Wood Clear Coat for Outdoor Use

Imagine you are refinishing wooden outdoor furniture or other wood items that are located outdoors. You’re looking for a transparent, non-colored wood clear coat and you want it to provide a glossy finish. It’s important to you that the clear coat is durable, will protect the wood against moisture damage, and will not degrade when exposed to sunlight. It’s also especially important to you that the clear coat be easy to apply.
A coat of quality wood clear coat on your outdoor wood items can be the difference between a long, beautiful lifespan and one that has been shortened by time and exposure to the weather. With so many wood clear coat options available, what type should you choose?

The primary things often considered about a wood clear coat is its ability to avoid yellowing, cracking and peeling over time, dry time, and ease of use. For outdoor use, polyurethane and urethane clear coats are popular as they best meet these criteria, but with some exceptions.

Both polyurethane and urethane wood clear coats can avoid yellowing, cracking, and peeling, but in differing degrees, depending on the formulation used by a particular manufacturer.

Dry time and ease of use of polyurethane and urethane clear coats can differ depending on whether it is a 1K (one part) or 2K (two part) formulation. 1K describes a coating that does not require a hardener, catalyst or activator to harden. Once the clear coat is applied to a surface it will dry without any additives. 2K describes a coating that does require a hardener, catalyst or activator to cure. Without it the clear coat would never fully dry. 2K clear coats take a longer period of time to dry to the touch and fully cure as compared to 1K formulations. As 1K formulations don’t require mixing in a catalyst they are more user-friendly than 2K coatings. So, 1K wood clear coats best meet the criteria of quicker drying time and ease of use. They are frequently less expensive as well.

Another consideration for outdoor wooden furniture and other wood items is expansion and contraction of the wood caused by precipitation and humidity. The molecular bonding properties of urethane clear coats make them more flexible than polyurethane clear coats. Therefore, in a high moisture environment they can stay adhered to the wood surface without cracking and peeling better than less flexible polyurethane coatings. Which brings us to KBS DiamondFinish Clear.

DiamondFinish Clear is a 1K moisture cured urethane clearcoat that is that is UV stable, durable, and extremely tough. It can perform in the toughest of environments without yellowing, cracking or peeling. With minimal surface preparation, DiamondFinish Clear can be applied directly to wood (Likewise, it can be applied to ferrous as well as non-ferrous metals including aluminum, alloys, brass, chrome and copper). It’s also perfect as a high quality clearcoat when applied over cured basecoats, standard solid color paints, and single-part or two-part paints. Because of its Advanced Cross-Linked Coatings Technology, it is both flexible and durable so it doesn’t have issues with delamination or peeling away from the surface. For a demonstration of DiamondFinish Clear’s flexibility and durability see our video.

Car Frame Repair is Kept Free of Future Corrosion Using the KBS Ultimate Frame Coater Kit

During an automotive restoration car frame repair is often necessary. During the life of the car, or truck, the frame may have been damaged by rust or a collision. Since a damaged frame affects safety, it is important to be sure the frame is repaired properly. The first step of a car frame repair is a thorough inspection of the frame to determine if it has any damage.

In cases of collision a frame may be visibly bent, however, there are times when the damage may not be visible. This might be noticed if the vehicle is pulling to one side as it is being driven. If an alignment is performed and the car is still pulling, there is a good chance the frame is bent. Uneven tire wear is also an indicator of a bent frame. Again, if after an alignment is performed and the condition persists, the frame may be bent. Another sign of a bent frame are shocks and suspension that are worn unevenly. These components will wear faster on the side of the vehicle where more weight is being distributed by the bent frame. Uneven gaps in the body can also be a telltale sign of a tweaked frame and need for car frame repair.

To straighten the frame, autobody shops use powerful hydraulic machines to push and pull the frame back into shape. That is, if the car or truck hasn’t been too badly damaged. In this case, car frame repair may be possible by cutting out the bent portions of the frame and weld in replacement pieces.

