Plus vs Sw950

Have been a fan of Sw 950 caulk for years, after using this product , I can highly recommend it for all your caulking needs. Good trigger and fast dry time.. Use it like a pro

It was okay

Last week I put the caulk to the test and used about 6 tubes. We caulked both large gaps and small around base boards, door jams, and window frames. Pros: This caulk is super easy to work with. Keeping a damp rag with you easily gets it off your hands and it has a long enough open time to tool without pulling. I was able to paint over it within an hour in some areas without a problem Cons: Shrinkage on larger gaps was more than I would have liked but I've used a lot worse. My biggest gripe is air bubbles in the tube. Whether or not you're using a dripless caulk gun this stuff will continue to leak, even with the gun disengaged. The reason for this is small pockets of air in the tube. When the plunger of the gun pushes the caulk it compresses the air pocket which will then causes the compressed air to continue pushing out the caulk even without pressure from the gun. Eventually you'll get past the air bubble, and can actually hear it pop as it comes out. Once past it the tube will no longer drip. Conclusion: For me the air bubbles are a deal breaker. It's a time killer constantly making sure I'm not leaking caulk all over the place. It's one thing is it's a fluke tube but this was the case in every tube I tried. For that reason alone I will not continue to use this caulk.

Alex Plus

I am a big fan of Alex Plus for quite a while. I tried some of the newer product and thought it worked great. It dries nice and smooth and ready to paint in 30 mins. Paint covers really well and creates a nice joint. Caulk holds up for a long time.

  1. Chris,
    You posted regarding DAP’s upgrade to their Caulks. I have recently found the new product mixed with the Old at H.D. however, the Label on the Alex Plus doesn’t say that it will not flash the paint. The Quick Dry does say Won’t shine through the paint. Just tried the Fast Dry Today and found the texture to be to My liking. The regular Alex I tried years ago was so thin that I didn’t like it at all. Maybe I got a bad batch. The fast dry seems to tool nicely. Now for the test to see if it shrinks or if it holds well.

    1. Hi Mike,
      Thanks for commenting, I’ll pass the information about the label on to DAP, look forward to hearing your final thoughts in the review section above.

      1. Hi Mike, I asked DAP about the labelling, their response, “ALEX PLUS is also formulated to reduce flashing, just like ALEX FAST DRY. DAP simply did not call it out on the label features/benefits to differentiate it from FAST DRY.”

        1. Way to go Chris!
          Good of You to follow up on that.
          It’s curious to Me that the Fast Dry has a 49 year label, and the Alex Plus has less. I would think it would be the other way around.
          The whole year thing is a made up gimmick anyway. What really counts is the ASTM rating.
