ProLuxe  products can be applied on a fiberglass door?

A:Both Rubbol Solid Wood Finish and Cetol Door & Window can be used on a fiberglass door.

Q:Is it OK to add pigment and/or other products to PPG ProLuxe  finishes?

A:No, we do not recommend adding anything to our transparent products. The PPG ProLuxe  Rubbol Solid Wood Finish and Cetol SRD Semi-Transparent Stains can be tinted in store using universal tints available at PPG ProLuxe  suppliers. No other additives should be used with any PPG ProLuxe  products, as they could possibly slow down drying time, change gloss levels and affect product performance.


Q:We have a new western red cedar fence and would like to use the PPG ProLuxe  stain Cetol SRD RE. Would this be the recommended system?

A:Yes, one coat of Cetol SRD or SRD RE can be used on fences after proper surface preparation. The Cetol SRD or SRD RE can be brushed, rolled, or sprayed on. If sprayed or rolled, however, the application should be back brushed.

Q:What’s the difference between Cetol and Rubbol ?

A:Cetol finishes are transparent and semi-transparent products that enhance the natural appearance of exterior and interior wood surfaces. Rubbol stains offer superb adhesion and color retention in an opaque coating.
