In the great caulk race of home improvement, two competitors have emerged as front runners: the silicone caulkers and the Dynaflex models. Dynaflex 230 & Dynaflex Ultra Vs. Silicone, who will be the winner?
Join me, dear reader, as we explore which product lives up to the hype and delivers the flexibility and durability one could only hope for from their caulk. Let’s get cracking!
Dynaflex 230 & Dynaflex Ultra Vs. Silicone: What’s the Difference?
Dynaflex 230 and Dynaflex Ultra are acrylic or latex-based sealants good for exterior use on common building materials. Gorilla 100% Silicone is a flexible pure silicone sealant suitable for exterior and interior use, with high-temperature resistance. Dynaflex Ultra offers enhanced weathering properties compared to Dynaflex 230. Gorilla Silicone offers a wider temperature range but doesn’t bond to some surfaces as Dynaflex does. But, For sealing a sink, I recommend using 100% silicone.

📝 My Hands-on Test of DYNAFLEX 230 Premium Elastomeric Silicone Sealant
I used this to seal cracks and drafts in my 130-year-old house that experiences significant movement. When I tried other brands, like Alex Fast Dry, it would crack in a day. But this caulk keeps my corners from having cracks and provides that extra security for corner cracks. I recommend taping, floating, texturing, and then caulking every corner before priming with PVA primer and painting. It really finishes the corners nicely.
BTW, This product is a little harder to work with than cheaper alternatives because it’s a touch stickier, but keep a wet rag nearby and back wipers you go. This stuff is awesome. It flows well and sticks, and it’s easy to wash off your fingers with water.
I found that this caulk is perfect for windows, doors, and floorboards. It’s just what I needed when I needed it and I’m pleased with it. The consistency is just right for working with and it sticks well.
The price is great and I like this brand because it usually works how I need it to. I bought a 6-pack for a large job and it was perfect. One year later, it has dried nicely and seems to be working well. I’m very happy with the way it has held up.
💬 FAQ of DYNAFLEX 230 Premium Elastomeric Silicone Sealant
Q: Is it possible to paint this caulk using regular primer+paint in one?
A: Yes, it’s possible to paint this caulk using regular primer+paint in one, but it’s important not to paint too soon. Always check the directions before proceeding.
Q: Does this product tend to attract dirt and is it easy to clean?
A: Over time, dirt can attach to this non-hardening product. We clean the exterior with water and the interior areas with a paintbrush and shop vac. However, it’s worth noting that our environment is very dusty.
Q: Can this be applied to something that’s wet or damp?
A: While it’s possible to apply this product to something that’s wet or damp, it’s best to ensure that the surface is clean and dry for optimal results.
Q: Is DYNAFLEX 230 caulking non-toxic and low fumes?
A: Yes, this latex-based caulking with silicone is low VOC and non-toxic.
Q: The photo of the DAP product shows brilliant white as the color, is it really brilliant white?
A: If the label indicates brilliant white, then that is the color that is in the tube. Brilliant white is simply caulking that will dry completely white.
Q: What is the shelf life of this product?
A: The shelf life of this product is 12 months.
Q: What pressure is required to get the caulk out of the tube? Is it 12:1?
A: This product is non-hardening and does not require specific pressure to be applied to get the caulk out of the tube.
Q: What is the recommended temperature for installation of this product outside?
A: I recommend a temperature of at least 50 degrees F for installation. It takes several hours to “skin dry,” so do not install outside if rain is expected within several hours.
Q: Can this be used to fix a crack in a water fountain?
A: While it’s doubtful that this product would be a lasting fix for a crack in a water fountain, Latacrete makes some products that might work better for this purpose.
Q: Do sealed tubes of this product expire? How can you tell when they expire if there’s no date on them?
A: Sealed tubes of this product do have an expiration date. The date is usually near the top of the tube, with the second pair of digits indicating the year and the final three indicating the day of that year. For example, “820123” indicates that the product expired on the 123rd day of 2020.
Q: Can this be used to seal a tub faucet or do I need a different silicone caulking?
A: This product is not silicone caulking, but rather an elastomeric that is paintable. Paint will not adhere to silicone, so it’s important to read the product specifications and compare them with silicone caulking to determine which one might work best for sealing a tub faucet.
Q: I was looking for DAP Dynaflex 230 10.1 oz. clay premium exterior/interior window, door, and trim sealant, but all that came up was white. What should I do?
A: You could check Ace Hardware, Home Depot, and Lowes for the specific color you’re looking for.
Q: Is it possible to use spray paint on this product?
A: It’s not recommended to use spray paint on this product as the solvent in the spray paint could attack and melt the caulk. Instead, use a polyurethane caulking sealant for spray painting.
Q: Should I apply this to raw wood or should I prime it first and then paint it?
A: Either way will work, but it’s recommended to paint first to ensure the best results.
📝 My Hands-on Test of Dynaflex Ultra
I was impressed by the claims of it being formulated with WeatherMax technology to resist UV fading, cracking, and dirt buildup.
When I opened the tube, I was happy to see the sealant had a smooth, easy-to-apply consistency. It squeezed out of the nozzle cleanly without too much effort. One thing I liked was that it applies white but then dries clear within about 7-14 days. This made it easy to see where I had applied it for nice, clean sealing lines.
The application was a breeze with Dynaflex Ultra. It smoothed on easily when I tooled it with my finger and didn’t drag or pull like some cheaper acrylic sealants I’ve used. It was also nice that it became tack free in about an hour, so I didn’t have to wait too long between application and painting.
It’s been about 6 months now since I applied Dynaflex Ultra around my windows and it is holding up great. Through rain, snow, and UV exposure, the sealant remains intact and has not cracked or peeled at all. The manufacturer’s claims of UV and weather resistance seem to be valid in my experience. I also haven’t noticed any dirty streaks or mildew forming as I have with other sealants.

