Levelling compounds: PCI products for work on walls and floors

Cracks in walls and floors frequently occur and may result in severe structural problems in the long term. To prevent severe damage, it is best to react when the first signs of cracks appear in walls or floors. Levelling compounds are ideal for sealing narrow and wide cracks. The various products in the PCI Periplan® and PCI Pericret® families are suitable for work on concrete, cement screed, wood and ceramic flooring. Thanks to the many variants available, we can offer the appropriate levelling compound for any repair or refurbishment project. The flowing properties of the compound are a key factor in ensuring that the product can be applied in a thin, even layer. We already give top priority to flow properties in production.

Levelling compounds for tiles: preparing and levelling the substrate

Special care must be taken in the preparation of the substrate. Even when tiles are to be laid on an old screed, it is still normally necessary to use a levelling compound. The product eliminates irregularities in the old covering and can also compensate for level differences within the room. 

PCI products have been designed to ensure optimum flowing and adhesion properties and to allow rapid processing if the user complies with the required mortar/water mixing ratio. Ideally, large quantities should be prepared using a paddle mixer to ensure that the individual components are thoroughly blended. However, you should only make up as much levelling compound as you can use within the next 30 minutes. If several layers of levelling compound are to be applied, it is recommended to start work on the next layer as soon as the previous layer can be walked on. 

Effective elimination of irregularities with special levelling compounds

Our levelling compounds also include self-levelling products such as PCI Periplan® Fein or PCI Periplan® Multi. The advantage is that it is not necessary to level these compounds after they have been applied. Critical substrates such as chipboards or wooden boards call for special fibre-reinforced levelling compounds– such as PCI Periplan® Extra. When this layer has been applied, the new tiling can be laid without any irregularities.
