Choosing the best toilet sealant Toilet Sealant - Installation, Varieties and Applications

In the toilet and bathroom, where the level of humidity is constantly increasing, fungal colonies and mold often appear on the floor surface. To reduce the risk of such the latter, you should use a bath and toilet sealant. A tool such as a toilet sealant reliably seals all holes and joints, protects the floor from leaks and the formation of pathogenic microscopic organisms.

Depending on the properties and composition, all sealants can be divided into several types, although there are gels and combined pastes.


Usually, such products are marked with or without water resistance. If the adhesive sealant is not distinguished by the ability to resist moisture, it can only be used in dry rooms. Waterproof acrylic sealants are able to withstand high humidity, but they usually cannot tolerate constant contact with water. The advantages of the compositions include safety for human health, excellent adhesion, a large selection of shades. It is recommended to use them for repair work on pieces of furniture, doors, windows, but cannot be used in the bathroom.

Types of sealant


These are the best products for tiles, toilets, bathtubs, sinks, various surfaces in the kitchen, and they are in great demand among different craftsmen. Silicone types of pastes have the highest resistance to moisture, temperature extremes, they can be used for indoor and outdoor work.


They can be adhesive elastic compounds with polyurethane, which is characterized by durability, strength and resistance to wear (on its base make many types of liquid nails). Such compositions are suitable for installing and strengthening the toilet cistern, as well as sealing at the base. But such compositions have a huge drawback - toxicity, and therefore are often recommended for outdoor work.


Such sealants are mainly used for outdoor work. They are perfect for installation and renovation work for roofing materials, fastening shingles, sealing brick masonry, gutters, foundations, chimneys and ventilation. Bituminous agents do not react to the action of ultraviolet rays, they fill even huge voids, but they also contain solvents, and therefore they are very toxic.


Silicone-type sealant features

Choosing the best toilet sealant To glue the toilet to the floor, seal its base, you should buy a silicone-type compound. This is a one-component, one-pack type, which most reliably closes cracks, seams, pits and defects.

silicone sealants can be divided into several types.

Sour or acetic

Such products can be classified as "economy" sealants - they are affordable, fairly cheap and reliable. Of the shortcomings, we single out a sour aroma, which indicates the presence of acid in the composition, and therefore sealants cannot be used on the surface of aluminum or marble due to the risk of damage.


To glue the toilet with a sealant, you should use a product. Such compositions are based on alcohol components, as well as metal oxides, which make them much stronger.

They are suitable for all types of materials, do not damage them, but they are much more expensive than others.


The group of silicone sealants, which are used in living quarters, can be attributed to sanitary facilities. There are no toxic components in them, and they have a minimum shrinkage percentage, and therefore the seams will remain tight and strong for a long time. Due to the fact that the product is elastic, it is useful for moving parts and joints. Often they are equipped with plumbing devices, including a toilet, a substrate is placed, and the joints are also covered.

Please note that, among other things, you can fill the joints between tiles where they are exposed to water with a sealant, close the joints between structures and walls, fix small glass products without screws, and additionally attach mirrors.

Advantages of silicone sanitary sealant

A huge advantage of silicone-based sealant will be the ease of work with it and the ability to install plumbing fixtures with your own hands. The tool is universal, suitable for a huge range of actions in the kitchen, bathroom, steam bath, sauna and pool. Other advantages:

  • Resistant to ultraviolet radiation, and still no fading in the light.
  • Suitable for all types of materials that are suitable for the manufacture of sanitary ware - faience, cast iron, acrylic and ceramics.

  • Resistance to high and low temperatures, humidity, drops, excellent tolerance of direct contact with water.
  • The presence of a fungicide in the composition, and also protection of surfaces from mold of fungal colonies.
  • Great strength, and also high adhesion to the substrate.
  • Shiny and smooth seam surface after drying, and also beautiful appearance.
  • Elasticity and the ability to stretch / contract with the main material.

  • Resistance to household chemicals and other aggressive substances that can get on the seams.
  • Safety for people and environmental friendliness.

How to choose the right product?

The right choice

There are silicone sealants on sale in various packages - tubes , cartridges and sprays. The cheapest will be the usual for all compositions in a tube, which have elongated noses.Sealants in the form of cartridges require the additional purchase of a special gun.

Usually they are bought for processing huge premises.

Please note that silicone sealant is required not only to be used correctly, but also to be acquired with a serious approach to issues. To begin with, you should choose a composition that is suitable in shade, although usually masters prefer white or transparent products. There are also some factors to consider.

Shelf life

Sometimes expiring toilet silicone sealant is sold at a huge discount.

You should not be led to tempting offers - usually the funds are very thick, have less elasticity and ways to partially lose the rest of the useful characteristics, and even more so fungicidal.

