Best way to install vanity backsplash. #diy #youtubeshorts #diyshorts

1. Better to put a few blobs of silicone on back of backsplash instead of continuous bead, that way it’s easier to remove down the road for whatever reason justifies the occasion.

2. Backsplash needs to have a bead of silicone applied to the bottom front edge, to seal and prevent water from going between the 2 surfaces, where sitting water will dehydrate and cause long term mineral buildup. If you want it to look nice, apply painters tape first on both sides of where you plan to put the bead, make sure the gap between the two rows of painters tape is 1/6” (that way the result will not be a fat bead). Apply silicone, use finger to smooth bead, which also acts to ensure proper adhesion to the surfaces on both sides. Remove painters tape. The result is a waterproof edge that looks amazing. Must use neutral cure silicone in areas that are against porous materials such as natural stone, OR a reactive material such copper or other reactive metals. This is IMPORTANT. Note: if you use acetoxy silicone (vinegar smelling silicone) on any porous material or material reactive to acidity, the result will be regret due to break down of material, bleeding of color, and potentially failed bond. Acetoxy silicone has it’s purposes, as it’s cheaper and dries faster, but you must make sure to have the adherence range dialed. Both have their place. Look it up more in depth if you don’t understand the two different types and their adherence ranges, it’ll save you $$$.

3. Topside of backsplash needs a bead of paintable caulk, or else water can splash behind the baskspash and cause water damage.

Many people forget to tell people about "marrying aka bonding" the two materials by scooting them each direction a little bit. I consider it essential.

Instead of the snakey snake put a continuous bead near the top edge so water doesn't get trapped between the splash back and wall, in addition a line of sealant should be applied to the top edge of that splash back later.

Better to do 3-4 thicker blobs of silicon incase the wall is out but also it allows you to remove it down the road. Don’t forget to caulk the top gap and sides as well.

To each is own but when I do this I use circles in which they create sort of a suction cup and I use PL 3 as well then I silicone the bottom wipe off with denatured alcohol and color match the caulk on top and the sides

But wouldn’t you be left with a slight gap under the backsplash? Even if water can’t go behind the vanity it will still sit under the backsplash eventually turning into mold

So this is the reason tear outs are so hard to do. This is a little over board, three or four dollops on the back are fine. Also a thin bead on the front at the bottom will waterproof all you need. Easier tear out down the road and just as secure, also less silicone used. Thanks for doing the videos, just thought i would share

[steve_main]

if it does not squeeze out the front there will be grime and dirt that you can never clean out in that tiny little crack between counter and the backsplash.

Here’s a novel idea… do it b4 you install the faucet so you can rake and strike your sealant properly and don’t be a pansy and put your hardware in after. It’s done correctly and the Best way for the customer!
U know what it looks like 3 months down the road wen all the grime is collected under the edge of the splash later!

Why would anyone wait until the faucet is installed to put the backsplash on? Its usually installed when the vanity top is installed ...

[macmckulis]

My grandma told me to use only 3 dime side beads on the back of the backsplash. It is important for the removal, if any issues to be found.

[ajcressey]

Do circles on the back get you more suction

[deannagreenberg]

Great idea, and wonderful grandson to not forget to give credit to your grandma!😊

[ndMorrow]

Yo, why's your grandma so good with caulk?

[papawhelp]

Did you fill the bottom crack, I didn't see where you wiped it smooth...

[zxSkeeter]

Great tip and if you use hot glue dots it will be held immediately until silicone cures.

[vancegentry]

like the chaulk on the bottom but would have used a better adhesive on the back so it sticks to wall better

[captkerk]

Great video. Short, sweet and effective. Need more like this.

[Apexjasonmorganllc]

Do that before fixtures so you can actually caulk it. Also you should put some pressure on that and move it side to side to adhere properly.

Do you caulk the location the vanity meets the backsplash?
