21parkhouse flexible stone is an eco-friendly material and holds environmental certifications such as the UL certification (United States) and the Green Label certification (Singapore). The ENF environmental standard refers to the harmful substance testing for materials, which is a different type of standard than the one applicable to flexible stone.
The wood grain series of flexible stone has a natural texture that closely resembles real wood. The effect is authentic and stable, and it is also easy to install, cut, and work with, providing a convenient and realistic wood-like appearance.
We provide a 2-year warranty on the product, covering issues such as powdering, cracking, delamination, and color fading. The manufacturer also offers product and installation guidance and can recommend professional installation teams. However, issues arising from improper installation, such as cracking of the base layer, uneven surface preparation, rainy weather during installation, or failure to use the recommended adhesive, are not covered under the warranty.
The national industry standards for radiation testing mainly apply to natural mineral materials like marble. Flexible stone does not emit radiation and is free of radioactive substances.
No, flexible stone undergoes sterilization and anti-mold treatment, making it resistant to mold growth and less likely to be affected by humidity.
Efflorescence on flexible stone is typically caused by improper waterproofing of the base layer or the use of alkaline adhesives. If efflorescence occurs, the affected product should be replaced. Before installation, ensure proper waterproofing of the base layer, avoid using alkaline adhesives and grouts, and use flexible stone's dedicated adhesive. Additionally, avoid installation during rainy weather to effectively prevent efflorescence.
No, flexible stone will not powder. It has undergone strict 2000-hour aging tests, equivalent to 40-50 years of use on interior/exterior walls, without powdering, cracking, or delaminating. During the cutting process of small samples, a small amount of dust may appear on the surface, but this is not a sign of powdering from the product itself. You can use it with confidence.
Flexible stone should be installed using the dedicated eco-friendly adhesive designed specifically for it. The adhesive consists of two components: A dry powder and B emulsion. These components are mixed thoroughly before use, similar to a cement slurry. The adhesive has been tested and found to be free of harmful substances like formaldehyde and TVOCs. Inspection reports are available upon request.
It is recommended to apply the adhesive with a full coverage of 90% during installation, with an optimal thickness of approximately 2-3mm.
