Protect wood and masonry with the right waterproofing products
Waterproofing is a smart strategy to protect decks, patios, fencing, garage
floors, wood siding and more. Water, sunlight and mildew can do serious damage
to untreated wood surfaces. Similarly, wind-driven rain and ice can pound on a
driveway and ground water can seep into your home and wreak havoc with
basement walls. There are many types of waterproofing products on the market,
but materials that protect wood and masonry are the two most common types.

Uses, Types and Application Tips
Water is essential to life, but too much of a good thing can become a powerful force for destruction. In order to prevent damage to wood and concrete surfaces both inside and outside your home, applying a waterproofing solution can help keep decks, porches, patios and basements looking great for years to come. You’ll want to learn about the different options available to treat both wood and masonry. In addition to reducing damage from water, many waterproofers also provide protection from harmful UV rays and sun damage. As another benefit, some contain pigments that can enhance the appearance of any surface with a splash of color. Discover the uses, benefits and applications of waterproofers to ensure that you find the right solution for your wood or concrete surface.
Wood Waterproofing: When moisture comes in contact with wood, cracks occur. Ultraviolet (UV) rays on wood siding are also damaging as they cause discoloration and speed up wear by breaking down wood fibers. Scratches caused by feet traffic and deck chairs, mold or mildew from leaves that accumulate in damp corners and ground-in dirt all wear down a patio or deck before its time. Even pressure treated decks can benefit from waterproofing. A two-step process of cleaning and waterproofing is your best bet to improve the appearance of wood items and prevent further damage.
Wood Waterproofers: When selecting a waterproofer, you have the option
of either oil- or water-based solutions. Oil-based products generally last
longer because they penetrate the wood more deeply than water-based finishes.
Water-based finishes, however, are easier to clean. They are also more
flexible upon application as damp wood can accept a water-based finish whereas
oil-based finishes require wood to be completely dry before applying.
Masonry Waterproofing: Masonry waterproofers prevent water from seeping
through cracks in basement walls, garage floors, patios, concrete block walls,
swimming pools and fountains. They can often prevent damage before it occurs
by providing a tough water barrier. This type of waterproofer can also be used
after water damage has already occurred. Existing water damage can be
identified by white chalky streaks on concrete blocks or walls, which are
actually calcium salt deposits that water brings to the surface. Use masonry
waterproofer inside your basement or outside a home to protect exterior
surfaces, such as driveways, sidewalks and other concrete structures, from
Masonry Waterproofers: Choosing a masonry waterproofer depends upon the
type of material you are sealing and the desired effect. True waterproofing
materials stop the flow of water through concrete, retard the transmission of
water vapor and resist radon gas. Sealants, however, are only designed to
repel water. Masonry waterproofers are available as clear, penetrating
coatings, pigmented coatings and film-forming products. All are available in
both water- and oil-based formulas.
Application Tips: Before sealing wood or masonry, you must prepare the
area for application. If wood or masonry is not properly cleaned, the
waterproofer will not adhere and won’t last. For best results, consult the
manufacturer’s instructions before beginning your project.
Clear, Multi-Surface Waterproofer: Clear, multi-surface waterproofers are used on both wood and masonry to stop water damage. However, they do not include mildewcides, pigments or UV blockers. If you apply this product to wood, it turns a weathered gray over time.
Clear Waterproofer for Wood: These products are specifically designed for wood and usually include mildewcides and help wood resist fading. Clear waterproofers enhance the natural wood grain appearance. Reapply these products every one to two years.
Tinted Waterproofer for Wood: Tinted wood waterproofers also contain mildewcides but offer greater UV protection because they contain pigment. The color or tint enhances the wood color and allows the wood grain to show through. Reapply these products every two to three years.
Clear Masonry Sealer: Masonry sealers do not provide true waterproofing qualities. However, they do repel water and allow water vapor to move through the material. Apply these products to brick, concrete, block, stucco or other masonry material.
Pigmented Masonry Waterproofer: Pigmented waterproofers are similar to stains and change the color of the masonry material while also providing waterproofing. These products can be applied to any masonry surface.
Film-Forming Coatings: These masonry products resemble paint finishes – from sheen to satin to gloss. These products resist water pressure behind the film they create when applied. Use film forming coatings to seal leaky basement walls. As masonry sealers, these products typically last the longest.
