Customer Reviews for DAP Dynaflex 230 10.1 oz. White Premium Exterior/Interior Window, Door and Trim Sealant (6-Pack)

Very good caulk! Easy to apply and because it has so much elasticity, it seals really reliably. I ahd previously used a stiffer caulk for a bathroom vanity and it cracked. This one doesn’t crack even if you budge and wiggle the vanity.

I needed ext caulk for siding (almond color) that was installed 2015. I tried the Almond color of DAP. It was a perfect match.

I live in NE Florida. As I write this, it is Jan 2024. I bought my new to me house in 2006. During the first couple months of home ownership, I tried to right all the wrongs left for me by the previous owner. My home has wood flooring, and there were gaps or spaces that looked unsightly. I found this brown Dynaflex 230 premium, the color almost matched the floor, and it seemed a easy solution. I filled the gaps, and sealed the tube for storage. I always put 2 pieces electrical tape over the tip, then wrap the nozzle round and round for a air tight seal. I keep my unused caulks in my hot humid garage. Today I needed some caulk for a project, color didn't matter, so I thought I'd see what I might have. I pulled this tube from a high shelf and began to unseal it. The tip material was dried and wouldn't budge so I cut some off the nozzle. After some effort, the cured material started to move and very soon pliable caulk began to flow. Wow, I couldn't believe it! It applied like it was bought recently, not 18 years ago. I am sold!!

I like using this for base and trim and windows. Easy to work with and gives a nice finish when done. Seams to last and stay flexible. It set ups rather well compared to other's I have used and can be painted in the same day when you time it right. Definitely a go to for a lot of my projects.

As a quality control professional, I'd be mortified to see this. I bought a tube of clear caulk and it was actually white, as shown in the attached photo. Of course, I will return but that doesn't do much for my wasted time.

I bought Almond DAP caulk to fill in around door frame molding after new vinyl plank flooring was installed. The color shown on the packaging matched really well. That color on the packaging is not remotely close to the reality of the product which is slightly warm and off-white.

Worked well, I painted over it and so far no mold.

The color when wet was perfect and I was very happy with how it went on. But once it dried I was very disappointed. It's much more yellow than almond as you can see in the photo. Now after spending a couple hours getting all the old nasty grungy caulk off and completely cleaned it looks like I haven't done anything. Complete waist of time and money.

It’s great caulk, but 1/4 of each tube is wasted because it continues to flow, even with a drip less caulk gun. Caulking exterior, 30’ up on a ladder, this becomes very messy and inefficient.

Fills large gaps. Dries timely. Buy more than you think you need, their may not any on the shelf when you return.

I got this because I like dap products and needed it to fill in gaps against molding. 1 container did a 13x13 room, closet included, and just shy of roughly 18" before I had to open a second one. It went on smooth with barely any air bubbles and dried fast. The white goes well with the high gloss I painted the trim. It filled gaps up to a quarter inch no problem and there's hardly any smell. Nice and easy clean up too. It smooths real easily whether with your finger or a damp paper towel.

I was looking for a medium brown caulk to match my trim. Apply this next to a true medium brown color and you can see that it is more of a purplish hue than a true brown. Not even an attractive color or purplish brown. Better experiment first before committing to this color.

This is really good caulk. Used it to seal exterior joint where mortar meets trim.

This caulking worked well to fill spaces between boards on a patio cover. Some spaces were up to 1/2 inch wide. I allowed it several days to cure and re-caulked any low spots. Again waited for it to cure and painted it. I would not hesitate to use this product for future projects.

Behaves like a blend of silicone and butyl rubber when cured. Lots of stretch, doesn't crack, and hasnt yellowed in the sun by my sliding door. It's even replacing the butyl rubber material in my RV corner seals. Might not be 100% waterproof like polyurethane or silicone, but I think the bond quality and flexibility coupled with the 5cm (!!) gap rating makes up for any worries you might have. Plus, the best part is you can clean it up with just a bit of water, or even with a dry rag!

I have been using Dap products for years and all you need to do is think of what you are using this product for and select the right product. Be sure to follow prep and drying time of this product before you paint or stain and check weather conditions.

I bought this in clear mistakenly. I've gone through probably 20 tubes of white. When I looked on the label to see the time until you can paint over it, it says 7-14 days! I checked the white tube and it says 2-4 hours, 7-14 days to full cure. I'm assuming this is a typo based on a previous customer review that I searched out that said 7-14 days until paint is nuts and gave it a low rating. The response from a rep was that 2-4 hours AS THE LABEL STATES is the time until it will accept paint. Most likely the rep doesn't have a misprinted label like I got, and most likely the reviewer had. Good stuff, doesn't go on as easily and isn't as easy to work with as the white stuff, but still way better than acrylic latex painters caulk (cheap stuff). Hopefully this review helps someone.

