What To Consider Before Buying Caulk
There a lot of things out there related to the caulk and its application. And you know what! many people from around the world pick the wrong one and end up saying, the caulk is a crap.
So, in this buying guide, I’ll show the exact method what I use to pick the best one for my own use. Keep Reading…
1. Mold & Mildew Resistance
The primary feature I see in the packaging is that whether the caulk is mold resistant or not.
When a caulk is used in the shower or bathroom, it often comes in touch with the water. If the caulk is not smooth enough, the water will stick to the rough areas of the caulk and help the growth of mold. Mold makes the area unhygienic. It will also be uncomfortable for you when you see the dark spots at the edge of the tub or shower.
So, the caulk for shower or bathroom needs to be extremely protective against mold.
The other uses of caulk, such as exterior and decorative caulk, also demand this feature. But since those are not exposed to the water, the growth of mold on those will be much slower than the bathroom.
Next time you pick the best shower caulk, make sure it is mold and mildew resistant.
This is a must feature if you are planning to buy a caulk for sealing a leakage or filling any broken area.
Though most of the caulk out in the market come with this feature, you need to ensure the one you choose also is waterproof. If your caulk is not waterproof, mold will grow on it very fast and you’ll have to bear the burden of changing the caulk in quick time.
Now that we have discussed the first and most important two factors of caulk standard, the third in the row is the elasticity of the caulk.
The caulk must be elastic so that it doesn’t break when it is in moving situations. If you’re picking up the caulk for the floor or a wall which is permanent in its place, then you can skip these test (if you want). But when you intend to use that on the door, windows or in the exterior.
So you can now say that elasticity is the test for finding the best caulk for the exterior, door, and windows.
4. Heat & Cold Proof
This is a universal criterion for picking up the caulk. If you want the best caulk for shower, or the bathroom, or even for the exterior, you must see whether the caulk can survive both hot and cold weather.
If the caulk is not weatherproof, then it is very likely that you put the caulk today and see that the caulk is not sticking to the surface area on the next year.
How Much Caulk Do You Need
This is a common and an important question for the people new to the caulking arena. 9 out of 10 people fail to estimate the proper usage of caulk for a project.
After reading this, you’ll be one of those who estimate the correct amount of caulk for a particular project.
The formula is the “size of the tube in milliliter / (depth of the caulk surface in millimeter x width of the caulk surface in millimeter)”= The Number of linear meters you’ll be able to caulk with a tube.
If I give you an example, that will clear things like a mirror.
- The caulk tube is 250 ml
- The depth of the caulk surface is 8 mm
- the width of the caulk surface is 6 mm
So, the equation will be 250/(8×6)=5.21 linear meters can be caulked with a 250 ml tube with the width of 6 mm and depth of 8 mm.
N.B. You should consider 5% wastage when you make the decision of buying tubes of caulk.
Types Of Caulk and Their Uses
There are about a dozen types of caulk available in the market. Each type has some unique features and some drawbacks. I’ll discuss most popular of them in this subheading.
1. Acrylic Latex Caulk
This caulk has a nickname, the painters caulk. You can rightly guess now that this caulk can be painted which made this one the favorite caulk for the painters. This caulk is the perfect shot for repairing small holes in any place. This is generally used in the interior building materials, wood, and drywall.
This caulk can be painted right after putting it in the place which makes it the no #1 choice for the tool people.
2. Vinyl Latex Caulk
This is a similar type of caulk which we’ve discussed earlier. When the earlier one is easily washed away with soap and water, this can’t. Vinyl latex lasts longer than the acrylic and thus it is a pick for those who are building something permanent.
But as I said, every type have some drawbacks. It is not flexible like the acrylic one and thus can crack easily with expansion and contraction.
3. Silicone Caulk
Though you will suffer a lot of hassle finding a pure silicone caulk, most of the caulk manufacturer now use unique formulas of mixing up the ingredients. The silicone is extremely flexible and sticky which made this a raw material of caulk manufacturing. These are waterproof, mold and mildew resistant and have remarkably long lifespan compared to other caulk types.