Another consideration are cracks in the frame that have formed due to collision, or stress from long-time use. Cracks can be visible to the naked eye, however, some are hard to see or are hidden just below the surface of the metal. Also, visible cracks may have ends that are so narrow that it is difficult to see how far they extend. There are methods to find these small cracks in the metal. The first is visible dye penetrant testing where dye is applied to the metal surface. After a period, the dye is wiped off the surface, which leaves dye that has settled into the crack. Therefore, making the crack visible as a bright red line. The only drawback is that the test will only show cracks that have reached the surface. It won’t show internal cracking of the metal.

Dye penetrant testing indicates cracked metal

A different and more accurate way to test metal for cracks is magnetic particle inspection, which is commonly known as Magnaflux. This process detects cracks that are on the surface as well as defects in the subsurface of the metal. The way it works is magnetic particles, suspended in oil, are applied to the surface of the metal. The metal then receives a magnetic charge causing the magnetic particles in the oil to concentrate where cracks or defects in the metal are and indicate where they are located. Of note, Magnaflux is significantly more expensive than visible dye penetrant testing for car frame repair.

Magnetic Particle Inspection reveals crack

Cracks in frames must be expertly repaired. Common car frame repair methods for flat surfaces include reinforcing the crack with a square shaped plate with the square edges of the plate placed 45° to the crack, which spreads the stress forces out. Another method is to “stop drill”, or drill holes at ends of the crack to keep the crack from migrating, and then installing a sleeve over the cracked area and welding it in place.

Rust is common cause for significant frame damage. Especially with cars driven in the midwest and northeast US, where road salt eats away at metal. Rust damage is usually easily spotted with a visual inspection of the frame. However, frames can rust from the inside out, with little evidence of rust on the exterior of the frame. So, it’s important to inspect inside frame rails to be sure this isn’t happening. Also, the welds throughout the frame, including joints of mounting tabs welded onto the frame, need to be carefully inspected for rust damage that may have compromised the integrity of the metal.

The rust needs to be removed physically, or chemically, and perforated or significantly damaged metal needs to be replaced. Welded-in steel plate patches may work in some cases while in more extreme situations new frame sections can be purchased or obtained from donor cars.

Once a frame has been inspected, and any needed car frame repair made, it should receive a coating that will keep it protected from rusting in the future. KBS Coatings offers the Ultimate Frame Coater Kit to remove rust, prepare the metal for coating, and seal it away from future corrosion.

The first step in the process is to remove any loose, flaking rust with a wire brush or wheel, or sandpaper. KBS Klean is then used to clean the metal. This high-strength non-toxic cleaner removes dirt, grime, grease, and other contaminants from the surface of the metal. KBS Klean can also be used to clean the frame during frame inspection and car frame repair.

The next step is RustBlast, which removes rust and is applied with a scrub brush and allowed to soak for at least 30 minutes. RustBlast contains zinc phosphate pre-primer and etches metal to prepare it for coating with RustSeal.

RustSeal is then applied with a brush, roller, or spray-gun. RustSeal is a single part coating that is hard and durable, yet flexible to handle impacts and dings. It effectively seals the metal away from air moisture and therefore keeps it from rusting. RustSeal provides a beautiful finish, and if flows out well. Which means it smooths out when applied and doesn’t show brush marks. RustSeal looks great and compliments any show car or restoration.

A final, yet crucial step is to protect the inside of frame rails from rust. To do so, the kit includes Cavity Coater, which is a cavity wax and corrosion inhibiting coating. Cavity Coater penetrates deeply to provide protection in hard-to-reach areas. Cavity Coater is applied with the Cavity Wand, which has a 360 degree spray tip for complete coverage.

Proper frame inspection, car frame repair, and corrosion protection are an important part of an auto restoration. The KBS Ultimate Frame Coater Kit ensures the frame will stay in rust-free condition, and looking great, for years to come.

