Yes, tiles can be covered with adhesive tiles. Adhesive tiles, also known as peel and stick tiles, are designed to be applied directly onto existing tiles or other smooth surfaces. This can be a quick and easy way to update the look of a space without the need for extensive demolition or installation. However, it is important to ensure that the existing tiles are clean, dry, and free of any loose or damaged pieces before applying the adhesive tiles for the best results. **

The design of tiles refers to the pattern, color, shape, and texture of the tiles. It encompasses the aesthetic elements that make up the visual appearance of the tiles. The design of tiles can vary widely, from simple solid colors to intricate patterns and textures. The design of tiles is an important consideration in interior design and can greatly impact the overall look and feel of a space. **

One way to cover up unsightly tiles is to use peel-and-stick tile decals or vinyl stickers. These can be easily applied over the existing tiles to give them a fresh new look. Another option is to paint the tiles with a special tile paint that is designed to adhere to the surface and provide a durable finish. Additionally, installing a new layer of tile or using adhesive-backed tile sheets can also effectively cover up unsightly tiles. **

To lay polygonal tiles over old tiles, you first need to ensure that the existing tiles are clean, dry, and in good condition. Next, apply a bonding agent or primer to the old tiles to help the new tiles adhere properly. Then, use a thin-set mortar to lay the new polygonal tiles over the old tiles, making sure to press them firmly into place. Finally, grout the tiles once the mortar has set to complete the installation. **

To remove floor tiles under wall tiles, you will need to carefully chip away at the grout and mortar around the edges of the floor tiles using a chisel and hammer. Once the grout and mortar are loosened, you can carefully pry up the floor tiles using the chisel and hammer. Be sure to work slowly and carefully to avoid damaging the wall tiles. After the floor tiles are removed, you may need to clean and smooth the surface before installing new tiles. **

The decision to remove or cover up the tiles depends on the condition of the tiles and the desired outcome. If the tiles are in good condition and the goal is to update the look, covering them up with a new material such as vinyl, laminate, or carpet may be a cost-effective and efficient solution. However, if the tiles are damaged, outdated, or pose a health risk (such as asbestos tiles), it may be necessary to remove them before installing new flooring. It's important to assess the condition of the tiles and consider the long-term implications before making a decision. **

When laying tiles on tiles with underfloor heating, it is important to ensure that the existing tiles are in good condition and securely attached to the subfloor. The underfloor heating system should be tested and functioning properly before laying the new tiles. It is also important to use a flexible adhesive and grout to accommodate any movement from the heating system. Additionally, it is recommended to use larger tiles to minimize the number of grout lines, which can help to distribute the heat more evenly. Finally, it is important to follow the manufacturer's guidelines for both the underfloor heating system and the tile installation to ensure a successful and safe installation. **

It depends on the condition of the existing tiles and the desired outcome. If the tiles are in good condition and the goal is to simply update the look, painting the tiles can be a cost-effective option. However, if the tiles are damaged or outdated, replacing them with new tiles may be a better long-term solution. Consider the cost, time, and effort involved in both options before making a decision. **
