SASHCO - CASCADE FINISHING CLEAR TOP COAT FAQ'S
 
Sashco Cascade Stain

 

faq's



Are water-based products bad?

If by “bad” you mean poor performing, no. Some water-based coatings (like our Capture Log Stain / Cascade and High Sierra) will perform very well if good surface preparation is done and if they are applied in appropriate weather. On the other hand, it is also true that solvent-based coatings (oil-based stains) are more forgiving when less-than-excellent surface preparation is done and when the weather is not as ideal.

Can I apply Cascade by itself?

No. Cascade should not be applied by itself, unless re-coating over Capture Log Stain. Cascade has additives to prevent attack from ultraviolet light, but these additives are not nearly as efficient in protecting the wood surface as the pigments we add to Capture Log Stain.

Can I mix the Cascade and Capture Log Stain?

No, mixing the coatings will reduce the performance of both.

Can I put Cascade over another product?

Depending on what that product is, yes. Cascade will work over most water-based coatings and over some oil-based coatings. The best way to find out if it will work is to test an inconspicuous spot on the home. If the Cascade wets the surface and doesn’t “fish eye” or bead up, you’re most likely OK to go. Be sure to check with the manufacturer of the other product to ensure that there are no problems covering up their products with the Cascade.

Can I put Cascade over High Sierra or Transformation?

Yes. And in fact, Cascade will help add some life to your stain, helping you avoid having to re-coat with the High Sierra or Transformation as often.

Can I put High Sierra over Capture Log Stain / Cascade?

Yes. The surfaces need to be clean and sound, with all other appropriate application procedures followed.

Can I put Sashco's Capture / Cascade over High Sierra?

Yes. The surfaces need to be clean and sound, with all other appropriate application procedures followed.

Can I tint the Cascade?

Yes, but it is not recommended because it is very hard to achieve color consistency.

Can I use Transformation over top of Capture Log Stain or High Sierra?

If the Capture Log Stain Log Stain or High Sierra are in good shape, meaning there are few, if any, areas of bare wood and little discoloration, it is best to stick with what you started with, followed by a coat of Sashco’s Cascade top coat every year or two. If, down the line, one has to completely strip the home down to bare wood, it would then be OK to use Transformation to re-stain. It is not advisable to use an oil-base over top of a water-based coating because most water-based coatings are much more elastic than oil-based stains. As the logs move and breathe, the oil-base stain will be more rigid than the water-based stain and may cause the water-based product to peel under the pressure of being pulled with normal log movement.

Do I have to use Cascade? Will Cascade rejuvenate my existing stain?

Yes when using it in conjunction with the Capture Log Stain Log Stain. Here’s why:

a) The relatively tacky surface of Capture Log Stain, which is due to its elasticity, can pick up lots of dirt without Cascade (which dries a little harder than Capture Log Stain).

b) When Cascade is applied over Capture Log Stain Log Stain, it brings out the “depth” of the stain, enhancing the grain of the wood and providing a soft luster that is very attractive.

c) Cascade provides the majority of the water repellency of the system.

d) Cascade has UV inhibitors that help protect the color of the Capture Log Stain itself, which means that your stain will not darken as much over time. If a reapplication of clear Cascade is done 1-3 years after the initial application, then the overall system can be bolstered, both aesthetically and in endurance. Eventually, just reapplying more Cascade will no longer be sufficient, and at that point more colored Capture Log Stain Log Stain will be required.

When using in conjuction with High Sierra or Transformation stain, you don’t have to use it.

How do I tell when I need to reapply Cascade?

Generally, loss of sheen or variations in sheen may be an indication that another coat of Cascade should be applied to your home. An annual check of the moisture prone areas (i.e. low courses of logs) and upper curvature of your logs will often give you an indication that you need to re-coat. Wet the area in question, and if there is a color shift or an area where the water is drawn into the coating, it might be an indication another coat of Cascade is needed. Cascade can easily be applied with a garden sprayer, so an annual re-coat is not bad practice.

How does Transformation compare with all those other Log Home stains on the market?

There are many other stains directed towards the Log Home market available! Only a few of these (Sashco’s stains, and a few others out there) are truly “high performing”. Often, lower quality log home stains will look beautiful right after application, but require frequent maintenance.

All of Sashco’s stains are formulated to look great after application, and to maintain this look for as long as possible. We use the highest quality raw materials to ensure this.

Transformation requires only 2 coats of the stain itself – sprayed on and back brushed in. This makes application less time consuming. (For even more protection for your wood, you can apply a topcoat of Cascade over Transformation – this is easily applied by spraying and lightly brushing out any runs. Let Transformation dry 24 hours and then apply Cascade).

