Commercial Waterproofing

There are several condominium sealants, each with its benefits and drawback. In addition, they have their unique properties and uses. The best choice depends on the application and environment.  

1. Acrylic Latex Waterproofing Sealant 

This is a good choice for most interior applications. It dries fast and can be applied over existing concrete or plaster walls. It is not recommended as an exterior waterproofing material because it is very porous. 

Additionally, it will absorb odors when exposed to air for long periods. If you want to use this sealant for an interior waterproofing project, make sure the surface is clean before sealing, then apply only one coat. 

Suppose some coating is already present to bond well. However, if you have a lot of old paint residue on your walls, it’s recommended that you remove all traces of previous coverings before applying LPW.  

2. Polysulphide Sealants 

These are great commercial sealants in Miami Beach as they can withstand high humidity and strong wind conditions. They are designed to last longer than other sealant materials. 

When used properly, they can help protect wood frame buildings. PSS also expands and shrinks less than the others, which helps them work longer. 

The downside is that PSS takes much longer to dry compared to other types of condominium sealants. Also, once they dry completely, there is no rewetting ability. PSS needs direct sunlight to cure. In addition, it does not adhere to painted surfaces. 

3. Butyl 

Butyl is a common sealant used throughout the world. It works by creating a barrier between the outside and inside environments. It can be applied over many different substrates but should never be used alone because the effectiveness decreases over time. 

It provides great insulation against cold weather temperatures and resists chemical exposure. Although it doesn’t expand as polysulfides do, it still stretches 2–3 times more than any other conventional solvent-based sealant. 

Because it contains significant amounts of petroleum solvents, it can cause severe skin irritations if sprayed directly onto the skin. On the positive side, it is easy to mix, making it perfect for contractors who don’t specialize in sealant production. 

4. Epoxy 

Epoxies are available in two forms: 100% Epoxy and Solvent Based. They come in various strengths, including hardener. As such, they may require multiple coats depending upon how thick you would like the final product. 

Epoxies are commonly used to protect wooden framing members. Unlike resin, epoxies do not stick well to new finishes, so a clean surface must be prepared for them to stick well. 

They are also flexible, so they can be easily cut to fit around structural members. Like polyurethanes, they are excellent insulators. 

5. Silicone Sealants 

Silicone seals are used for their mold release properties, fire retardancy, and ease of application. There are three main silicone seals: aliphatic, cyclic, and amino silicone.  

Cyclists are composed of a silicon atom with four oxygen atoms surrounding it. Amino silicones contain both amine and hydroxyl functional groups. The difference among these types of silicones is the length of their polymer chains, which determines their physical properties and curing rates. 

Acyclics tend to cure faster than aliphatics, while aliphatics produce higher heat resistance. The curing rate is dependent on temperature, humidity, and concentration. Silicones can be either oil-based or water-based. Oil-based ones are less dense and easier to apply than water-based ones. 

The above types of commercial sealants Miami Beach are good for most situations, but some are better suited for specific requirements. If you’re looking to apply sealants, you might want to consider some advice from a professional contractor.
