What are some key preparation steps?
Inspect wood surfaces for defects and make any necessary repairs. Use Sansin cleaners and/or wash the entire surface with a pressure washer using clean water. Sand the surface well using a 60-80 grit paper and a variable speed orbital sander (see product data sheet for any variance on grit paper). Follow by power washing, vacuuming or using compressed air for proper cleaning. Surface must be clean, free from dust, dirt, grease, wax or any existing coatings.
What can I do to make sure the coating penetrates well?
First, always make sure to read the product data sheet (PDS) carefully. Specifics on prep and application are on the PDS. But in general, since Sansin stains are water-borne, you want to always flood surface to the point of saturation. You want the first coat to penetrate. The key is proper sanding (see above and PDS) and then, don’t forget to stir the product well before and during the application process and apply in proper conditions with an ideal temperature of 21°C (70°F) and relative humidity of approximately 50%. Do not apply if rain or near freezing temperatures are expected, and do not apply on wood that is warm to touch or in direct sunlight.
After flooding the surface through brushing or spraying (see PDS for advice), brush out any puddles and runs and level the finish. Apply a second coat for added protection.
Can I use SDF over Classic?
Yes, but this is not recommended for logs that see excessive wetting or surfaces that demand a coating that breathe freely such as logs and larger timbers. Always wash using Sansin Multi-Wash as preparation for the new or maintenance coating.
Can I mix Classic and SDF in the same can?
No, the base formulas are inherently different. Although they may appear to be compatible, we cannot guarantee performance results.
Will adding more water to my Sansin EnviroStain affect its quality?
Adding water will reduce the quality of the product. If you still wish to add water (e.g.. for ease of spraying) than add NO MORE than 5%. Always add water to stain rather than stain to water.
Can I apply more than one coat of SDF on my deck or siding?
Apply up to two coats on decks and siding. DO NOT apply more coats as this could form a film.
Paint & Stain Remover: How do I use it inside?
It should not be used inside, the residue is to difficult to remove without rinsing, we recommend only using it outside
Aqua-Gard: can I use it over painted concrete?
Aqua-Gard needs to penetrate into the surface to be effective – this is what allows it to remain breathable. Aqua-Gard is not designed to perform on top of paint or coatings.
Drips: how do I control them?
When applying exterior Sansin coatings we recommend completely saturating the surface with product to the point where it will absorb no more. This will naturally cause the product to slightly run. Then, as per Directions For Use, back brush the surface to eliminate any streaking by spreading the runs and drips evenly.
How long will my Sansin product last?
Base performance is indicated on product Directions For Use. Individual product performance depends on a variety of factors such as exposure, wear and tear, quality of application, quality of wood and location. Your local representative may be able to provide a more specific product estimate.
Why do some Sansin products need to be coated with Clear UV where as others do not?
Clear UV in its respective product has considerably stronger UV resistance and is normally used as the last coat to avoid strengthening color. Sansin Classic formula requires three coats to achieve complete saturation of the wood cell to create a water repellant surface; Classic Clear UV is normally used for the third coat to maintain a clear light color while building up the necessary protection.
When do I maintain my surface for optimum performance and color retention?
A maintenance coat is required when surface erosion becomes visible, or when the surface color lightens noticeably. Erosion may first become apparent on the grain whereas color loss typically shows first on southern exposures.
What kind of coverage can I expect from my Sansin product?
There is no standard answer because coverage varies depending on the wood species in question. With exterior coatings, it’s best to get as much product into the wood as possible. A cedar deck could use an average of 1 gallon per 200-300 sq ft. per coat of Sansin Dec whereas a one-coat formula like Sansin SDF could use up to 1 gallon per 100-200 sq ft. Pricing is dependant upon the selected formula – see the appropriate product Directions For Use for more details.
Why is Sansin more expensive than some competitive products?
Sansin uses the finest pure resins and ingredients, with no cheap fillers or paraffin – incorporating the best UV-protection technology available. Sansin is a premium, environmentally-friendly wood coating that protects wood while allowing it to breathe. Plus, Sansin’s exceptional ease of maintenance means trouble-free beauty for your home for years to come.
What are the benefits of a non-film forming product vs. a film-forming product?
Breathability, ease of maintenance and sustainability.
What is the difference between Classic & Dec?
Dec is designed for horizontal surfaces and Classic for vertical surfaces. The formulas are compatible but Sansin Dec has a lower solids content plus performance characteristics that allow for easier penetration on a horizontal surface.

Can I just have one product for all my surfaces?
No. Different surfaces can demand distinctly different characteristics from a coating. For example, a large mass of wood such as a log naturally retains more moisture than a 2×4 – which in turn means it will decay unless the wood can breathe. A deck needs more water repellency and UV protection than a wall. Sansin has a family of products designed for optimum performance depending on the characteristics of the wood surface in question.
