wedi Building Panels Over Structural Floors

Whether it is in new construction or renovation, a great variety of subfloor types need a tile underlayment prior to set-

ting tile or stone. Some of the reasons for the need to install tile underlayments include: they may reduce stresses from

subfloors and protect tile; they may be used to build up height as needed to finish the tile surface flush with adjacent

flooring surface; and they may be necessary for waterproofing or insulation purposes. Also very important, they should

provide and support successful and lasting adhesion performance for thinset mortar and tile. wedi Building Panels offer

a durable underlayment surface once tiled and it passes the Robinson Floor Test (ASTM C627) having achieved a “heavy

duty use“ rating. In combination with its ideal flat surface, it is a logical choice when installing either small tile or very

large tile but possibly extremely thin tile on floors. Both require perfect thinset mortar coverage and adhesion, made

easy when working on a most flat and even surfaces and they need the full support of a strong underlayment like the

wedi Building Panel. It is, however, important to evaluate the suitability of a subfloor structure, or the layer below a tile

underlayment, to ensure a proper tile installation and also the choice of a good underlayment fitting the application.
