Can I Put Tiles Over Painted Concrete Walls?

Tiles have a variety of nature and humanMake materials to make durable, attractive surfaces for walls and floors.Long Key-Proper substrate preparation is a long lasting and attractive tile installation.The finished tile work is very heavy and requires a base plate strong enough to support the weight.
In addition, the size of the tile ranges from square inches or less to a few square feet.Each tile must be installed separately, so the substrate must be flat to prevent uneven edges of the finished product.Before starting to install tiles on a concrete wall, check to find any damage to the concrete surface, signs of moisture penetration or areas that are clearly uneven.
If moisture penetration is found, please check with the tile manufacturer/distributor to be installed on the concrete;Some types of natural stone are not suitable for installation in wet environments.Tiles can still be installed if the concrete is damaged or the area is uneven.As long as the wall structure is reasonable and can support the extra weight of the tile, surface defects can be compensated during installation.
In order to apply on uneven concrete surfaces, lightweight waterproof building boards must be used as a replacement for cement boards in tile installation.The building boards are very light and easy to cut, but they provide a very solid, durable and waterproof surface that will be fitted with tiles on it.The building panels can be \"bonded on site\" with thinset, which is the process of applying the large thinset point to the side of the plate facing the concrete wall, about every 12 inch.
This process will be carried out on paint or bare concrete.If the concrete is sealed, better adhesion can be achieved by forming a rough surface on the concrete with a grinder.The board is then pressed against the wall and adjusted according to the Plumb and height.
Thinset will securely glue the board to the concrete surface, hiding all the surface defects on the concrete behind the building board, leaving the perfect level or even surface for the tile.It is best to start at the corner and measure and cut the first building board with a tool knife to determine the size.The panel is bonded to the concrete wall site using unmodified thin layer mortar.
Continue this process for subsequent panels to ensure that each newly installed panel remains horizontal and vertical with the previous one.Tiles can be set on the building board using unmodified thin plastering.The cut size of the spatula used may vary depending on the size and type of tile to be installed, but V-The slot trowels are usually preferred for wall installation.
Verify with the manufacturer/distributor of the selected tile to ensure that the appropriate cut size is selected.Starting from the bottom of the first building board, it is better to lay a thin layer on the surface with a spatula in the corner.Use a spatula to cut out the thin sleeve evenly and completely, and then remove the excess parts.
Lay a smooth thin cover on the back of the first tile and firmly lay it in the gap layer on the wall.Apply uniform pressure, force the air to leave the thin sleeve, and make firm contact between the thin sleeve layer on the tile and the thin sleeve layer on the wall.Check if the tiles are vertical and horizontal, then proceed to the next tile.
When installing each tile, check to verify that it is vertical and horizontal with the previous tile.Use the gasket as needed to keep the tiles in the right position.The tiles are ready after all the tile classes have been installed and thinset has a chance to dry.
For unpolished tiles, such as slabs, the sanding grout is usually appropriate, while the unpolished grout is suitable for polished tiles such as granite.Verify with the manufacturer/distributor to ensure proper grouting material is selected
