DAP18742 Alex Flex PT Spackling, 16.0 Fl Oz, White

If you’re on the fence to buy this, just do it. Outstanding results thus far fixing those pesky drywall cracks in my older home. Applies and sands easy. Quick dry time. Keep in mind this does not fix any structural issues.

Used on an area with a reoccurring crack that I had previously fixed with regular spackle

I hope this will stop the dreaded cracks that keep coming back. Time will tell. It is easy to apply and sands out great. I hope it stays flexible enough to resist cracking.

Works exactly as advertised. Fills in those cracks smoothly.

Cosplayers that work with foam or flexible 3D printing filaments might want to check this product out. Not only does it fill gaps and print layer lines, but it’s actually flexible and sandable. It’s not as water resistant as Kwik Seal (it honestly reminds me of wood filler that’s just flexible) but there are other formulations you can try that contain silicone, such as Alex Plus and Alex Premium. But if this product is all you can find you can definitely give it a try!I tried this spackle to fill gaps on foaming TPU, which is a lot like EVA foam. I watered it down slightly for easy application. It sands just like wood filler, so make sure to wear PPE, keep away from children & pets and work safely! If you get it all over yourself or make a mistake you can wash it off by soaking it in water.

Don't be misled into thinking that this product will solve all of your cracks in drywall problems. The cracks returned less than three weeks after using it.Also, it dried up in the container REALLY fast.

We removed several tons of junk from an attic, and then the lath and plaster walls started in with more cracking due to the weight being removed. Regular sheet rock patch would be applied and small cracks would re-form. I recoated several times. After about 3 months of that, I moved to this product. Now there are no more cracks. I can attribute the lack of recurrent cracks to this product, or that the building simply was done reacting to the lost attic weight. One cannot say. Either way, I wish I started with this product first as it may have saved me some time.

The product was simple and easy to apply to the wall. Unfortunately this product claims to flex with fine cracks but after applying the product as directed, the crack reappeared in two weeks. The second attempt I left leaving it for a week before sanding and paint, the crack still reappeared within two weeks. Back to the drawing board and not with this product.
