Which caulk is best

Which caulk is best???


Is there any one caulk substance that is so much better than the others? I have wasted more than several hours trying to find info rather than post this here Now. I was going to use mapei sanded matching grout, but have seen some really bad caulk shrinkage... like a nightmare. (siliconized acrylic?) It seems like siliconized acrylic is the standard, but that it totally sucks, and 100% silicone is the way to go, at a mild sacrifice for color. There is sanded silicone, but it seems very limited? I will be caulking the corners and the tub line... (although I wish it all could be grouted.) Does Clear Silicone look good. (I am using a light grey shade of sanded grout with boost.) As a painter I rarely use any sanded grout but I wonder if the cracking/shrinkage you see is more of an application error rather than product failure. For painting a siliconized acrylic caulk is usually best but for caulking areas that tend to get wet you are usually better off with a full silicone caulk [not paintable] IMO a color matched [or close] caulk would look better than clear. You should caulk all changes of plane. That is your corners where 2 walls of tile meet. That being said if you grout the corner joints, the worst that will happen is they may develop a hairline crack. My recollection here is that you used wedi. If thats the case, and you used wedi's sealant, the worst that could happen is that the grout could get a hairline crack in it. Probably not even visible to the eye unless you really look close. The wedi board would prevent any water from making its way through to the framing so no problems really. As to the tile tub joint caulk it with 100% white silicone caulk. If you dont caulk this joint you will have problems guarnteed. Just finished the tile and clean up a little while ago. Unfortunately we have some grout lines that are 1/16. All the others are 1/8 and we are using sanded grout. Do you think I will be able to grout those few lines??? You will be able to get sanded grout into a 1/16 joint, not problem. I plan on grouting the whole niche. This is a plastic niche in a solid frame built with extra studs and long woodscrews. Hopefully this will be ok? Hi, For Caulking the tub and tile line; Please tell me if this is a good or bad idea? Hi, I have tried to make the caulk lines as small as possible in the past, and feel less is better to a point. If the bead is sealed against the wall-face side of the tile (left diagram,) then it would seem if any of the edge got loose, the water would try to go behind the bead, while if the top edge of the silicone bead was just below the tile against the small side edge(just like the grout,) then the water would be more likely to roll over the caulk... like shingles on a roof. I only have one chance to get it right; Is it better to try and caulk a shower like the example on the right? The red is, of course the surface of a caulk bead filling the gap between a tub and tile wall. (I have found silicone II product I like but it says concrete and masonry... any reason I should not use this tube vs. window and door? This one is almost the PERFECT color!) HI, Has anyone used or heard anything about Keracaulk S Caulk from Mapei? http://www.mapei.com/US-EN/product-d...62IDLinea=102 It was reccomended by a friend... well because it matches my grout... but that alone is not good enough reason... especially around a bath/shower. Almost finished. Need a screw for the shower handle and a curtain rod... and 24 hours for the Grout to dry. Used Color Rite's Sanded Caulk match for Mapei's Frost Grout #77. The colors were so so so close. Now, Curved, double, straight, curtain rod? Hmmmm. Next project 32X60 shower in the big bathroom and a backsplash for the kitchen. Will try to keep it all on one thread this time. A curved shower rod will give you so much more space and be much more comfortable to use! It most certainly did. Big difference. We picked up a moen dual curved shower curtain rod. Not to hard to install like the reviews said. Just use the templates and install with at least one helper.
