Choose Waterproof, Mildew And Crack Sealant To Pay Attention To The Problem

  When finishing the edges of the whole house, it is best to choose waterproof, mildew-proof, and crack-resistant sealant for edge sealing. If we fail to select a truly effective sealant that is both waterproof and mildew-resistant, then in relatively humid areas such as the kitchen and bathroom, mildew stains will appear in no time. Studies have shown that bathrooms are basically heavily polluted with mold. Globally, 70% of households have reached heavy pollution levels in Xu Jun's tests, and 56% of households have been found to be heavily polluted in mold tests. Families with pregnant women must pay particular attention! The harm caused by mold is not negligible, and we must take it seriously.

To help you avoid mistakes when choosing sealant for edge sealing in your entire home, I will today share with you some common knowledge on how to select the right sealant.

Common Knowledge for Choosing Sealant

  Firstly, the most important factor when selecting sealant is the brand. Always choose brands with high reputation, as the quality of big brands is more reliable, their promotional content matches the actual product, and you can use them with greater peace of mind. Some small brands may advertise their products as mildew-resistant, but in reality, mildew will appear soon, making the promotional content completely inconsistent with the actual effect. This will result in wasted effort and money, and you may still need to redo the work. In addition to focusing on the brand, it is also necessary to understand how to select specific parameters, such as the scope of application. Many sealants are only suitable for use in dry areas and cannot withstand the sealing requirements of wet or damp areas. For ordinary consumers like us, it is better to directly choose a sealant that can cover both dry and wet areas. The three characteristics of waterproof, mildew-proof, and crack-resistant are also crucial for sealant. Some brands may avoid mentioning the hard defects of their products and only talk about waterproofness or mildew resistance. When making a selection, ensure that you choose a versatile sealant that can guarantee the effectiveness of your edge sealing. Lastly, environmental protection is a concern for many during home renovation, including the selection of sealant. Choose an environmentally friendly and odorless sealant to minimize indoor formaldehyde during decoration.

How to Use

1. Before applying the sealant, thoroughly clean the area to be sealed to ensure that the sealant adheres to the surface, not dirt or debris. If the area is not cleaned properly, the sealing effect will be significantly reduced, so be sure to clean thoroughly.

2. Apply masking tape to both sides of the sealing area to prevent the excess sealant from sticking to other areas.

3. Load the sealant cartridge into the caulking gun and adjust the nozzle according to the size of the gap. The nozzle size should match the gap perfectly, neither too large nor too small, to ensure that the sealant fully covers the gap in one pass. A helpful tip is to flatten the nozzle first and then cut it diagonally. This will create a flat elliptical bead of sealant, reducing the need for a pressing tool and making the application easier overall.
