How to glue the toilet to the tiles and floor

It is best to caulk silicone sealants to secure the toilet to the floor. This is due to the fact that they are resistant to various environments: temperature extremes or high humidity. After hardening, the silicone forms superelastic seams that are not subject to deformation.

Important! Silicone sealants are great for all kinds of jobs.

Caulking toilet seat

Toilet seat sealant is a thick, pasty substance that is used both when installing new toilets and for repairing old ones.

When caulking around a toilet, the sealant is used as a waterproofing substrate around the toilet flange that prevents water from penetrating under the base, as well as as an additional means of gluing the toilet bowl to the floor. Especially if your toilet keeps running.

If leaks occur at the joints of the toilet bowl with the tiles, as well as when cracks appear on it, the silicone composition restores the tightness of the seams and the integrity of the bathroom.

Application of caulk when installing the toilet

Surface preparation for caulk application.

In order for the silicone caulk to show its properties as efficiently as possible and keep them as long as possible when installing the toilet, a number of rules must be followed.

The intended place of installation must be dry and clean.

For accurate distribution of the caulking flange, the base of the toilet is contoured on the floor. At the same time, experts recommend covering the surface around the contour with construction tape.

Holes for anchors drilled in the pre-marked places for installing and caulking the toilet are filled with a sealant (caulk) to prevent water from entering the flooring

Types of silicone sealants

Liquid silicone rubber is a substance used in construction work to protect against various effects of seams, cracks and joints.

Silicone sealants are sold in tubes and usually look like a thick gel. Resistant to temperature extremes or high humidity.

There are several types of sealants:

acetic or sour;

neutral;

sanitary.

Types of silicone sealants

Acetic or sour caulk

Acetic (acidic) sealants are one-component substances that contain: silicone rubber, enhancer, adhesion primer, silicone plasticizer and vulcanizer, and acetic acid. Such sealants have better adhesion and lower cost. However, they cannot be applied to materials that can react with acetic acid, as they will degrade (marble, aluminum, cement concrete, materials that react with acetic acid). Another disadvantage of these products is the sour smell.

Neutral caulk

Acidic and neutral sealants are similar in composition, differ only in the presence of acetic acid in the former. Like other building materials, they have certain advantages and disadvantages.

The benefits include:

resistance to temperature changes;

strength;

increased resistance to dampness, mold and mildew formation;

a large selection of color variations.

One of the drawbacks is the problem of discoloration of the colorless sealant. In addition, the product must not be applied to damp surfaces.

Important! Neutral sealants are suitable for a variety of materials.

Sanitary caulk

A separate group is highlighted sanitary sealants, which are ideal for the treatment of seams in living rooms. They differ from neutral and acetic ones in the presence of a fungicide that protects surfaces from the formation of fungus. These substances are suitable for processing a wide variety of materials.

The advantages of this type of product include:

– the presence of antifungal and antibacterial components;

– lack of vinegar additives;

– the ability to use on any materials;

– resistance to high humidity and temperature changes;

– increased strength and elasticity.

With many advantages, sanitary sealants have certain disadvantages:

– poor adhesion to polycarbonate, fluoroplastic and polyethylene;

– problems with staining;

– some products are not suitable for rooms with high humidity.

Silicone sealants to caulk toilet

Liquid silicone rubbers, commonly known as silicone sealants, are one-component or two-component substances designed to provide maximum protection for toilet flange, seams, cracks and joints.

Compared to other types of sealants, caulking around the toilet with silicone has a big number of advantages:

  • Resistance to moisture, heat, cold (from -50 to +200 ° С)
  • Good adhesion to various materials
  • Chemical resistance (cleaning agents)
  • Can be applied to surfaces of any temperature (cold or hot)
  • The presence of antifungal additives in the composition
  • Elasticity required for fixing moving parts
  • Smooth shiny surface after drying, formation of inconspicuous seams

Depending on the composition and the main active ingredients, silicone sealants are divided into acetic (acidic) and neutral. Separately, there are sanitary sealants that are ideal for sealing joints and waterproofing in bathrooms of residential premises, as well as for fixing moving parts in them. Check the flushing toilet and you will see if caulking the flange helps you.

Sanitary sealants have all the advantages of silicone compounds, but they do not contain dangerous additives and, when dried, have a very low shrinkage coefficient (2%), which guarantees the tightness of the created joints.

Which sealant is better to put the toilet on: flour of choice

Sealants are required not only to be used correctly, but also to be purchased.

When choosing a substance, pay attention:

On the date of manufacture. Often in the construction market there are expired products. You need to pay attention to this, because the building material, along with the expiration date, also loses its properties.

For Packaging. Damage to the integrity of the packaging leads to drying of the material and the impossibility of further use.

To the appointment. The packages indicate the purposes for which this or that material is used.

To the manufacturer. Renowned manufacturers guarantee the quality and reliability of their products. But not all well-known manufacturers overestimate the cost.

To the point of sale. It is not recommended to make purchases from questionable sellers at the flea market. It is better to go to a specialized store and consult a specialist.

Important! Spray sealants are becoming more and more popular. It is convenient to work with them, and when applying, you do not need to use additional tools. And it will be the best way of caulking the toilet. Also you should know that building a composting toilet you also should use silicon sealant on caulking the toilet flange – it is very necessary.

Is it possible to caulk a toilet flange without a sealant

When carrying out repair work in the bathroom, it is impossible to make a caulking toilet without a sealant. During the installation and caulking of the toilet, the sealant is used both as an independent building material and as an aid to the bolts to increase strength.