Clear Concrete Sealer – How to Choose the Best Type for Your Project

A clear concrete sealer serves two primary functions. One is to protect the concrete and the other is to improve its appearance. Concrete surfaces, especially garage floors, are subject to staining and damage from oil, chemicals, dirt, road salt, and other materials. They can also be damaged by water erosion and extreme temperatures. A clear concrete sealer provides a protective barrier that stands between damaging elements and the concrete to help keep it from spalling, pitting, and cracking. Although there is the initial investment of time and money to seal concrete, ultimately, it will help to avoid the expense of repair or replacement of the concrete by extending its service life. Concrete sealers can be used on new and old concrete, whether indoors or outdoors.

A clear concrete sealer also helps to beautify concrete by bringing out its colors and textures with a low sheen, high-gloss or wet look finish. Of note, spills, mud, and other contaminants are more easily cleaned from a sealed concrete surface.

Choosing the best type of clear concrete sealer depends on the requirements of your project.

Acrylic Concrete Sealer

Water based acrylic concrete sealer is the most widely used and is known for its color enhancement, short dry time and the ability to be applied to concrete soon after it is poured. Acrylic concrete sealers are also easy to use and more economical than other concrete sealers. A downside is that acrylic concrete sealer applies in thin coats is not durable. So, recoating is required more frequently than other types of clear concrete sealers. Acrylic concrete sealers are available in water based and solvent based formulations. Water based is often preferred as it is more durable than solvent based. Additionally, it helps reduce issues like brush marks and bubbling. A benefit of a solvent based acrylic clear concrete sealer is that it does a better job of enhancing the concrete color.

Penetrating Concrete Sealer

A clear concrete sealer that penetrates concrete is popular for outdoor use as it absorbs into the concrete for a barrier that doesn’t let water in but allows water vapor to evaporate out. This is ideal for winter environments as water trapped in concrete can freeze and expand, thereby cracking the concrete. Penetrating concrete sealer is popular for outdoor use, such as on sidewalks, as it doesn’t have a glossy finish that can get slippery when wet. Types of penetrating concrete sealers are silicate concrete sealer, silicone concrete sealer and silane concrete sealer. Silicate concrete sealer increases hardness and density of concrete. It maintains the natural appearance of the concrete but doesn’t provide high levels of protection against water erosion. Silicone concrete sealer provides shorter term protection and will need to be reapplied far more frequently than other sealers. This sealer doesn’t alter the appearance of concrete and is often used on vertical surfaces to protect concrete against graffiti. The coating doesn’t offer UV protection so it’s not ideal for applications that are exposed to significant sunlight. Silane Concrete Sealer is applied in two to three thick coats and provides protection for up to 3 years. This heavy-duty clear concrete sealer significantly changes the appearance of the concrete and is frequently used for parking garages.

Epoxy Concrete Sealer

Epoxy clear concrete sealer is much harder than acrylic concrete sealant and offers a thick and durable finish that is long lasting and abrasion resistant. Epoxy sealant has a high gloss and brings out surface colors. It’s a popular choice for kitchen counters and high traffic areas like walkways. As epoxy is vulnerable to yellowing caused by UV light it is most popular for indoor applications.

Polyurethane and Urethane Concrete Sealers

Polyurethane and urethane clear concrete sealer has a service life of 4-8 years, provides almost twice the thickness of an acrylic concrete sealer, and offers excellent durability against chemicals, contaminants, and scuffing. UV protectants keep the sealant from yellowing over time, making it a functional choice for outdoor applications as well as indoor use. Like acrylics, they are available in water based and solvent based formulations. This type of sealer performs so well it is the sealant of choice for high traffic areas such as concrete roadways. Flexibility of the coating allows it to handle impacts that would damage an acrylic clear concrete sealer.

KBS Coatings DiamondFinish Clear concrete sealer is an excellent choice for sealing concrete. DiamondFinish Clear is a 1K (one part – requires no mixing) moisture cured high gloss urethane clear coat that is exceptionally tough. Its formulation brings out the colors and textures of the concrete and because of its Advanced Cross-Linked Coatings Technology, it is both flexible and durable to avoid cracking and peeling.
