Frequently Asked Questions - Sansin

Can I use SDF over Classic?

Answer: Yes, but this is not recommended for siding 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?

Answer: 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?

Answer: 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.


How do I dilute colour?

Answer: Use the Clear UV formula with the respective product to dilute colour or increase clarity. Naturals should not be diluted more than 20% using the appropriate Clear UV formula. For example, use Classic Clear UV to dilute Classic Light Natural


Can I apply more than one coat of SDF on my deck or siding?

Answer: Apply up to two coats on decks and siding. DO NOT apply more coats as this could form a film.


My stain is not the colour I expected, what can I do?

Answer: Adding the respective Clear UV formula will lighten or increase clarity; or, order a different colour to mix in with your existing product to create the colour you desire; or, return the product to a SANSIN colour CENTRE DEALER for adjustment.


Paint & Stain Remover: How do I use it inside?

Answer: 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?

Answer: 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?

Answer: 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?

Answer: 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.


Why do some Sansin products need to be coated with Clear UV where as others do not?

Answer: Clear UV in its respective product has considerably stronger UV resistance and is normally used as the last coat to avoid strengthening colour. Sansin Classic and Dec formulas require 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 colour while building up the necessary protection.


When do I maintain my surface for optimum performance and colour retention?

Answer: A maintenance coat is required when surface erosion becomes visible, or when the surface colour lightens noticeably. Erosion may first become apparent on the grain whereas colour loss typically shows first on southern exposures.


What kind of coverage can I expect from my Sansin product?

Answer: 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 3.7 litres per 18-27 sq ft. per coat of Sansin Dec whereas a one-coat formula like Sansin SDF could use up to 3.7 litres gallon per 9-18 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?

Answer: 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?

Answer: Breathability, ease of maintenance and sustainability.


What is the difference between Classic & Dec?

Answer: 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?

Answer: 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 2x4 - 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.
