Really good quality and easy to apply.
Top quality.Caulk. This easily fitted in my standard gun and was so easy to apply. Smooth with a damp finger and dried quickly. Looks fantastic and would definitely buy this product again.

Leaky but good
Amazing quality caulk, easy to use. Doesn’t dry as fast as id expected but for the price cannot complain. I will say if you have an average caulk gun caulk tends to seep out the bottom part presumably because the bottle isn’t sealed properly to the sides when its pushed? Overall good quality

Good Caulk, But Check Before You Buy!
The Everbuild Caulk Once does exactly what it’s supposed to, smooth application, dries well, and leaves a clean finish. It’s a good quality acrylic caulk that works great for sealing gaps and cracks around skirting boards, door frames, and similar surfaces. That being said… make sure it’s the right product for your needs before buying. I picked this up thinking it would work for my project, but turns out it wasn’t the right thing for the job. That’s on me, not the product, but still, it’s worth double-checking to avoid an unnecessary DIY fail! ✅ Easy to apply and smooths out well ✅ Dries quickly with a nice finish ✅ Good for sealing gaps around woodwork and walls ⚠️ Not suitable for everything, check before you buy! Overall, a solid caulk that does what it should, just make sure it's the right one for your task before you end up staring at it wondering where you went wrong!

Good product, recommended and will buy again.
Really happy with this item, it was my first time using a product like this but it was easy to use and gave a lovely finish. It was very functional for what I wanted and was quite sticky.

Does the job
Does what it’s supposed to but feel you will need a decent gun to use it as it’s a lot more dense than normal mastic

Good caulk
Really good caulk. It’s super flexible once dry and really easy to tool with a bit of soapy water. It says paintable after an hour but after the hour it felt like it was ok to paint, but soons I started to paint it the caulk started to get mixed throughout the paint causing it to drag anywhere I painted. Apart from that it is a good quality caulk and well worth the price. I would maybe just wait a couple of hours before painting.
