Other products include ChimneySaver RTV, Brick & Mortar Cleaner, ChimneySaver VOC Compliant Solvent Base Water Repellent, and Crack and Joint Sealant.

ChimneySaver’s list of products goes on and on, however, we’re more interested in one; the ChimneySaver Water Repellent.

Does ChimneySaver Work?

This product is one of the highly recommended water repellent products for chimneys.

ChimneySaver consists of a photo-reactive chemical. The benefit of this constituent ingredient is that it gives this product its vapor permeability.

In other words, while repelling water from soaking it, it also allows trapped moisture to escape.

With ChimneySaver, most forms of moisture-related chimney damage are addressed. That includes water stains, spalling, freeze-thaw damage, chlorine attacks, and loss of insulation value.

Other problems that are prevented include acid rain damage, corrosion, deterioration, and efflorescence.

What More?

As a penetrating volatile organic compound (V.O.C) compliant water repellent, ChimneySaver Water-Base Water Repellent contains siloxane. This gives it its masonry-penetration feature.

This water repellent product penetrates as much as ¼ inch of the chimney masonry surface. This could even go deeper depending on porosity.

When applied a chemical reaction occurs between the product, atmospheric moisture, and masonry minerals to form a strong and permanent bond. This serves to lock out moisture from getting in.

At the same time, water vapor contained within masonry is allowed to escape out.

Due to such characteristics, ChimneySaver Water-Base Water Repellent can be said to have the ability to breathe. You get to benefit from the brand’s 10-year warranty for its products.

Plus, it has efflorescence protection and can be used on a wide range of masonry surfaces.

The Pros of Using ChimneySaver Water Repellent

While we’ve listed some of the many benefits associated with ChimneySaver Water-Base Water Repellent use, other clear benefits stand it out from other similar products.

Several other waterproofing products create a water seal on masonry surfaces.

When this happens, damage caused by moisture is further aggravated as vapor trapped in masonry is unable to escape. This leads to a never-ending freeze-thaw cycle that steadily deteriorates masonry.

This is totally different for ChimneySaver’s Water Repellent.

As explained earlier, this product has a semi-permeable membrane that serves to let out vapor. This ability to breathe makes it one of the best chimney water repellents to use.

According to the manufacturer, consistent testing has seen it outperform acrylics, siloxanes, resins, and silicones.

Cons of Using ChimneySaver Water Repellent

Are there any known disadvantages associated with ChimneySaver Water Repellent? It depends on who you ask.

This is among the top brands which are trusted within the industry.

Is it proper to Apply ChimneySaver Water Repellent on Damp Surfaces?

This is an important question to ask because damp surfaces are laden with moisture. Moisture is a known enemy that causes all sorts of masonry issues.

Nevertheless, ChimneySaver can be applied on such damp surfaces with no problems resulting.

Ordinarily, this will cause a wide range of issues for other types of water sealants. Such water sealants trap moisture, making it impossible to escape. As stated earlier, this results in all sorts of deterioration.

Thankfully, this is prevented due to the superior formulation of ChimneySaver’s Water Repellent product.

Can this be used on Other Masonry Surfaces?

ChimneySaver’s Water Repellent is both applicable on masonry chimneys as well as other forms of masonry where surfaces need to be protected from moisture damage.

Its multiple functions make it ideal for a wide range of masonry-related projects.

More than a Surface Coating

If you’ve followed the discussion to this point, you’d have the idea that ChimneySaver Water Repellent does much more than surface coating masonry.

Its tiny molecular structure allows for deeper penetration of masonry surfaces to a depth of about ¼ inch or even more depending on the level of porosity.

That means your masonry surface will have longer-lasting protection compared to similar products from other brands. This isn’t to say that ChimneySaver is the best brand of water repellents available.

However, it’s among the top brands you can find.

Deterioration Due to Ultraviolet Light

While some water repellent products begin to give way or deteriorate under constant exposure to ultraviolet light, it’s quite different with ChimneySaver.

In other words, ChimneySaver is resistant to deterioration due to ultraviolet light exposure.

Bricks May Continue to Spall Even After Applying ChimneySaver

There’s no guarantee that spalling bricks will be instantly fixed by applying ChimneySaver water repellent. The damage previously done before application may continue due to brick delamination after a freezing.

However, continued spalling will require the additional application of ChimneySaver to arrest such. This procedure should be handled by a professional.

What Other Alternatives Are there?

If you aren’t particular about ChimneySaver Water Repellent, you may want to know what other water repellent products there are. This is a great way to go about your search.

Side-by-side comparisons of similar products help reveal the advantages or how one product measures up in comparison with the other.
