Silicone is considered to be more environmentally friendly than many other materials because it is durable, long-lasting, and can be recycled. It is non-toxic, does not leach harmful chemicals, and is resistant to extreme temperatures, reducing the need for frequent replacements. However, the production of silicone can still have environmental impacts, such as the use of fossil fuels in its manufacturing process. Overall, silicone is a better alternative to many other materials in terms of its environmental impact, but it is not completely without drawbacks. **

To lay polygonal tiles, start by preparing the surface by ensuring it is clean, flat, and dry. Then, plan the layout by dry-fitting the tiles and making any necessary cuts. Next, apply a thin layer of mortar or adhesive to the surface and carefully place the tiles, ensuring they are evenly spaced and level. Use spacers to maintain consistent grout lines and allow the mortar to set before grouting the tiles. Finally, clean off any excess grout and seal the tiles to protect them from stains and moisture. **

Polygonal tiles are laid on clay by first preparing the surface by cleaning and leveling it. A layer of adhesive is then applied to the clay surface, and the tiles are carefully placed on top, ensuring they are evenly spaced and aligned. Once all the tiles are in place, grout is applied to fill the gaps between the tiles and secure them in position. Finally, the grout is cleaned off the surface of the tiles to reveal the finished look. **

Yes, silicone does stick to silicone. When two silicone surfaces come into contact, they tend to adhere to each other due to their similar chemical composition. This property makes silicone a popular material for creating airtight seals and bonding silicone-based products together. **

Organic products are made from ingredients that are grown without the use of synthetic pesticides, herbicides, or fertilizers, and are often certified by a regulatory body. Eco-friendly products, on the other hand, are designed to have minimal impact on the environment throughout their entire lifecycle, from production to disposal. While organic products focus on the natural ingredients used, eco-friendly products consider the overall environmental impact of the product. In essence, organic products focus on the ingredients, while eco-friendly products focus on the entire product lifecycle. **

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. **

Polygonal slabs used for a terrace should have a strength that can withstand the weight of foot traffic, furniture, and other potential loads. A minimum strength of 3000 psi (pounds per square inch) is typically recommended for outdoor terraces to ensure durability and resistance to cracking. Additionally, the slabs should have good resistance to weathering and be able to withstand freeze-thaw cycles to maintain their integrity over time. **

It is generally not recommended to apply new silicone on top of existing silicone. The new silicone may not adhere properly to the old silicone, leading to potential issues with adhesion and durability. It is best to remove the old silicone completely before applying a new layer to ensure a proper bond and a long-lasting seal. **
