OSI Quad Max Sealant Review: The Best & Most Advanced Caulk

With growing interest in our past caulking articles, we felt compelled to dive further into discussing one of the absolute best caulking in today’s market.

This time we will cover the best house caulking and sealant that money can buy, not merely for house painting but for any application. Be mindful, ratings within this article are primarily based on durability – but fret not, we will cover ease of use as well.  

In the realm of house painting, there is a lot to be desired for caulking. Most large paint manufacturers create cheap in-house versions purposely designed to fail over time to provoke future sales.

 So, understanding these tactics, in our findings, it’s no surprise, the best caulking products primarily derive from smaller companies such as OSI that mainly produce caulking, sealants, and adhesives.

We will highlight the leading caulk and sealant brand that, in our experience, offers the best caulking that money can buy! 

Quality Caulk Sales & Marketing

Whether you are painting, installing windows, or sealing any interior or exterior surface, caulking is a vital sealant. The strength of the sealant’s bond, flexibility, and durability often will directly determine how long whatever you are sealing will hold up. 

If you are reading this article, chances are you are inclined to research before purchasing, and that’s a great thing! If you can pair that desire with a general idea of sales and marketing tactics, even better! Briefly, here is an example of what we mean!

For suppliers, future sales are just as important as current sales. So, an element of planned obsolescence is involved when purchasing mass-produced products, especially those pertaining to home maintenance, such as caulking. 

If you are a homeowner who has had a conversation with either a contractor or any home improvement personnel, you have likely already heard the proverbial saying, “it’s just something that needs to be maintained every few years”? 

The truth about caulking is there are caulking products and materials that last longer than others. But widely, premium caulking brands are rarely used by local painting contractors. Why is this so?

One of the leading reasons is the ease of use or lack thereof. Another factor is that conventional premium caulking is more toxic and increases human health risks involving contact with the skin or body.

We suggest wearing gloves during all caulking applications. Always follow the manufacturer’s complete safety recommendations before applying any sealant or caulking. Most existing caulking today deems some level of health risk, but solvent-based caulking can offer more risks than its counterparts. 

Outside of painters’ preferences, the culprit for a quality caulk imbalance involves paint companies dominating the market and limiting the availability of premium caulking. 

Companies such as OSI provide premium caulking options, specializing in creating a variety of premium sealants. Most importantly, OSI is not controlled or influenced by the paint or coating industry.

OSI Premium Caulking & Sealant Performance

If you are a contractor, chances are, you have heard of Quad caulking. OSI, a company originating in the Midwest of the USA, continues to expand and influence sealant standards! 

OSI is dedicated to providing premium sealants that are durable and advantageous under the most severe conditions during application. 

We are astounded by OSI’s Quad Max in particular. Quad Max has similar adhesion properties found within construction adhesives, is paintable, and offers over 300 color selections! 

This premium caulking can be applied to wet surfaces, in below-freezing temperatures, underwater, and on surfaces over one hundred degrees without issue. 

Shortly after application, conventional caulking requires painting to prevent UV damage and mitigate mold growth. On the other hand, Quad Max is formulated to withstand all weather conditions without the need to paint or treat sealed areas.

OSI Premium Caulking & Sealant Advantages

For some, extreme adhesion is reason enough to distinguish and ultimately purchase Quad Max over other sealants. In our findings, the critical attributes of Quad Max are not limited to adhesion or impervious properties. Q Max offers an unmatched ability to remain durable, retaining both its strength and flexibility like no other sealant. 

Furthermore, we found OSI’s tinted caulking solutions to provide minimum discoloration and oxidation. Tinted sealants remain ductile and in-tack on projects where sealants were applied over 15 years ago. 

Sealant color options and nearly limitless application requirements are advantageous to siding contractors, especially for JameHardie ColorPlus installers. 

For painters, OSI caulking eliminates the need for pre-primed surfaces to promote adhesion before caulking. 

Window installers can use OSI sealant systems to seal, color match, and fill empty wall cavities that may exist around the window. 

Best-Sealant-Raleigh-Foam

OSI provides complete sealant systems for several trades. These premium products revolutionize how painters, trim carpenters, window & door installers, and builders utilize and approach modern household caulk applications and systems. 

Remaining highly versatile, OSI is the leading company – providing complete systems ranging from flashing taps, foam, construction adhesive, sealants, and more! Furthermore, OSI Quad Max adheres to several construction materials, including OBS, wood, aluminum, vinyl, steel, composites, and glass.

If you fall into either trade category previously mentioned, we highly recommend testing OSI products out for yourself.  

OSI Certified Installation Program

OSI also offers a certification program that is taking a stronghold in the window and door installation industry. This program is beneficial to both the installer and the client. 

When contractors are OSI certified, clients know their installer prioritizes premium quality and practices properly specified installations when using specified OSI tapes, flashing, foam, and sealants. 

When you hire an OSI-certified contractor, OSI also provides a 15-year fail-proof warranty that covers the materials and, in some cases, will receive a payment for potential damages. The warranty is provided for any manufacturer. 

The steps to the certification involve an initial training that teaches installers proper installation steps. After this initial training, there is a 16-module training program. Once the training is completed, installers become certified. 

Further training includes versing installers on the anatomy of doors and windows. This additional training helps to understand where potential fail points are and assures these areas are correctly installed to alleviate future failures and leaks for years to come.

98% of window and door failures are due to improper installation. So, OSI’s certification program could be beneficial. For further and more current details, please refer to OSI’s website. 

The Grand Finale

OSI makes quality caulking and sealants overall. For this reason, we recommend OSI for several applications. Maybe we will use OSI caulking on your next installation.
