Why does Paint Crack when you paint over sealant?

It’s important to understand what’s happening when paint cracks over a sealant. It’s probably being caused by one of these things.  Either…

  1. The paint was put on too soon or
  2. The paint isn’t flexible enough
  3. The sealant bead is too small
  4. The sealant is the wrong technology

To be clear, in both of these cases, we’re referring to a situation where the sealant hasn’t cracked…the paint has.  If you have cracked sealant, there are different things going on.  Let’s break down both scenarios.

Most caulking shrinks as it dries.  There is water (or solvent) inside the caulking that leaves the film.  When this happens, the film naturally shrinks.  Because the bead is larger in the middle and thinner on the sides in a traditional joint, it shrinks the most in the middle to yield a concave appearance.  The sealant is designed to do this.  It’s been formulated to dry even when there’s a thick bead.  Paint isn’t.  Paint is designed to dry quickly.  If you put paint overtop of a sealant that is still shrinking, it automatically forces the paint to flex.  A high-quality paint might stand a chance, but a lot of them will fail within a couple days.  That’s actually how you can usually tell that this was the problem.  If the paint cracks in the first week, it’s probably from painting before the sealant was fully dry.

When a sealant is functioning properly, it’s moving.  A lot of paints just can’t move with the sealant.  This is especially true of the “highly filled” ones like primers and flat sheens.  The flatter a paint, the more likely it is to crack when applied over a sealant.  If nothing else works, try upping your paint spec to a higher quality or higher gloss paint.  It may just solve the issue.

This can be related to “scenario #2.”   The smaller the bead of sealant is, the higher the percentage of movement that you’re asking for when it moves.  For example, pretend that our siding moves ¼” every day.  If our bead is ¼”, then the bead has to double in length to put up with the movement of going from ¼” to ½” and back.  It’s moving 100% of it’s original length.  Now imagine the same joint except we have 1/8” bead of sealant.  Instead of moving 100% every day, it has to move 200% every day.  The sealant is probably going to be ok in both cases…but the paint on top of the sealant is being asked to do the same thing.  A bigger bead of sealant will make the sealant more durable…but it will also make the paint less likely to crack. 

This one is pretty easy to diagnose.  Silicones are not paintable.  The failure won’t look like the images above…it’ll look more like this. Silicones are pretty easy to identify – they say “silicone” on the label.  If you find yourself in this situation, you’re in for a bit of a rough redo.  The process of removing a silicone is one we’ve covered before.  You can find it here.

So to ensure success the next time you are planning to paint your sealant, ensure that you use a fairly large bead, give the bead plenty of time to dry, and coat it with a high-quality paint.  You also have an alternative that could help prevent the issue in the first place.  eXact Color is designed to give you a perfectly-tinted color of sealant that you won’t have to paint.  You add the paint to the sealant instead of having to wait/come back to the job to paint it.  To learn more about eXact color, head here.

A Lexel case study-

Meet Cole.

He’s a law enforcement officer as well as a homesteader who lives in a small town outside of Des Moines, Iowa.

We found him on YouTube, invited ourselves to visit, and he graciously agreed. Cole took us around his homestead and showed us all of the places where he had applied Lexel to stop and prevent leaks.

When we arrived, we first checked out the barn where, in 2018, Cole constructed blocks out of white oak to support the door hinges and handles and to provide a nice aesthetic against the red metal barn. Cole told us that he knew he would need to somehow prevent water from penetrating the seams, but he still wanted it to be aesthetically pleasing.  So, he was after a clear sealant that would allow his careful craftsmanship to show through. At the local hardware store employee’s recommendation, he purchased Lexel and applied it where the white oak wood blocks met the metal barn. During our visit, we were able to touch, see and feel the 4-year-old Lexel and could see and feel the moisture barrier it created. The blocks of wood where the Lexel was applied were still intact and showed no signs of weathering, thanks to the Lexel’s weather-resistant properties.

Not all seams on the oak blocks looked the same, though. Some of these things were definitely not like the others! Cole explained that during application, he ran out of Lexel, and in a pinch, he decided to use a different clear sealant that he had on hand to finish the job. Cole showed us where he had applied this other clear sealant. While it may have worked short-term in a time crunch, this difference over time between the two products’ durability was obvious. Here, a picture is worth a thousand words: 

Lexel vs Competitor:

Next, Cole took us to the roof of his barn and showed us where he had sealed some skylights with clear Lexel. During installation, Cole bolted down the skylights, but also knew he wanted to seal them up tight for multiple reasons. First, he wanted to avoid water from seeping underneath the cracks where the skylight was bolted down, and second, he wanted to protect the interior of the barn from dust that gets stirred up by significant south winds which are common in Iowa. Cole showed us how the Lexel prevented any rain that hit the roof from seeping through cracks between the bolts. As we stood on his barn roof (on a non-windy day, of course), Cole physically pressed down with his fingers onto the skylight to also demonstrate where the dust would have entered the barn underneath the skylight seal had he not ensured a continuous seal using Lexel. He also noted, as he pressed with his finger, that even years after application the seal remained pliable and elastomeric underneath. He pointed and had us look closely as he showed us that we could quite literally see where the dust had blown up against the Lexel seal and stopped before getting under the window and into the barn. Pride of ownership was very apparent as Cole explained that sweeping out a dusty barn prevents him from doing other more important things on his busy homestead. 

