The modern market for building and finishing materials is quite wide, but the leaders in this area have long been defined. One of the best materials for facing is ceramic tiles. The base, which is tiled, is practical and will last long enough. The presence of a large color palette allows any design projects. The popularity of this material can also be explained by the fact that the process of wall finishing with tiles is simple.
To ensure that the tile looks neat after laying, it is necessary to grout the joints.
After the tiling is laid, grouting is performed. This process is not very complicated, but without this, the finishing of walls and floors can not be considered complete. In addition to practical significance, the seams also perform a decorative function - they complement the image on the wall or floor base. For today in the market it is possible to find a plenty of various color additives.
Types of grouts
Grout, which in its composition has cement, is sold as a dry mixture, which can be brought to a proper state by diluting it with water. On sale it is possible to find ready-made solutions, however they are much more expensive than dry mixtures. Grout from cement is most often made from Portland cement, some additives are present in the composition. Grout of this type can be divided into the following types:
- compositions from industrial portland cement;
- compositions with a dry hardener;
- compositions based on latex and Portland cement.
To avoid problems when grouting joints, it is necessary to choose a mixture that fits your tile.
Epoxy grout is made from a suitable resin and hardener, it is able to give seams increased strength. Such a composition is quite expensive. In most cases, it is used to equip commercial and industrial premises. Epoxy grout is viscous, because it can only be used by specialists. In addition, there are some limitations of its use: the thickness of the tile - from 1.2 cm, width - from 0.6 cm. In seams of a lesser thickness, such a grout can not get.
To avoid major problems when doing the work independently, you should carefully read the instructions from the manufacturers. Only in this way will it be possible to determine which trowelling mix is ideal for the existing tile.
Correctness of stacking
Be sure to perform the processing of seams using a sealant. This tool can protect the base of the tile from excessive water absorption, as well as protect it and seams from staining. If the base is trimmed with unglazed tiles, then it will need to be covered with a special sealant. This product consists of acrylic or varnish. It must be chosen in accordance with the type of tile and the material used for grouting.
To keep the tile from moisture and stains, you need to use a sealant.
Distance between tiles
Most often the width of the joint grout is determined based on personal preferences. Many prefer seams of small width, which visually suppress the tile. If the base is made of elements 10-30 cm in size, then the appropriate width of the seam will be 3 mm. In some cases, according to a similar scheme, tiles with dimensions of 60 cm are laid. If it is planned to use a tile of irregular shape, it is recommended to make seams of a larger width. The maximum width of the joint is 12 mm.
You should know that the wider the seam, the more likely it is that it will crack. To fix it, you'll need to use a grout with the addition of sand. However, even in this case it is impossible to be sure that the grout in the seams will not crumble.
Too narrow to make a grout grout is also not recommended, since the trowel works in this case will become more complicated. As a result, the seams can turn out to be leaky, so that water can penetrate the tile. The seams should be of such width that they could easily be filled with any grout. Only in this case they will be able to avoid moisture and perform a damping function in the process of compression and expansion of the tile.
To perform all the work you will need to prepare the following tools and materials:
Before doing any work, store the necessary tools.
- Respirator. It will be necessary in case of using a trowelling mixture based on cement.
- Points for protection.
- Gloves made of rubber.
- Spatula or scraper.
- Solution tank.
- Plywood sheet.
- Rigid brush.
- Clean cloth.
- Brush or roller of small size.
The sequence of actions will be as follows:
- The first step is to mix the grout.
- After this, you need to maintain the solution to the desired level of water absorption.
- Then again, mix the grout very well.
- The solution is distributed.
- The excess of the mixture is removed.
Preparation of the solution
Most often, dry grout is mixed with water or liquid additives from latex. It is worth remembering that a dry polymer mixture can be mixed exclusively with water.
Liquids should be added such amount that will be sufficient to obtain a plastic solution. Excessive amounts of water can cause the mixture to weaken. The solution should be mixed based on the proportions that are indicated on the package. The container in which it is planned to mix the mixture must be dry and clean.
During the mixing of the grout, the dry ingredient should be added to the liquid. First of all it is necessary to use ¾ of the liquid norm, which is indicated in the recipe. After the addition of all dry components to the solution, it is necessary to add liquid residues to the solution, and it is important to keep the consistency of the mixture under control.
When preparing mortar for grouting joints, you must strictly observe the proportions of water specified in the instructions.
The process of making the grout is influenced by external factors such as room temperature, relative humidity and the presence of dye.
To mix the solution, you will need to use a trowel or stirrer. If it is planned to automate the process, the stirrer should be immersed in the solution during operation, so that air does not penetrate it. It should be understood that air bubbles can weaken the trowelling mixture. Therefore, the blade speed should be less than 300 rpm. After the mixing procedure is completed, you will need to wait 10-15 minutes. After this time, the solution can be used for grouting.
Tiling the tile
Scheme of distribution of trowelling of tile joints.
This process begins with the distribution of the prepared mixture on the base of the tiles. To properly distribute the solution, it is recommended to use a small grater. It should be installed at an angle of 30 ° with respect to the base of the tile, the solution is applied diagonally. The grater should go through the whole area several times, while not only covering the distance between the tiles, but also trying to rub the mixture into the seam with effort so that it is completely filled. The greater the resistance, the more densely filled the seam. The main purpose of this process is to fill in all the voids and corners around the tile. In the process of distributing the grouting liquid from it will be removed, and the seam will be filled with grains of sand and cement. The result should be a solid body.
Do not use the entire substrate at the same time.
It is best to distribute the mixture in a small area - about 1-2 m². During operation, it will be possible to determine how quickly the mixture dries. This way you can determine whether you need to perform frequent stops that involve cleaning the bottom. Sometimes it is possible to simultaneously grind and 9-10 m?, Without performing the cleaning of the working base. If the mixture will quickly set, then only a small area should be rubbed.
When distributing the grout between the seams, it is first necessary to fill the horizontal joints.
If considerable effort is required to clean the base to be lined, it is best to use a special trowel. This product is similar in appearance to a confectionery bag with which women decorate cakes. At the end of the bag, you need to fix the tip, whose diameter corresponds to the width of the joint grout. After that, the bag will need to be filled with a mixture, which will be squeezed into the seam with effort.
In the process of using such a device, the tip should be located at the top of the seam, and then move it along. Most often the first thing to fill all the seams horizontally. When distributing the grout, it should be squeezed out slightly more than it might seem at first. After the solution has hardened, it should be compacted. To do this, you need to use a bar or a small piece of a smooth tube of metal, the diameter of which is greater than the size of the seam.
Then it will take 35 minutes to wait until the grout grasps. Then you need to remove all surpluses. For this purpose it is recommended to use a rigid brush.
After finishing work, remove excess grout with a damp cloth.
When the grout solidifies, you will need to perform a wet cleaning of the base, which is lined. To do this, use an ordinary sponge, which is soaked in clean water. Movement in a circle an extra grout should be removed from the tile. In the process, it is often necessary to wash the sponge in a liquid. Water changes as it gets dirty.
It is also possible to dry the mixture. In this case, the seams will need to be aligned and smoothed with the help of a binder. After this, the edges need to be trimmed with a sponge. The seams obtained should be smooth and not convex, most often they are concave. Seams should have the same shape and depth.
Grouting joints of tiles is not a difficult process. It will only be necessary to follow the sequence of actions and have all the necessary tools and materials available.
