Buying Guide The Best Silicone Caulk For Showers
The caulk is applied more in everyday life than many people think. They cannot distinguish the difference of each product for each case, so choose the wrong product and spend a lot of money but the result is not as expected.
Because understanding the difficulty of having so much information at so many different sources makes it difficult to find out, we have made a list of the necessary criteria when choosing the caulk.
- Mold & Mildew Resistance
The first thing I do is find out if the mildew resistant product is written on the package. This is very important because the caulk is often used in the bathroom or kitchen or sometimes outdoors, it will have to be exposed to water very often.
The texture, as well as the surface of the caulk, must be smooth so that the mold cannot adhere, it not only causes unsanitary conditions but also makes the area where you use the product.
Besides the purpose of filling gaps in the bathroom or kitchen, it can also be used to fill the mind in other places, but it will be less affected by water or moisture, so mold will slow down. than.
In short, if you have to fill your shower separators, make sure it is a mold resistant product.
- Waterproof
You must opt for the caulk that has this feature when you want to use it to seal leaky cracks. Most products on the market have this feature, but you still have to find out carefully that the product you choose is waterproof.
In case you do not pay attention to the water-resistance of the package or not and buy the wrong product, the caulk will easily get mold. This will take a lot of time to fill the crack as well as affect your finances.
- Elasticity
This is the third criterion that you should consider when choosing the caulk for moving places like shower doors or windows. If the product does not have good elasticity, it will break quickly or come off the surface.
If you are only using the caulk for fixed places like ceramic tile floors or bathroom walls, you probably don’t need this feature.
- Withstands Temperature Changes
This is one of the criteria you should consider when buying a product because the bathroom is where the temperature is changed frequently by hot and cold water tap systems.
Without this feature, the caulk will easily peel off the surface and you will have to replace the caulk regularly.
- Caulk Application
If you are a beginner and only use the caulk for a few small cracks or corners, you can choose the unused caulking gun for cost savings and ease of use.
But if you need to use the caulk for an area that is too large, you should have a caulking gun with a standard-sized caulk tube to save money.
- Colour Of The Caulk
Colour is one of the important factors to keep in mind when choosing the caulk. If you just fix a small crack or draw a serial line of the old caulk, the colour of the new caulk must match the colour of the old caulk so as not to lose the aesthetics of your house.
Most caulk will have two primary colours: white and clear, it will be suitable in most cases. However, if you need a caulk that is different from these two primary colours, you can choose a brand that has a variety of colours or you might consider buying a paintable caulk and a topcoat.
- Drying Time Of The Caulk
Both the bathroom and the kitchen chef are the areas you need to use every day so choosing the fast drying caulk is one of the criteria that should be prioritized.
If you choose a product that does not have fast drying criteria, you must be sure that you will not be using the bathroom or kitchen for at least 2 days for the caulk to get the best results.
- The price of silicone caulk for showers
The price of the caulk can be the key point in choosing your product. Choosing the right product for your affordability will need to be carefully considered.
The ingredients in the caulk for showers are very easy to manufacture and the cost for them is quite low so you should weigh the need and the price of the caulk.
How Much Caulk Is Enough?
Most people are confused with the amount of caulk they need to use for their problem. We have given a general formula in this article that can help you estimate the exact amount of caulk you should buy.
S (millimeter) / [D (millimeter) x W (millimeter)] = L (meter)
Where S is the size of the caulk tube, D is the depth of the caulk surface, W is the width of the caulk surface, L is the maximum length that you can use until the caulk is gone.
E.g
The capacity of caulk is 250 mm
The depth of the caulk surface is 8 mm
The width of the caulk surface is 6 mm
The result will be 250 / (8×6) = 5.21 linear meter which you can use with a caulk tube 250 mm in volume, and the depth and width of the caulk surface are 8 mm and 6 mm, respectively.
However, you should consider the discount of the product from 10% to 15% because you may use more than expected.
Caulk Type For Shower
There are many types of caulk available in the market however we will only mention 3 that are included in the products that we have mentioned in this few articles.
1. Acrylic Latex Caulk
This type of caulk can fill tiny gaps in any material. You will find professionals using it in furniture and wood building materials.
2. Vinyl Latex Caulk
This type of caulk has a scratch resistance so it is very suitable for long term projects. However, Vinyl’s elasticity is less than Acrylic, so it will easily crack when expanding and contracting.
3. Silicone Caulk
Most of the products on the market are not pure silicone, the reason given is that manufacturers have added some substances to increase durability, heat resistance, moisture resistance, etc.
Thanks to the plasticity and stickiness of silicone, it is not only waterproof, anti-mildew well, but also has a longer lifespan than other types of caulk.