📝 My Hands-on Test of Gorilla Waterproof Caulk & Seal 100% Silicone
Gorilla Silicone is nothing short of amazing. It applies like liquid glass, and I have never seen caulking apply so smoothly. There were no air bubbles whatsoever, and it makes a rookie like myself look great. The cleanup process was also easy, and it is a clear winner for me. I will never go back to acrylinized silicone or other paintable ones. Mold cannot grow on pure silicone, and the more pure silicone you use, the longer it stays clear.
The bond this Gorilla Silicone makes is incredibly strong, and it makes no less of a bond even underwater. This is a new technology by Gorilla, and Amazon has the best price. It is more expensive than other silicones, but in terms of durability and the final result, I feel that it is better than many others. The drying process is fast, and the smell, albeit pungent at first, dissipates quickly. It did what it claimed, and it doesn’t get any better than that.
The product is of excellent quality, and it performs as advertised. The Gorilla caulk comes with a cap to reseal the unused portion, and it is fairly priced, making it a win-win for all caulking jobs. Like most silicone tubes, once you are done, you can close the end with the cut rubber glove finger trick. However, I noticed that the tube end was super clogged when I went to use it two days later. I tried tapping the end and side of the tube near the end seal, but it did not work. I had to throw that tube away, almost three-quarters full.
💬 FAQ of Gorilla Waterproof Caulk & Seal 100% Silicone
Q: Is a caulking gun necessary to apply this product?
A: Yes, a caulking gun is required to apply any brand of caulk that comes in a 10 oz round tube, including this one. It is recommended that every handyperson should have one, and cheaper ones work just as well as expensive ones. Some people who write bad reviews may not realize that all brands of caulk in these tubes come with a sealing membrane inside the nozzle. The caulking gun comes with a rod that is about the size of a nail, which can be used to break the membrane by folding it out and sticking it down the nozzle a few times, or by using a screwdriver or another tool of your choice.
Q: Can I use this product to reattach loose outdoor ceramic tiles caused by worn grout?
A: Gorilla Clear 100% Silicone Sealant is effective for sealing around tile surfaces. To reattach the tile, it is recommended to use Gorilla Heavy Duty Construction Adhesive.

A: Gorilla Clear 100% Silicone Sealant is not paintable.

A: A 10oz tube of Gorilla Clear 100% Silicone Sealant can cover 52 linear feet (17.3yd) using a 3/16 inch (4.76mm) bead. This is approximately enough to caulk two bathtubs and one sink or three standard doors and four windows.
Q: Once opened, how many days or months can I keep the same bottle of this product?
A: The best way to store Gorilla Clear 100% Silicone Sealant in a cartridge is in a cool, dry location away from heat with the nozzle attached. To re-use the product, remove the nozzle and cured sealant from the tip, and store it away from children and animals.