It was such a privilege to visit Cole’s homestead and see a few of the application spots where he had used Sashco products to ensure superior waterproofing and air-sealing. Not everyone is as gracious when guests invite themselves to visit, but Cole was very welcoming, and we are humbled by his hospitality.

A Lexel case study-

A Love Story.

Lexel is for lovers, and we have a story to prove it.

It’s important for the lifespan of your RVs and campers to preventively seal any potential moisture entry points before taking them out on trips. While we always recommend inspecting and locating potential entry points before your trip to the lake, sometimes you just don’t notice a leak until it is quite literally dripping on your head (or in this case, on your card game). Sashco’s Through the Roof and Lexel are heroes in this scenario. Both of these solvent-based sealants can be applied to an active leak and won’t wash away in the rain. Their superior adhesion qualities ensure that they stick the first time to your camper or RV and don’t require frequent re-application.  

This brings us to the time that we took a little trip to Iowa to visit one of our true Lexel Junkies that we stumbled upon while scanning YouTube one day.  We spent a day on Cole’s homestead where he showed us multiple scenarios in which he had used Sashco products to maintain his home and vehicles. He then told us a story about a time that he and his fiancé were on a weekend date/getaway in their camper. During the trip, they were inside playing a game of cards when the weather took a turn for the worse and a torrential downpour began. Water started seeping and dripping from the windows on their old camper. Cole, a natural storyteller, smiled and said,” I’ll never forget it. I come out here in the pouring rain and Nicole just watching from the inside of this window making fun of me». He went on to explain that he sealed the active leak during the rainstorm- thanks to having a cartridge of Lexel in the truck.  Although he didn’t have a caulking gun handy, he grabbed a nearby stick and used it to push the plunger to get the Lexel out. Like a true hero, he saved the game of cards from becoming a soggy mess, while his fiancé chuckled and watched the fiasco in real-time from inside the camper. Cole also said that the rain actually may have helped him more easily tool the Lexel. We can’t help but wonder if Cole’s ingenuity and quick-thinking helped assure Nicole that she had chosen the right man and help seal the marriage deal (you never know, right?). The two are now happily married and Cole still has not had to re-apply the stick-applied Lexel after all these years. We think the big lesson here is to keep Lexel and a caulking gun in your camper, just in case (although Cole is living proof that where there’s a will, there’s a way).

Mike Bellevue feature

Every month we feature a contractor, business, or success story. Learning from others in the biz is the best kind of learning. Today, Mike Bellevue shares a few of the inside secrets to Chewelah Painting’s success.

This month, we are featuring Mike Bellevue. Mike owns Chewelah Painting in Washington and has recently brought his log home finishing knowledge to Roe Paint in Idaho. Summer busyness is in full swing, so we’re grateful for the insights that Mike was willing to share about his business in the Pacific Northwest. 

How’d you get started in the log home finishing business? 

I am a carpenter by trade. I had every intention of working as a carpenter in Washington but was pulled into paint. We work in an area with a large number of log homes, and it wasn’t long before we worked on our first log home. The home came out great, but refinishing it was extremely tedious. Fortunately, I stumbled across Zero Failures and was blown away. Hands down the best training out there. I immediately bought a blaster and started marketing log home services. Three years later log homes became the majority of our work. 

How big is your crew now?  

We have five crews putting on coatings and working with several subcontractors.  Our sub-contractors are vetted and are a part of the team.  

What advice would you give to a newbie?  

Attend Zero Failures training and pay attention…then go back the next year and learn more. Pay attention in the classroom, but also pay attention to your work. You will learn something on every job and refine your process.  

What do you love most about log home refinishing? 

We are artists, but not in the traditional sense. We take a work of art and make it beautiful again. Each log blasts and stains differently depending on species, exposure, and a number of other factors. We learn something on every job. 

Mike, thanks for sharing a bit about your business. Feel free to look him up and pick his brain! 

If you are looking for some business tips to help you find the best clients, we have just what you need.

Let’s face it. All clients are not created equal. What’s good for your business goes beyond just bidding and winning jobs. The customer needs to be a good fit too. A critical skill in business is learning to go after customers and jobs that make your time and energy worth it. Learn to look for jobs that aren’t a drain, emotionally or financially. The truth is that there is more work than contractors right now. For you, that’s excellent news. And, these four top tips will help you find the best jobs and clients.

