How to apply the adhesive for tiles?

• Always ensure that the base surface for tiling is clean, flat, smooth, and firm. If any of these is missing, do not start the installation of tiles. A clean and dust-free surface is mandatory. 
• Start by preparing the adhesive in a large container – 20kgs US measurements of tile adhesive should mix with 5kgs US measurements of clean water.
• Stir the mixture vigorously to get a paste-like consistency and not runny or tight. You can add an adhesive enhancer to this mix to get the right texture, and NOT cement.
• Ensure there are no particles or lumps in this mix for smooth application. Leave it for a few minutes and stir again before applying it to the tiles. Remember that any configured tile adhesive will not last beyond 5-6 hours. So, make the most of it within that time.
• Use a professional trowel for applying the mix at the back of the tiles directly onto the substrate. Start by applying one square meter of the construction surface at a time and then move ahead. Never try to apply the whole area in go and then tile – this is not a smart approach.
• Apply a thin coat of adhesive to the substrate using the flat side of the trowel, and while smoothening it, install the tiles one by one.
• Use additional adhesives and comb ridges by holding the trowel at a 45-degree angle in straight lines. This technique will ensure that the tiles are at equal height and support the tile properly.
• Affix the tiles firmly into the adhesive – you may move the tiles to adjust back and forth but not side to side. You may also lift the tile periodically to confirm 80% of coverage.
• Once all the tiles are in position – leave them for drying. Clean the surface immediately, after it dries up – cleaning will be a hassle.

Conclusion 

Never apply more adhesive. More adhesives do not ensure better fixing of tiles but would rather ruin the shower tiling. You may require 24-73 hours to dry the adhesives before grouting.
