How to choose high-quality sealant?

1. Look at environmental performance

As a product used for home decoration, sealant should first be green, environmentally friendly, non-toxic and harmless and not harmful to human health. Some inferior sealants have pungent odors and volatilize harmful substances, which can affect your health and even endanger your life.

2. Look at the product packaging

For regular brand sealants, the product name, factory name, specifications, place of origin, color, and date of manufacture will be marked on the packaging; the purpose, usage, precautions, etc. on the plastic bottle will be clearly stated; you should also pay attention to whether there is a certificate of compliance, product Inspection report, etc.

3. Look at the sealant quality

● Odor: The lighter the smell, the better the quality;

● Color: good surface gloss, no discoloration;

● Elasticity: The stronger the tensile force, the better the bonding force and the better the quality; for example, wood has stronger shrinkage than walls and ceramic tiles. If the glass sealant where it is connected to the wood products is not elastic, the wood products will expand due to thermal expansion and contraction. Glass sealant cracked.

Choose the right sealant, but not one type of sealant can "go all over the world"! When choosing home decoration sealants, you should make targeted choices based on different usage scenarios to achieve better sealing, bonding, aesthetics and other effects.

Doors and windows are exposed to wind and sun, and weather resistance cannot be ignored.

Doors and windows and other places need to withstand the test of wind and sun for a long time, which can easily lead to cracking, degumming, loosening of bonding joints, etc.

Therefore, the sealant used for bonding doors and windows needs to be better in terms of weather resistance and UV resistance.

The kitchen and bathroom space has a lot of moisture, so the anti-mold performance should be outstanding

Due to the high humidity in the kitchen and bathroom space, mold can easily breed, which is unhygienic and unsightly.

Therefore, the sealants used in kitchen and bathroom spaces have higher requirements for waterproofing, mildew resistance and other properties.

Neutral and acidic are clearly distinguished to prevent corrosion and pollution.

Acid sealant has a very strong bonding force and is generally used for bonding and sealing of sliding doors, dumb openings behind wooden lines, baseboards, and fish tank glass.

However, acidic sealant has a corrosive effect on metal, plastic, and concrete substrates. When sealing metal, plastic, concrete, and other substrates, neutral sealant must be used.

There are so many "sealants" in the field of home decoration. You must apply sealant according to the material. Have you learned it?