Will You Enjoy Working With Them

It’s okay to ask yourself if a potential client will be easy to work with and make the job enjoyable or if there are red flags that signal a nightmare scenario. If you suspect that you’re bidding on a job for demanding clients, it’s okay to walk away politely. Remember, find people who value the work you provide and are willing to work with you to get the job done. You have a helpful service to offer. Save your energy for the clients who value you.

Understand Who YOU Are Looking For

If you don’t know who your ideal target customer is, defining that is your top priority. How will you know when you find the best clients if you don’t know who you’re looking for? Take a moment to picture the perfect client and job. What’s it look like?

Ask yourself:

Having a clear strategy helps you reach your ideal client. You want to be a big fish in a small pond. Understanding your target market helps you get the potential customers you desire. Ultimately, building a business is about more than sales. Your goal should be to create something you enjoy and attract clients you want to work with.

Set Boundaries

Your clients want you to be in charge (even if they don’t know it). They hired you because they have confidence in your competence. It’s beneficial for you and them to set healthy boundaries for what’s acceptable and not while you work together.

Consider the Risk/Reward

It’s not uncommon for clients to look for contractors who offer ridiculously low prices. As a professional who provides products and services, that can be seriously frustrating. You provide good work and should be paid for the value you offer. The issue may be that you’re looking for business in the wrong places. Your goal should be to reach potential customers that understand your value. The internet is a blessing and a curse. Thanks to the old world-wide-web, everybody thinks they know everything, and they think they can get it done for pennies. This is not your ideal client. If a potential client’s first question is, «How much will it cost?» they are not your ideal client. Be picky about where you expend your time and expertise.

Rustic Park City feature

Can you tell us about your background? 

I started Rustic Park City in 2022 after working as the lead project manager for a prominent Park City general contractor for 6+ years. While working as a lead project manager, I learned rather quickly that my skills as a problem solver were well suited for this business. I also learned that I cared about meeting timeline commitments and budgets much more than most others in the business.  

How did you get started in log home finishing? 

I bought a log home in the mountains near Park City and decided to take the restoration job on myself. I quickly realized that despite being a general contractor, I had a lot to learn. A local distributor, Wasatch Timber, helped me learn each step of log home restoration and muster the courage to point a blaster at my own home. As I restored the home, I fell in love with the details: the depth of the wood grain, the way the sun highlights the curvature of each log, the living character, and the rustic feel. I am standing here looking at it now. Sashco products made the home stunning. Living in a log home high in the mountains is the dream.  

Our slogan at Rustic Park City is “Locals Building Locals.” We are protective of Park City, but we want others to have the opportunity to live the dream as well. 

What advice would you give to a newbie? 

Don’t devalue yourself. We don’t lower our prices. If at the end of a project you can walk away proud of your work, then the homeowner will be proud of it too. Work with dignity and integrity. You are an artisan.  

We are builders by trade, not business owners. To start a business, you have to go out there and face your fears. Do one thing each day that moves your business forward. Face one fear each day.  

What does the future look like for Rustic Park City? 

I am legitimately scared by how quickly we are growing. I have built a team around me to support our growth. I have hired multiple accountants, business managements, and legal counsel. Without the team around me I am nothing more than a guy with a truck.  

Michael, thanks for sharing a bit about your business. Feel free to look Michael up and pick his brain! 

DKS Log Home Restoration feature

Sashco is proud to feature Dynamic King Log Home Services as this month’s Contractor Who Cares.

How’d you get started in the log home finishing business? 

I fell in love with log homes when I was in fourth grade. I had always wanted to own a log home and bought one outside of Bozeman a few years ago. When the home needed work, I struggled to find a contractor.  

After this experience, I slowly transitioned DKS from general contracting to log home restoration and maintenance. We were working on log homes full-time by the end of 2021. 

What is the biggest challenge you have faced running DKS and how have you overcome it? 

The biggest challenge has been finding quality employees that mesh with our team. We have overcome this by including DKS employees in the interview process. We treat employees like family which is especially important when we travel for jobs. I worked in the oil fields for 17 years before starting DKS, which taught me a lot about team comradery. 

What do you love most about log home refinishing

I fell in love with log homes when I was in fourth grade. I enjoy preserving the natural beauty and history of our area’s log homes, while also ensuring their longevity for generations to come. 

What do you dislike most about log home refinishing? 

Sanding. Ensuring you have removed all the dead wood cells on a log can be very time-consuming. It’s an important process and a labor of love. We take the time to teach our employees the importance of proper prep. 

What’s the future hold for your business? 

We have grown substantially over the last year and are currently booked through 2023. We are planning to add a second crew soon. 

Donnie, thanks for sharing a bit about your business. Feel free to look Donnie up and pick his brain!
