We all need roots that we can rely on, just like wood grown as trees with their roots holding them firmly into the ground. Give wood flooring that natural grip back and bond it into position. As in nature, a good bond must have certain flexibility to compensate for differential movement, such as between an inorganic subfloor and an organic wood floor. Sika’s wood floor installation systems are designed to meet the requirements of your selected wood flooring, your new or existing substrate or screed, your flooring contractor and the expectations of the owners and end users.

Sustainable, Long-Lasting Wood Floors are Our Standard

Sika’s elastic adhesives have now proven themselves over many years, giving wood floors a durable, long-lasting, flexible but firm and resilient bond to the substrate. Our latest products continue the development of this expertise and follow the path of sustainable bonding with adaptable mechanical properties, all to the latest and highest environment, health and safety (EHS) standards.

Wood floor laying is a complex subject, where several parameters must be aligned to achieve good results. In addition to local construction practices, climates and regulations, manufacturers’ specific instructions for wood floor products must be checked before confirming the most appropriate system and build-up.

Sika Provides a Complete Wood Floor Installation System – From Level to Varnish

Laying a wood floor starts with the analysis and preparation of the screed and ends with varnishing or oiling the wood floor. At Sika we have the products and expertise to help you achieve the best results in all situations. Our system solutions are designed to be balanced, giving your wood floor protection and firm adhesion below, with protection and shine from above. Choose Sika system solutions for the complete installation process from leveling to varnishing.

Subfloor and Screed Characterization

A prerequisite for a sustainable and beautiful wood floor is a strong and dry screed. Therefore this screed has to be carefully accessed.

Screed Repair and Preparation

If the screed is even, strong and dry enough, then only mechanical surface preparation such as grinding and cleaning is required, before wood floor bonding is possible.

Pretreatment Priming Solutions for Substrates

Primers can have several roles in preparing the floor surface for leveling, filling or the actual wood floor installation itself. Priming the substrate will generally improve adhesion, limit the absorption of the substrate and prevent air seeping out from the substrate, which can cause blistering.

Floor Levelling Solutions for Wood Flooring

A dry, even and strong base substrate/screed is the prerequisite for any floor finishes. If the substrate needs to be repaired, patched or levelled, there are several factors to be considered:

  • Base substrate strength
  • Cleaning
  • Dry base substrate
  • Curing and drying times
  • Weak and ‘springy/flexing’ subfloors
Wood Floor Adhesives

The adhesive must hold the wood in place, connect it to the underlying screed and transfer stress originating from the natural expansion and contraction of the wood to the generally rigid screed. The undesired but natural movement of the wood can become visible in cupping, joint formation, or in extreme situations failure of the adhesive or screed.
There are three classes of wood floor bonding adhesives:

  • Hard adhesives
  • Hard-elastic adhesives
  • Elastic adhesives

Our SikaBond® adhesive line strongly bonds wood to most substrates, including concrete, plywood and levelling or patch underlayments that have been properly prepared.


Wood is the only raw material that is renewable, biodegradable, recyclable, durable, versatile, energy efficient and extremely beautiful. There are generally two classes of wood floors, those produced with solid wood and those with engineered wood. For whatever wood you are using, there is a SikaBond® wood floor adhesive that meets the requirements for a durably, sustainably bonded connection with the screed.

Varnishes and Oils

Solid wood floors are generally installed unfinished, in contrast to the engineered wood systems that are installed factory finished. Therefore, after laying the solid wood floor and allowing time for the selected adhesive to cure, the wood is sanded and finished in a series of steps.

Sika Synteko® wood floor finishing systems are designed for the finishing, oiling, cleaning and maintenance of solid wood floors. They were created for quality-minded wood floor contractors, who appreciate their features of easy application, extended durability, and the natural appearance of the finished wooden floor.
