First, how much caulk to buy? One tube would last me 1-3 average rooms (of re-painting). We only discuss the 10-11 oz. size tubes here: none of the quart size “large” tubes you see in the photo above.
For a very straight line between two colors, such as the ceiling and wall, we lay a bead of caulk in the corner. We caulk all trim/wall joints needless to say.
You cannot store unopened tubes for years: see our other post all about caulk and on how to do the caulking, how to buy the right caulk gun and how to load a caulk gun.
Painting or sealing tub/sink/shower?
(Below there is more such as masonry, butyl, etc)
Note that caulks with silicone, even paint-able ones, take longer to dry than non-silicone. Check the specs before using outdoors: many of the best caulks are suitable for both interior and exterior.
The #1, go-to product I have used all my life is here at a very good price: the painter’s indoor/outdoor caulk from DAP .
My 2nd favorite is Alex Plus: it’s the same as the one above but has a longer life and more flexibility, (because it has some silicone, which therefore takes longer to dry): it comes in Clear - Almond - Black - Brown - Tan - Bronze - Gray
Just painting a small room or a few cracks? Hand squeeze tubes are the way to go:DAP 3 pack, White DAP Almond, 1 tube Outdoor white
2. SHOWER, TUB, SINK
If it gets wet, go the full monty: silicone caulk (our pick can be painted, but does not have to be painted). Even the best caulk made of silicon is toxic: read the warning section at the bottom!
Use the best silicone product today: paintable Gorrilla (company website). This is the very best caulk for silicone caulking applications on the market. It comes ina caulk gun tube or in hand-squeeze tubes.
How much to buy? One hand squeeze tube will do a tub if your cracks are small. Don’t use to replace grout.
Have a big tub or shower? You’ll need a full tube or several hand-squeeze tubes.
3. MASONRY , METAL, AND OTHER CAULKS
Sidewalk cracks? Save your mothers’ backs with concrete caulk: a case is a very good deal. It keeps water out of your pavement to extend lifespan.
Grout? Comes in 3 colors: beige, gray and redwood.
Butyl Rubber caulk is suitable for always-wet applications – just read about how to get good bonding.
Custom color: match any color I’ve never tried it. Let me know if it works out? Thanks
4. Glue comes in a tube: ba-da-boom. Genius.
I use these two: Gorrilla Construction Adhesive, yeah baby. (this is not the expanding when wet type)…and…
Dap Construction adhesive comes in a tube and is the best deal in glue.
Summary: When I was young my first employer taught me about the best caulk. If you have any questions about how to use a caulking gun or anything else, let us know in the comments.
Silicone caulk warnings:
- You only need silicone where you splash water: most are very toxic and difficult (messy) to use, and where you have porous surfaces (it does not bond well). Use gloves, please wear a respirator: very important – the best respirator is linked in Part 7, below) and open windows.
- Some people use painter's tape to keep the bead of caulk small: that is good if you are new at this.
- You usually do need to use silicone for glass, tile etc, but you should know that it is quite hard to remove after it cures.
- Let fresh silicone caulk dry overnight, 24 hours before using the shower cured and 100 percent waterproof. Even fast-drying products should be given 6-12 hours to cure before using the shower.
- Silicone caulk is very sticky and cannot be washed up with water. Use rubbing alcohol* to clean up before it dries. Full rubber gloves are a good idea as it sticks to hands like glue. *Read label: some types use paint thinner/mineral spirits to clean up.
- Open windows and doors near the caulk you wish to cure faster and keep the area warm. You can set up fans and/or dehumidifiers too.
- There is more under Section #1: “How to use caulk gun”. Look for How to use a caulking gun in a shower?
5. Bonus: doing the job with no gun
If you are just doing this once and you don’t want to buy even the lowest priced caulk gun out there: yes, you can get by. You can buy caulks in a toothpaste type tube (silicone kitchen and bath and of course painter's acrylic caulk. So you really do not need to know how to use a caulking gun.
These small tubes are a bit more expensive for what you get, but it is a good thing to have around. There is a construction grade glue as well.
Please see my video below for what to do if your nozzle becomes clogged beyond saving: you don’t have to trash it!
Ok fun time.
How to use caulk gun you make yourself (and this is in the video below). Use a T-shaped stick (such as the handle of a hammer): Put the stick into the back of the tube and just push the caulk out by pulling the tube back into your shoulder or chest! That’s how to use a caulking gun with no caulking gun!
