Multi-functional (Tile Waterproof) Backing Board Introduction 1

What is a Backing Board?

When building or renovating your home, you will use tiles, marbles or mosaics. They add a personal touch and make the house more beautiful.

Therefore, we pay great attention to the choice of color, area, size and installation. However, all this effort is in vain, because external pressure (such as temperature changes, sunlight, frost, humidity or mechanical) will cause the tile adhesive to corrode and damage the building. What is the reason? Please continue reading.

Backing boards have high performance, made of waterproof extruded polystyrene, with glass fiber mesh embedded in the mixture on both sides, which enhances the strength and hardness of the board. Jieai backing boards are suitable for various new and renovation projects. They have high waterproof and anti-corrosion properties, making them the perfect solution for wet areas such as bathroom walls, showers and humid rooms. The board is light in weight, easy to handle, and can be easily cut with a sharp knife. It can reduce heat loss to the floor and reduce the time it takes for the floor to reach the desired temperature.

It also reduces power costs. Backing boards can be tiled to the surface of floors or walls, and for wooden floors and plaster walls no mechanical fitting is required. For wooden studs: only 10mm boards are needed, fixed with screws and washers.

Material Composition

This product is made of extruded polystyrene as the core, with a mixture of glass fiber mesh embedded on both sides.

Surface

The surface is a layer of waterproof polymer mortar, embedded with a layer of glass fiber mesh cloth.

Color

Its surface color is medium gray, with a light blue edge.

Shape

The board is rectangular, but can be cut into any shape.

Limitations

Backing boards are suitable for framing structures and other suitable bases. But they cannot be used on vinyl materials or as structural components.

Adhesion and Waterproofing

All joints of the board are sealed with adhesive tape. Tiles are fixed with cement mortar, so they can significantly resist the transmission of water vapor.

Fire Resistance

After installation, the fire resistance of the wall will not be affected. It can reach EN13501-1 flame retardant grade B, and concealed lighting should not use this form of insulation.

Thermal Insulation

The thermal insulation provided by this board is durable. The thermal conductivity of polystyrene is 0.035w/(m.k).

Multifunctional (Tile Waterproof) Backer Board Description 2

Other lightweight objects can be fixed to the backer board using professional fixing methods.

Durability

The durability of this material is very satisfactory. The board complies with building requirements and has stable and long lasting backing. Under normal conditions, it has a service life equivalent to that of the building, and will not be damaged. However, if damage or wear occurs, it is also convenient to repair.

Impact on Indoor Environment

The backer board is classified as non-emitting for any particles, toxic gases, or radiation, and will not affect indoor air quality or pose a significant impact on human health.

Environmental Statement

The backer board does not contain hazardous substances listed by the European Union environmental organizations.

Waste Disposal / Recyclable

After the service life ends, the backer board can be sent to a public waste treatment site for disposal.

Storage and Transportation

During storage or transportation, the backer board should be covered with clean material to avoid dust and dirt reducing the surface's adhesive properties. The board should not be exposed to fire, high temperature, or organic solvents. When stored, avoid long-term ultraviolet radiation.

Advantages

Areas of Application

wedi Joint Sealant is especially formulated for excellent adhesion to wedi extruded polystyrene foam (XPS) products, wedi cementitious-based surfaces, modified thinset mortars, concrete, aluminum and glass without primer. This sealant can be used to waterproof and connect parts of wedi system assemblies and adds high bond strength and flexibility to the joints. In addition, wedi Joint Sealant is paintable once cured, non-staining and recommended for applications requiring expansion and contraction.

NOTE: wedi Corp. cannot be held liable for any claims related to the use of this sealant with other foam-based products

Instructions For Use

Substrate Preparation:

➢ Apply directly to wedi extruded polystyrene foam (XPS) products and/or wedi cementitious-based surfaces. ➢ Other substrates must be clean, dry, free of dust, oil, grease and any contaminants that could harm bonding. ➢ Clean substrate with methylethylketone (MEK), acetone or a special degreasing agent. ➢ Apply a primer if necessary. ➢ Check the compatibility of the solvent used with the substrate. ➢ When using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer.

Caulking:

➢ wedi Joint Sealant can be applied with a manual or pneumatic gun. ➢ After application in between wedi assembly parts, use a putty knife to smooth out any excess sealant and work it into the weld surface entirely covering the joints. Where the sealant is used in between wedi parts, make sure that they are pressed together firmly. ➢ This sealant should be used within 24 hours of opening or it could harden in the cartridge. ➢ Do not apply at temperatures below 40 °F. ➢ In cold weather, store the sealant at 68 °F for 24 hours prior to use. ➢ Avoid any contact with non-cured MS, hybrid PU or silicone sealants as well as alcohols or ammonia during curing.

Cleaning:

Tools can be cleaned with MEK or acetone before the sealant has completely cured. After curing, abrasion is necessary.
