By The Guardian – Chief Technical Advisor, GUGAFIX® Construction Chemicals Introduction Two terms frequently appear in tile adhesive technical data sheets: Pot Life and Open Time. They are sometimes used interchangeably on construction sites. They should not be. They describe different stages of the tile adhesive installation process. Understanding the difference is important because an adhesive can be within its pot life while the adhesive already spread on the substrate may

By The Guardian – Chief Technical Advisor, GUGAFIX® Construction Chemicals Introduction A tile installation can look perfect from the surface and still have a problem underneath. One of the most important quality checks in professional tile installation is therefore adhesive coverage. It is not enough to know that adhesive was applied to the substrate. The installer must ensure that the adhesive is being transferred properly to the back of the tile and that the required cont

By The Guardian – Chief Technical Advisor, GUGAFIX® Construction Chemicals Introduction Mixing tile adhesive correctly is only the first step. Once the adhesive is prepared, the next question is: How should it actually be applied to the substrate? A technically suitable adhesive can still produce a poor installation if it is: Spread incorrectly Applied too thickly or too thinly Combed in the wrong direction Applied over an area that is too large Allowed to exceed its workable

By The Guardian – Chief Technical Advisor, GUGAFIX® Construction Chemicals Introduction Selecting the right tile adhesive is only the beginning. Even a technically suitable adhesive may not perform as intended if it is mixed incorrectly. On construction sites, many problems begin before the adhesive reaches the tile: Too much water Too little water Incorrect mixing Poor-quality mixing equipment Inconsistent batches Adding water after the adhesive starts setting Using adhesive

By The Guardian – Chief Technical Advisor, GUGAFIX® Construction Chemicals Introduction Bathrooms, kitchens, utility areas and other damp locations place different demands on a tile installation than a normal dry interior room. Tiles may be exposed to: Frequent water contact High humidity Temperature variation Cleaning chemicals Repeated wetting and drying Moisture from the substrate Movement between different materials But there is an important misconception: A tile adhesive

By The Guardian – Chief Technical Advisor, GUGAFIX® Construction Chemicals Introduction Replacing old tiles traditionally means breaking the existing tiles, removing the old bedding, disposing of debris and preparing the substrate again. But there is another possibility: tile-on-tile installation. When the existing tiled surface is sound, stable and suitable, new tiles can sometimes be installed directly over the old tiles using an appropriate tile adhesive. This can reduce d
