Different sealants are available for different materials, such as decks, concrete, tile grout, and walls. They protect from water and sun damage, stains, and cracking caused by extreme weather conditions. Users should ensure the surface is clean and dry before applying the product.
Different materials often require different sealants, so it should come as no surprise that different types are available. Most vary on the materials they are best at sealing with, which usually includes materials found in a typical home. Some of the more common types of sealants on the market include those for decks, concrete, tile grout and walls.
A deck sealer typically is best for exterior wood. His specialty is to improve the durability of wood by fighting decay over time. It is usually clear so that the natural beauty of the wood can shine through. Not only do deck sealers typically protect wood from water damage like mold, they should also protect it from sun damage. A penetrating deck sealer is absorbed into the material, while a film-forming sealer creates a barrier around the wood.
Concrete sealers work similarly to those intended for decks, but work better on concrete. Although concrete usually lasts a long time, a sealant designed specifically for this material can extend its life even further. One of the main points of a concrete sealer is to protect it from extreme weather conditions, such as expansion and cracking often caused by melted ice and rain. It can also protect concrete from salt, chemicals and stains. Such sealants can be clear or colored and are often petroleum or water based.
Some homeowners choose to put their tile in or at least do the maintenance themselves. Those who choose to do this are typically advised to seal the grout between the tiles. There are specific sealers for this purpose and they are usually known to keep the grout looking new and attractive. Some grout sealers do the vital job of protecting the area from stains and mold and can be sprayed onto the surface. On the other hand, some heavy, more expensive types can protect the grout from serious stains, such as grease.
Small cracks in a thick wall can be repaired with a polyurethane sealant. This type of sealer is usually the consistency of grout and is known to expand rapidly after application. Fortunately, it is also flexible and stretchy and can protect walls from water damage.
Almost all sealants require users to make sure the surface is clean and dry before applying the product. Also, most sealant manufacturers recommend applying sealants to an inconspicuous test spot first to avoid accidental staining of the area. In fact, reading the instructions on the tube or bottle is usually a good first step to most home improvement projects involving sealants.