After installing white crown, chair rail, and baseboard molding in our old house, the unevenness of the walls became very obvious. Dynaflex 230 to the rescue! With a little practice and the tip cut at an angle, you can put in a bead of caulk into the gap without too much cleanup required. For the photo, I stopped a couple feet short of the wall. The top edges were already done. It makes for a MUCH cleaner appearance. Three weeks and multiple daily showers later - no cracking or shrinking or anything. I have done the same with trim installed in other rooms with similar high quality results. This approach also makes it a lot easier to paint adjacent to the trim by cutting in with a brush.

I had an old stock tank I wanted to turn into a water container garden, but it had some small leaks around the base. I used this sealant on the inside of the tank and the outside around the seams, and let it dry for about a week. Then I got impatient and filled it with water anyway (it said it could take a couple of weeks to dry completely). When I filled it up the leaks were much better, and it could hold water almost completely, but still leaked a little bit. I figured it wasn't that big of a deal and I would need to do periodic water changes anyway, so I left it at that. The biggest surprise came like a week later when this stuff finished drying (while holding water) and now it doesn't leak at all! THIS STUFF IS MAGIC!

I recently stripped and scraped 50 years worth of old white caulk from the wood trim around my front door where the trim abuts to brick. After removing the old caulk, the contrast between the brick and dark newly-painted trim looked really good - but there was an air gap. Filling with white caulk would not have looked good, so I tried the clear variety of this product. The result was very satisfying. The photos show the result and what the trim to brick transition looked like "before". Note that the clear caulk goes on white, but after several days it turns clear as it cures. Don't forget to fill wider gaps with foam backer as the instructions suggest.

I have used this on a number of different projects. I just got more of this today, I used it this time to glue camouflage on a toy tank.

I have used this product before. It works well and seals perfectly. Whenever, I install windows, Dynaflex 230 is my first purchase.

100% Water proof unless you get it wet. DAP = "Don't Apply Period" It NEVER cured and now it's all over a brand new $25,000 deck. Calling them was no help. All I can do now is scrape and scrub and hope I don't destroy the deck or the house. This stuff is JUNK!

Very easy to work with. Easy clean up.

Great product

Works great and paint goes on easily. A nice way to give a finished look to nearly any project.

When you're buying caulk, you should be aware that, just like paint, the price is going to indicate the quality. In the caulk family, the cheapest caulk is PAINTER'S CAULK. Painter's caulk (called Dap brand Alex Painters Caulk at Home Depot) is low quality and will crack and fail within a short period of time. Painters will use painters caulk to save money. DON'T LET THEM. The next price point up is PAINTER'S CAULK WITH SILICONE (The main brand that Home Depot sells is called Dap Alex Plus). This is a better choice than plain painters caulk because it is made from acrylic, a more flexible glue that is the primary ingredient. They also add a very SMALL amount of silicone to further prevent cracking. While this is a good choice, but you can still do better. Read on. The next price point up is ELASTOMERIC CAULK. (The main brand Home Depot sells is called Dap Dynaflex 230). Elastomeric caulk is far superior than the previous 2 mentioned. It is flexible up to 50% of it's size and can be painted. It lasts YEARS. Home Depot sells it in a wide variety of colors. When I have contractors doing work on my house for me, I ALWAYS insist that they use Dynaflex 230 Elastomeric Caulk. It may cost $1-$2 more, but it is WORTH IT. In the 2 pictures I submitted, this is a large piece of Dynaflex 230 that was removed from a patio door that was changed out. It was on there for about 2 months. In the first picture noticed how much it will stretch without breaking. I could have stretched it even further (like gum, but stronger), but it was too difficult to stretch it and hold my camera and push the button at the same time! In the second picture, I have twisted it to show the flexibility. The twist is to the left of the piece. Take note that other retailers sell this product also, so it is widely available.

This is a great caulk I actually used it around my laminate stair treads I just did, however I wish they had a darker gray too. it worked nicer than a bright white. the 1st coat sank a little and had to go back and do a 2nd coat as well. No big deal. I would recommend and will buy again. I like dap products.

Sealed and ready in an hour. Every year we reseal our basin sink. We wash everything in that sink, even the dog. First I used painters blue masking tape, it saves a bit of work on smoothing the sealant. I will run my fingernail or a non-sharp edge between the tape and the seal and the blue tape comes off without pulling the silicone. We wash big hot soup pots, so we like the seal to be good and fresh. Even with going hot to cold, it does not crack or peal. The clean-up is easy. It does not smell. It works with varied materials, like the porceline sink to the granite top. I always keep a tube of this around the house.

We tried the painters sealant ALEX also by DAP. This sealant did not crack or shrink like the ALEX product did. This sealant is worth the extra cost.
