Bubbles your paint...
Its simple... this stuff is a disaster. I followed the instructions and waited a WEEK before painting, but this caulk out gasses for way longer than that and caused the paint to bubble. To add insult to injury, it's really hard if not impossible to remedy without replacing the siding. Use a silicone caulk and save yourself the time cost and headache of seeing your work ruined by an inferior product.

Thank you for sharing your feedback, and we are sorry to hear about your experience. Based on your description it sounds like the sealant wasn't fully cured at the time it was painted. OSI QUAD takes 7 - 14 days to fully cure and this time is dependent on temperature, humidity and depth of sealant applied. Once fully cured it can be painted with latex paint or primer. If you ever need help with our products, feel free to reach out to our technical team. OSI
    POORLY Labeled for Exterior use only. Paintable??
    The Home Depot rep pushed this product out of all the others when I asked for an interior gray calk. Labeling should prominently show that it is NOT for Interior use. And nowhere could I find anything about Paintability.

      Caulk and tube failed totally
      I bought this as recommended to bond glass and PVC lumber and the same advice said to avoid silicone for that purpose. While beading the caulk onto the PVC it failed to adhere at all and seemed to repel, and the seal at bottom of the tube totally failed and may have ruined my caulk gun. Cleanup of my window and gun was and is a nightmare. I went back to my original preference of GE Supreme Silicone and it does a fantastic job.

        Tube split and ruined caulk gun.
        Had a tube split and thought it was because it was old caulk. Bought two new tubes and started to apply in dry, 80 degree weather. First tube split the length and filled gun with sealant. Spent more time cleaning gun than job should have taken and still have to replace the caulk gun, rod bent and barely advances even at high speed setting. Where do I send the bill for reimbursement? Have applied hundreds of feet of different caulks without any problems until this caulk.

        We're so sorry you had this experience with our product. What you described isn't characteristic of OSI QUAD when the nozzle opening is cut large enough and the inner foil seal has been properly punctured. If you ever need assistance with our products, feel free to reach out to our team at 1-800-624-7767. OSI

          Good product but messy.
          After I had a 2nd tube burst/leak I decided to leave a review.

            I've had this in place for about 2 weeks. This was recommended by a high end window installer with the highest recommendations. I'd rather pay a little more and get better lifetime coverage, than to keep reapplying every few years. This is really tough stuff and awesome to apply. Does not shrink or peel, which is very important to say the least. Another good feature is that it has a self puncturing seal, so you don't have to insert a tool to puncture the seal initially. I'd recommend wearing vinyl gloves, once this dries on your hands it's very tough to get off.

            The sealant was very effective and flowed from the tube very evenly. I provided the coverage that I needed. I would chose this brand again for future projects.

            Very viscous consistency straight out of the tube. At first I thought I had purchased some old caulk but after reading other reviews I believe this product is just normally very stiff. I bought this for sealing under the mounting flanges of new windows but it is so stiff that it causes the flange to buckle between nails. Pushing on the flange helps the caulk to spread but I still ended up with a "wavy" flange. It probably would work great for applications where compression isn't necessary. It cures to a flexible, rubbery seal.

              Used this to seal around some stained wood. The color is definitely not brown but more grey. As a sealant it's great, but the color is not as advertised.

                Very good caulking
                Excellent product. Make sure you allow plenty of cure time before you want to paint, minimum required is 7 days. Use mineral spirits to clean up, the only thing that works.

                There isn’t really another way to get colour match caulking for Hardie/Allura etc that is cost effective. Just be aware this isn’t your bathroom-grade slippery caulking. It’s thick and sticky and if you are an amateur you’ll find it makes a mess if you need to tool it, so lay down some good lines.
