GGCL Guide: What adhesive to use for porcelain floor tiles
In the process of covering your walls or flooring of your offices or home, it is equally important to select the type of adhesive you would be using. We use tile adhesive to stick our tiles to walls and floors. There is a wide range of variety of substrates and tile types with GGCL, therefore it is very vital that the correct adhesive is chosen to ensure your tiles stay in place for years to come. The different types of adhesives react differently with different substrates. So it gets elementary to identify and choose the ideal substrate based on your requirements.
Let us take a brief look at the most commonly used and available substrate options. For the wall tiles, walls are the prominent substrate. The walls are either plastered or the plasterboards are used in absences of plastered walls. On the floor, we either have timber floorboard or concrete. The timber floorboard consists of marine grade plywood (minimum 15mm thickness) or a tile backing board on top. While timber floorboard doesn’t require a longer dry off period, concrete bases generally require weeks of drying period before you can start working on it.
Based on the substrate you are working on, you can select between the ready mixed pastes and powdered adhesives. For the plastered walls and plasterboards, you can use ready mixed pastes if you are sticking small tiles. For larger porcelain tiles, powdered adhesive is more suitable. Ready mixed pastes can never be used to tile floors. You must always use the powdered adhesive. The main things to consider when choosing the right powdered adhesive are colour, flexibility and the open, or setting time. The colour of powdered adhesive should be matching with the grout. The flexibility of adhesive must be considered when the floor tiles experience lots of vibration or movement. The setting time must be considered because the faster the adhesive sets, the sooner you can get onto grouting and finishing your room.
