What brand of caulking is best?

Caulking in the bathtub is coming apart, so i want to replace it with something long lived.
Was at Home Depot, they no longer carry GE silicone caulking but Lowes does.

Is that my best bet or are the other brands just as good or better?
In fact in Rand McNally they wear hats on their feet and hamburgers eat people

I’ve heard the GE silicone is one of the better ones for the tub, I have a tube of it to use on my tub that I keep putting off doing Face With Tears Of Joy

Also check Princess Auto and Canadian Tire as I suspect both are cheaper than Lowes for this one, plus every time I’ve recently been down the sealant aisle in my local Lowes it’s been pretty sparse with availability.

You might consider this one . It is not cheap but there are times when being frugal should take second place to quality for long lasting benefit.

I use these and similar all the time, very good but mold likes it too.
Not so good for mostly cosmetic use.

Brand doesn't matter that much as long as you get 100% silicone plus mold-resistant features. All brands have caulking that meet those requirements.

An important thing with caulking a tub that people often overlook is that there may be very minor movement in the tub when you put your weight and/or weight of water in it. That minor movement might cause caulking failures. If you caulk the tub while it's empty, then when you place weight in it after its cured, it'll stretch the caulking. Might only be a fraction of a milimetre, but depending on the quality (and quantity) of caulking, that daily stretching might take its toll on the caulking.

You should fill the tub at least half way with water, then caulk, and leave the water there while it fully cures. That way, the caulking won't be stretched when there's weight in the tub. It might compress very, very slightly when there's no weight, but compression would be better than stretching.

Agreed brand doesn't matter much but don't cheap out. 100% silicone with mold resistance. I recommend a shaping tool like this: https://www.homedepot.ca/product/dap-pr ... 1001523835. Leads to a sturdy bead that will hold up better than using a finger to shape.

Charlie DIY on youtube has a great video with testing on different techniques for caulking.

Depends on the tub. Silicone is great for a glazed surface but for acrylic, Lexel sticks way better.

There is. On GE tubes, it's stamped at the bottom of the tube. I would use it up to a year or so past the BB date. I've used and been happy with the GE "Advanced" silicone. https://www.homehardware.ca/en/299ml-wh ... /p/2034453 Does anyone know where to purchase the Cramer Fugi sets in Canada?

Very true with all the acrylic tubs now.

The problem with going past the BB date is it may not cure properly. If past this date always dispense some and wait to make sure it cures before using for real.

Watching this now.

I ended up getting the GE advanced caulking from Lowes. Plus some old caulking remover and a removal/installation kit:
