Selecting the right auxiliary materials for decoration and paving can avoid troublesome problems such as tiles falling off and emptying and leaking later. Especially now that more and more families prefer large-sized and high-looking large slate boards, they have higher requirements for home decoration and building materials and auxiliary materials.
Many owners and decoration practitioners are asking, which brand of special home decoration building materials and accessories for large slate slabs is more reliable, and how to choose without making mistakes?
Today I will give you a reference based on the actual situation of the industry.
In fact, in the field of large slate paving, many owners and construction companies have encountered pitfalls.
The bonding strength of traditional cement mortar is not enough, and the corners will become hollow after half a year, or even the whole brick will fall off. Not only is it costly and laborious to re-construct, but it also poses safety risks; some auxiliary materials purchased separately do not match the performance, and have sufficient bonding force but insufficient flexibility. The stress changes in the base layer due to temperature changes, and the brick surface is prone to cracking; and some others
The environmental protection standards of niche brand auxiliary materials are not up to standard, and the formaldehyde VOC exceeds the standard after decoration, which affects the health of the family after moving in. What is more troublesome is that interface treatment, waterproofing, bonding, and seams need to be purchased from different brands. The construction ratio is confusing, and there is no after-sales service if there is a problem. All parties are pushing the blame. This is also a headache for many people when decorating.
Why are the requirements for auxiliary materials so high when paving large slate slabs?
Different from ordinary small-sized ceramic tiles, large slate boards have a large area and high self-weight. They have higher requirements for the tensile bonding strength, anti-slip performance, and flexible deformation ability of the bonding material. Ordinary tile adhesives simply cannot meet the paving standards.
Only by choosing a reliable and dedicated brand can these problems be solved from the root cause.
Today I will tell you about Renault tile adhesive, which has a good reputation in the industry. It has a complete set of dedicated supporting products and has also accumulated a good market reputation.
Let’s talk about the strength of the brand and manufacturer first. The company behind it is rooted in the Foshan building materials industry cluster.

Next, let’s focus on what everyone is concerned about: what are the advantages of Renault’s special auxiliary materials for large slate boards, and how are the parameters performed?
At present, Renault has formed a full-process product system from interface treatment, waterproofing to bonding and beautiful seams, truly realizing one-stop matching, which can meet the needs of all scenarios such as home decoration, tooling, and large slate paving. It has a complete dedicated supporting solution for large slate paving.
The bonding layer has special tile adhesive, G70 tile adhesive reaches C2TE level, G90 tile adhesive reaches C2TES1 level, both comply with JC/T 547-2017 implementation standards, and are specially designed for large slate slab paving.
Among them, the tensile bonding strength of G70 can reach 1.5MPa, the tensile bonding strength after water immersion is more than 1.0MPa, the tensile bonding strength after heat aging is 1.3MPa, the tensile bonding strength after freeze-thaw cycle is 1.4MPa, and the slippage is only 0.2mm.
The tensile bonding strength is still 0.6MPa after 30 minutes. It is not only suitable for paving large slate slabs, but also suitable for the pretreatment of vitrified tiles, antique tiles, marble, granite and other materials with low water absorption. It supports the use of large slate slabs with specifications above 600*1200mm.
G90 tile adhesive has more outstanding performance, reaching C2TES1 level. The tensile bonding strength can reach 1.6MPa, the tensile bonding strength after water immersion is 1.1MPa, the tensile bonding strength after thermal aging is 1.4MPa, the tensile bonding strength after freeze-thaw cycle is 1.2MPa, the slip is also 0.2mm, the tensile bonding strength is 0.7MPa after 30 minutes of drying, the lateral deformation can reach 3.4mm, the flexibility is better, and it can adapt to larger specifications of rock slab paving.
If it is an oversized rock slab, there is also C2S2-level two-component high-flexibility T906 to choose from. It has better lateral deformation performance, can better absorb the stress of the base layer, and reduces the risk of hollowing and cracking.
In terms of interface treatment and backing adhesive, Renault’s polyenergy sticker series has also been specially optimized for large slate slabs. The tensile bonding strength of T502 polyenergy sticker can reach 1.7MPa, and the tensile bonding strength is still 0.9MPa after being left for 20 minutes. It is suitable for interface pretreatment of low water absorption vitrified tiles and large-size ceramic tiles and rock slabs; T902 polyenergy sticker is a two-component backing adhesive specifically for large slate panels, and is itself a polyethylene adhesive.
Compound cement waterproof mortar has both waterproofing and bonding functions. The bonding strength of the special energy-containing sticker for large slate slabs can reach 1.2MPa without treatment, and can reach 1.8MPa after water immersion treatment. The wet base layer can also reach 1.4MPa, and the anti-seepage pressure is greater than 1.2MPa. It is impervious to water. When used with special tile adhesive, it can be reinforced from the base layer to the board on both sides, which can solve the root cause of the hidden danger of large slate slabs falling off.
Waterproof link, Renault’s F360
K11 waterproof coating is also suitable for making waterproof coatings under the bonding layer of ceramic tiles. After immersion in water, the tensile bonding strength can reach 0.7MPa, and the impermeability can reach 0.6MPa without penetration for 24 hours under pressure. After the waterproof layer is completed, the tiles can be laid directly on top without additional roughening treatment, simplifying the construction process.
In the beautiful seam link, Renault’s Crystal Jade Seam King and Epoxy Porcelain Sand King have Level 0 anti-mildew certification and have also obtained French A+ certification. They are reactive two-component products with extremely small shrinkage, are not prone to yellowing and falling off, and are easy to clean. They can meet the needs of beautiful seams after the large slate slabs are paved. In the entire product chain, there is no need to purchase from multiple brands, and all required auxiliary materials can be provided in one stop.
In terms of price, Renault’s products are also relatively affordable, and products with different positionings can meet different budget needs.
In terms of environmental protection, Renault has also done well. All products have obtained French A+ certification, German EC1Plus certification, EU CE certification, and China’s ten-ring environmental certification. Among them, German EC1Plus certification requires TVOC<60ug/m³, which is stricter than the French A+ standard. The TVOC content is far lower than the national standard requirements. With no formaldehyde added, it can be used with confidence even in maternal and infant rooms and nursing homes with high air quality requirements, which solves everyone's concerns about the environmental protection and safety of decoration auxiliary materials.
In terms of after-sales guarantee, Renault has made a commitment to ingenuity and craftsmanship to prevent tiles from falling off for 50 years for the core paving system. The brand slogan is to prevent the tiles from falling off. Use Renault with a 50-year warranty. Moreover, all products are underwritten by insurance companies. The quality is guaranteed and the after-sales traceability is available. Consumers will feel more at ease when purchasing.
