When tackling any tiling project, the foundation matters just as much as the visible finishes. That’s where PROVA BOARD® PLUS steps in, offering an unbeatable combination of durability, ease of installation, and moisture protection. This high-density tile backer board is designed to keep wet areas dry and secure, making it an essential component for any bathroom, kitchen, or wet room installation.
Unmatched Waterproofing Capabilities
PROVA BOARD PLUS features a 100% waterproof XPS (extruded polystyrene) core that stands up to vapor pressure and effectively blocks moisture penetration. By preventing water ingress, it ensures that mold growth is not supported, contributing to a healthier environment in your home.


Versatile Application
This versatile backer board is not just for bathrooms; it can be installed on walls, countertops, and even around fireplaces. Its robust construction makes it ideal for tub surrounds, walk-in showers, and even for building custom benches that remain dry and stable. Whether you’re renovating an old space or crafting a new one, PROVA BOARD® PLUS+ provides a reliable substrate for your tiles.


Support for Large Format Tiles
The strength of PROVA BOARD® PLUS+ lies in its ability to support large format tiles. Its stable, non-deteriorating, and non-rotting properties make it an excellent choice for heavy or large tiles that require a firm foundation to prevent cracking and shifting over time.



Installation Made Easy
Designed for quick and easy installation, PROVA BOARD® PLUS+ can be secured with PROVA FASTENERS® and sealed with PROVA-SEAL™ to ensure a completely watertight finish. This system not only speeds up the installation process but also guarantees that your tiled surfaces are protected from water damage, extending the life of your installations.
Durability and Safety
Beyond its waterproofing features, PROVA BOARD® PLUS+ is also highly durable and flame retardant, adding an extra layer of safety to areas prone to moisture and heat exposure. Its construction includes a tightly woven mesh sandwiched between layers of cementitious coating, which enhances its structural integrity and fire resistance.

Requirements for Use
It’s important to note that PROVA BOARD® PLUS+ requires premium polymer-modified thinset mortar for installation. The use of premixed mortar or mastic is not recommended, as these materials do not provide the same level of adherence and waterproofing needed for a secure and long-lasting installation.
Conclusion
With PROVA BOARD® PLUS+, professionals and DIY enthusiasts alike can achieve professional-grade results in any tiling project. Its superior construction, combined with easy installation and excellent protective properties, makes it the go-to choice for ensuring that your tiling work remains beautiful and durable for years to come. For anyone looking to upgrade their tiled areas, PROVA BOARD® PLUS+ offers the assurance and quality needed to do the job right.
