The best sealant for the bathroom

To protect the seams and joints between the tiles in the bathroom, various sealants are used. Also, they can close up the cracks between the net and the bath or sink, since it is there that water and steam constantly get. In humid and warm conditions, fungi, mold, harmful bacteria and pathogens develop well. To prevent their occurrence, fungicides, substances that inhibit mold growth, are included in the sealant for the bathroom.

Types of sealants

There are four types of sealants for the bathroom:

• Silicone is the most commonly used sealant, and the most expensive. It adheres well to any type of material. It can be used both for the bathroom and for sealing joints in tiles. It does not let water through and is indifferent to ultraviolet, can withstand significant temperature fluctuations and gives very little shrinkage. Silicone has a long service life.

The advantage of silicone sealant is that it can be applied even to a slightly damp surface.

Silicone sealants are acidic and neutral. The former have the smell of vinegar, are cheaper, but not for all metal bathtubs they can be used. Acidic sealants have the ability to oxidize metals, so they are best used for wood, plastic or ceramics.

• Acrylic - in terms of basic properties and service life is similar to silicone, but more profitable in price. It also does not fade in the sun, keeps in a wide range of temperatures. However, its seam has poor elasticity.

Plus acrylic sealant - it can be plastered, painted or varnished. It is used in various fields, so not all types are moisture resistant.

• Polyurethane - a good sealant, resistant to physical influences. Creates an even and plastic seam. Excellent adhesion to various materials. It can also be painted and varnished. When working, it emits harmful substances, therefore it is imperative to use protective equipment for the face and hands.

• Silicone-acrylic is a combination of two types of sealants. It has the greatest strength and durability. It is also used as glue.

Which sealant is better

For the bathroom, silicone sanitary sealant is best suited. It contains anti-mold fungicides. This type perfectly seals the joints between the wall and the bathroom, closes the seams, holes for the input of water pipes and sewers.

In addition to the active polymer, it may contain additives that improve its characteristics. As additives are used:

• Expanders;
• Fillers;
• Fungicides;
• Solvents;
• Dyes;
• Rubber;
• Mineral oils.

Care should be taken to ensure that the total amount of additives does not exceed 10%. If there are more, then such a sealant may turn out to be of poor quality and will not last long. It is better to refrain from buying it.
