Can I glue the ceiling tiles on the whitewash and how to do it right?
For the treatment of ceilings using an impressive number of different building materials, one of the most popular options is the ceiling tile. It is relatively inexpensive, and you can glue it yourself without involving specialists.
If the ceiling has a layer of old whitewash, the preparatory work usually begins with its removal. But sometimes you can skip this point. Before you glue the ceiling tiles on the whitewash, you need to assess the state of the rough surface.
In which cases do they remove whitewash
To find out if it's possible to glue a tile on a whitewashed ceiling, first you need to find out what type of material was used for the finish. If it is based on chalk, then the layer will have to be removed. The fact is that such a coating can not withstand the weight of the products and very quickly begins to crumble.
If it is visually evident that whitewash is swollen and crumbling, then it must be completely removed
If it comes to lime, whitewash needs to be removed in the following cases:
- The material began to fall off the surface.
- There are several layers of coating on the ceiling.
- For processing, frozen lime was used.
Swipe the ceiling with a spatula, if the whitewash easily leaves the base, then it needs to be removed, and the rests are washed off with a sponge and warm water
What kind of glue to buy
Before you paste the ceiling tiles on the whitewash, you should choose the right composition. The main rule - do not use materials based on water, because whitewash can get wet, and products fall off. Most often for these purposes use glue "Titan". It is diluted with alcohol in proportions of 1: 1 or 2: 1. In addition, experts recommend the use of one of the formulations:
- Liquid Nails.
Ceiling panels are preferably glued to polymer compounds
After selecting the glue, all the necessary tools are prepared. To paste tile products, you will need:
- sharp knife;
- narrow metal spatula;
- marker or pencil;
- roulette or ruler;
- paint cord.
When gluing a light ceiling tile, you can get by with an accessible tool
Also it is required to prepare the finishing material, skirting boards for masking the seams, everything necessary for the preparation of glue and rags for removing its residues.
The first thing to check the state of whitewashed ceilings, for this you need to hold your hand over the surface. If the traces on the skin do not remain, then the coating is still quite strong. In places of obvious peeling, it is recommended to scrape a little with a spatula to remove weak fragments. Then, sweep up the formed dirt with a broom or a dry rag. At this stage it is important not to wet the coating, so that it does not go away.
Even if the whitewash keeps firmly, in any case before the arrangement it is desirable to apply a couple of layers of deep penetration soil
To qualitatively paste the tile, the ceiling must be leveled. Otherwise, individual fragments do not dock, and the overall pattern will be broken. It is necessary to do the following:
- Using the water or laser level to determine the lowest point of the ceiling - this is the zero mark.
- Using the same tools, measure several values on opposite and adjacent walls.
- The points are connected by means of a tape measure and a marker.
The ceiling can be laid horizontally with an inexpensive hydraulic level
The result is a level around the perimeter of the room.
If the ceiling slab is from 0 to 5 mm, it is enough to use the finishing putty to smooth out the difference, 0.5-1 cm - you should apply the starting mixture and reinforce it with a sickle. If the unevenness is more than 1 cm, it is recommended to mount drywall sheets for leveling. After complete drying of the putty, several layers of primer are applied at intervals of 3-4 hours. This is required to increase the adhesion of the surface and ensure a tight contact with the adhesive.
First of all, it is necessary to determine where the average row of material will be laid. Standard tile sizes are 50x50 cm, so you need to count how many pieces in the cross strip. Let's say the ceiling width is 3.5 m, which means that 7 elements will fit on it. The central line will pass between three rows on each side. If you get an even number, then it will be at the junction of the tiles, if the odd number - get to the center of one of the rows.
When marking the ceiling, you should push off from the center of the room, but take into account the location of the light source
Based on the data obtained, it is necessary to mark up the bands, while checking the level as often as possible. If the wall markings are not in a straight line, it's okay - the tile can be cut and hide the ugly edge. For beginners, it is recommended to install at a right angle, installing diagonally requires a longer and more rigorous preparation.
Diagonal installation of the tile looks more impressive, but the layout for it is different
Important! When planning the surface, you need to make sure that the drawings at the joint of the ceiling and walls are the same.
Before gluing the material, it is necessary to sort it out. All without exception, types of ceiling tiles are produced with inaccuracies, so the most substandard products are best left under the trim for the last rows. You can also take into account the presence of oversized products at the markup stage, but it will be quite long. The sequence of actions is as follows:
- Cut the material to the desired size.
- Apply adhesive to the center of the tile and around the edges. If the product is thin, then it is better to do it pointwise, otherwise - a continuous strip.
The method of applying the glue depends on its consistency and type
- Attach the fragment to the middle row of the ceiling and carefully fix it on the marked markings. Press the product against the surface and wipe off excess glue.
- Hold the tile for 2-3 minutes until the composition dries. If there are traces of depression, it is better to use a wooden or metallic rule.
- So stick all the products. Cut the last fragment and fix it as well.
- Treat joints with a special trowel using a rubber spatula.
- At the very end you need to close the walls and ceiling with skirting boards. Usually they are installed on glue, but there are heavy models that require more reliable fastening.
Fixing of panels and skirting boards is carried out on the same principle
The decoration of the whitewashed ceiling with tiles practically does not differ from the installation on clean surfaces. The main thing is to carefully check and prepare the cover.
