How to choose the right tile adhesive

Are you interested in tile adhesives and want to learn how to choose the best tile adhesive and about their ISO standards and types? You're in the right place! In this section, we will provide you with all the important details about tile adhesive standards and the different types available. Whether you're a DIY enthusiast or a professional in tiling, understanding these standards and types will ensure successful tiling projects. Let's start by exploring the types of tile adhesives and their adherence to international standards. Tile adhesives are essential for keeping tiles securely in place and maintaining the beauty of our spaces. However, with numerous types available, it's crucial to understand the basics for optimal results. In this blog, we aim to simplify the fundamentals of tile adhesives, shedding light on the standards that govern them and their impact on tile fixing efficiency.

About ISO Standardization

ISO 13007 Classification: Ensuring Quality and Performance in Tile Adhesives

The International Organization for Standardization (ISO) is responsible for maintaining quality and consistency in various industries. In the case of tile adhesive, ISO has created specific standards for manufacturers and users to follow. These standards, known as ISO 13007 - 2010, ensure that tile adhesives meet important criteria like strength, durability, and suitability for different applications. ISO 13007 is crucial in maintaining quality in the tile adhesive industry, giving manufacturers a framework to ensure the reliability and effectiveness of their products.

Understanding the ISO Classifications of Types Of Tile Adhesives

Tile adhesives are not one-size-fits-all. There are different types to choose from, each designed for specific applications and conditions. Adhesives are classified based on their chemical composition. We've got three main types:

C – Cementitious tile adhesive: These tile adhesives are made from a combination of cement, sand, and other additives. They're commonly used for bonding materials like tiles, stones, and ceramics. These tile adhesives come in different classes based on how well they stick and how flexible they are. They undergo tests to check their tensile adhesion strength in different curing conditions. Depending on the results, they can be classified as Class 1 (C1) for normal adhesive or Class 2 (C2) for improved adhesive.

The table below shows the properties against each test condition for Class 1 and Class 2 cementitious adhesives-

D – Dispersion tile adhesive: These adhesives are made by dispersing polymers in a liquid. They're great for bonding materials like wood, paper, and fabric. Dispersion adhesives can also be classified into different classes based on the results of adhesion strength tests. The normal adhesive class is called D1, while the improved adhesive falls under class D2.

R - Reaction-resin tile adhesive: These adhesives are created through a chemical reaction between two or more components. They're often used for bonding materials like plastics, metals, and composites. Reaction resin adhesives are actually classified into different categories based on their properties and performance. R1 adhesives are the standard or basic reactive adhesives, while R2 adhesives are an improved version with enhanced characteristics. These improved adhesives offer better strength, flexibility, or other desirable features compared to the standard ones.

Specialized Tile Adhesive Features

In addition to the basic characteristics we discussed earlier, there are a few other optional classes that can give you more information about tile adhesives.

F - Fast-setting: This means that the adhesive will dry or set quickly, which can be really handy if you're in a rush or need to move on to the next step of your project as soon as possible.

T – Slip Resistance: This feature ensures that the adhesive will stay in place and not slide down when applied to vertical surfaces. It's great for ensuring accurate and precise application.

E - Extended open time: open time refers to the amount of time you have to work with the adhesive before it starts to set. Having an extended open time means you'll have more flexibility and won't have to rush through your work.

S - Special deformable: This is a unique feature specific to cementitious adhesives. It means that the adhesive has the ability to flex and accommodate slight movements or changes in the surface it's applied to. We have two classes within this classification: S1, which is deformable, and S2, which is highly deformable.