Intact packaging

If there is even a very small crack on the body of the sealant, it dries quickly from contact with air. When buying, you need to make sure that the integrity of the tube or other packaging is fully preserved. After uncorking, you should cover all the necessary places literally in 3-4 days, otherwise the sealant will begin to dry out.

Manufacturing company

Verified and reliable brands produce high quality goods.

Such means as "Titan", "Moment", "Knauf" could recommend themselves the best. The disadvantage will be the higher cost, because the popular brand always has an overpriced product.

Place of purchase

Sealants are sold everywhere, even in supermarkets. You should not buy them on the market by hand, for this there are special departments in the market or construction / hardware stores, where the goods are definitely not expired.

Application when installing the toilet

To install the toilet on the sealant, you must perform the entire sequence of actions correctly.

First, buy all the most necessary materials, prepare consumables and devices:

  • Choosing the best toilet sealant Sealant directly.
  • Laundry soap.
  • Silicone Thinner (if necessary, tear off and remove excess sealant or remove old compound).
  • Marker.
  • Glass drill and door.

  • Stationery knife.
  • Construction tape.
  • Rubber or plastic spatula.
  • Cotton napkin.
  • Degreasing agents - acetone and alcohol.

Now the preparatory stage.

Preparatory stage

Most often, toilets with oblique, vertical or even horizontal outlet are installed on the laid tiles. For this reason, it will be necessary to carry out the work carefully so as not to spoil or break the tile. In order to choose the correct position for plumbing, you must first connect the corrugation to the drain. Before installation, you need to:

  • Close off water access.

  • Clean the entire area.
  • Wash the bottom of the toilet bowl, wipe the joint with alcohol to degrease.

Consider the next step.


To glue the toilet with a sealant, you need to mark the entry zones of the anchors on the floor using a marker that can be easily erased from the tile, and then circle toilet bowl along the contour. Next, remove it, and glue the areas around the contour with construction tape.

This will make it possible to keep the surface clean.

Preparing the hole

Through the door it is required to make holes in the floor, where you will need to install the bolts. It is important to turn off the impact mode of the drill in advance so that cracks do not form on the surface of the tile. For a concrete floor, such a drill will not work, and you will need to buy a victorious one. After the holes are ready, clean them from dust with a vacuum cleaner or dry cloth.

Applying the agent

Pour a little agent into the holes so that the anchors hold much stronger. Also, the sealant will serve as a waterproofing, and water will not enter the holes. The order of work is as follows:

  • Apply sealants in a thick layer along the marked contour.
  • Install the toilet and press it down as best as possible.
  • Attach the device to the anchors, and put a rubber gasket under the head of the attachment.

  • Wipe off excess sealant or wipe off immediately with a napkin.
  • Remove the construction tape.

Please note that if the toilet feet are cracked, it can also be sealed with sealant. To cover up the bottom of the entire flaw, the break, completely hiding it and slightly going beyond the edges. With a spatula, you need to level the product, and then immediately rinse the tool in soapy water, otherwise the product will stick tightly.

The crack is also treated with the same soapy solution over the applied product and smoothed with fingers until smooth, if a spatula is not available.

Application of sealant in old sanitary facilities

Silicone-type paste can be used for partial repairs of an old toilet, the joint of which with the floor surface has already lost its strength ... To do this, proceed as follows:

  1. Prepare the substrate - remove dirt, rust, old sealant and plaque.

  2. Degrease the surface.
  3. Buy a sealant in a cartridge, and insert into a construction gun.
  4. Run the product over the seam so that it goes deeper under the fixture, making a continuous line.
  5. Remove excess composition with a cloth.
  6. After a few minutes, start shaping the seam with a rubber spatula (you can do everything with your hands in rubber gloves) - the goal will be to level the silicone to the level of the surface that has been processed.

  7. After hardening, the drops and uneven seam must be cut off with a utility knife.

It happens that the cuff on the toilet, which is applied to the sewer pipe, has lost its tightness. It can also be replaced with a sealant.To do this, remove the adapter with the cuff from the rubber pipe seal, and remove the latter, clean and dry. Buy new items 0 cuff, seal and adapter.

Apply silicone sealant to the pipe, insert the rubber band, then lubricate the cuff with a similar compound and secure in place.

Recommendations for application

To make the seam last long, you must follow the rules when working with toilet sealant:

  • Maximum the permissible joint width is 0.5 to 3 cm.
  • The thickness of the joint can be up to 1 cm.
  • Possible application depth up to 6 cm.

  • For very large defects, additionally use plumbing tape.

Compliance with tips and an algorithm of actions helps to do the work with high quality with your own hands without involving specialists and unnecessary expenses.