Transformation is guaranteed to be compatible with all of Sashco’s other products.

How many coats of Capture Log Stain / Cascade should I use? Why?

On the exterior, one should spray on and back brush in 2 HEAVY coats of Capture Log Stain followed by one heavy coat of Cascade sprayed on with runs brushed out. When the product is applied heavily it is able to build sufficient film thickness to protect the wood and provide several years of good performance. One coat is generally too thin, leading to less durability, which means more frequent re-staining will be necessary.

On the interior, one coat either brushed or sprayed on is sufficient, followed by one to two coats of the Symphony clear coat.

If Capture Log Stain collects a lot of dust on the interior, won’t it do the same on the exterior?

Capture Log Stain alone will remain relatively tacky compared to Capture Log Stain that is also top-coated with Cascade. A coat of Cascade on the exterior, or Symphony on the interior, will greatly reduce or eliminate this problem (plus enhance the overall appearance dramatically).

What fungicides can I use with Sashco's Capture / Cascade?

Sashco’s laboratory has done limited testing of the various commercially available fungicide additives. Many of our customers have had success using such products as “M-1 Additive”, “Stay-Clean I/E”, “Super Mildex”, and “Di-All MC-2.” But, it must be mentioned that Sashco’s fungicide testing is not extensive, and there is always a possibility of color shift or other product incompatibility using additives in combination with Capture Log Stain or Cascade.

What is better about oil based stains than water based stains?

Both oil-based and water-based stains perform very well if the wood is prepped well and is dry. Transformation (Sashco’s oil based stain) is specifically formulated for log home restoration. Here’s why: a homeowner often doesn’t know which stains have been used on the home in the past. In this situation, Transformation stands a much better chance of compatibility than a water-based stain.

For new construction, both water-based and oil-based stains are good choices. There are some people who strongly prefer oil-based stains – perhaps they have more experience with an oil bases, etc. For them, Transformation is an excellent choice for new construction. We have formulated Transformation with one of the highest quality resins available and have loaded it with UV inhibitors. This product is formulated specifically for log homes to accommodate extreme log movement and mountain weather.

For customers who prefer the easier clean up and environmental advantages of a water-based stain, our Capture Log Stain / Cascade system will give superior performance. Like Transformation, Capture Log Stain and the Cascade topcoat are formulated with the highest quality resin and loaded with UV inhibitors to afford excellent performance on log homes.

Remember!! Careful wood preparation (i.e. corncob blasting or thorough power washing) and dry wood check by a moisture meter are CRITICAL to any stain’s performance – oil- or water-based.

What is the best way to apply Sashco stains?

It's best to apply them with an airless sprayer with a Graco 313 or 515 tip (or the equivalent in a different brand). One should spray on and back brush in 2 coats of the stain (High Sierra, Capture Log Stain Log Stain or Transformation), and when using Capture Log Stain Log Stain, it must be followed by 1 coat of the Cascade sprayed on, with any runs being brushed out. Make sure to thoroughly read through the individual product data tec for more detailed information or contact Sashco for the appropriate documents.

NOTE: Cascade can be used over top of High Sierra and Transformation and is especially recommended for maintenance purposes; however, it is only necessary at initial application with Capture Log Stain.

Why can’t I use Cascade on the inside of my house?

Cascade was designed for exterior use. It is a “beefy” product formulated with mildewcides and fungicides, not appropriate for interior applications. Our product, Symphony, is an interior clear coating formulated to enhance the beauty of the interior wood by giving it what is called “depth of image”.

Why is Transformation the stain of choice for rainy, humid climates?

It is generally true that for rainy, humid climates (like the coastal areas of Washington and Oregon), an oil-based stain performs better than water-based stains. The reason is because when log surfaces remain wet for long, sustained periods of time, this unrelenting wetness can have a more negative affect on many water-based resins than oil resins, which are generally much less sensitive to sustained moisture exposure. When the wetness is more intermittent, then water-based stains can often perform as well or even better than oil-based coatings.

Despite this, we have many customers in humid rainy climates that have been very successful using our water-based Capture Log Stain / Cascade stain and our High Sierra stain. As always, excellent surface prep and proper wood moisture content prior to staining is critical.

Will the Cascade flake?

No, generally Cascade will erode and weather off over time rather than flake. The only time you might see flaking or peeling is if there was excess moisture behind the Capture Log Stain and Cascade to begin with, which is now vaporizing, pushing out of the logs and pushing the Capture Log Stain and Cascade off the wood, which gives the appearance of flaking.
