Ceramic Tile On Plywood

In the course of finishing, there are situations when it is necessary to combine different materials in its structure. Here is an example. The customer planned parquet throughout the apartment. Was carried out ground 'plywood on sleepers'. In the process, he (the customer) has decided to put in the hallway tiles. The decision is correct, you come off the street and the sand falls to the floor, no flooring can not survive long.

But the tiles are traditionally placed on coupler, which is almost immune to the horizontal displacement. Wood and ceramics by well behave differently during operation, plywood subject line changes can not be said about ceramics. In this scheme (this plywood timber) movement will be when the temperature and humidity conditions. For their connection required elastic adhesive. It is best suited for bonding ceramic component polyurethane parquet adhesives.

Two component – are the two components, the first – polyurethane resin, the second – hardener. Mixed before use, the lifetime varies from different manufacturers from 30 to 60 minutes. Not to be confused and do not compare with the Soviet "Epoxy" is a different product, both in composition and quality. Two-component polyurethane adhesives on the market weight, here are a few: Bona R-770, Staufen-PUK-440. Utsin MK-92, Kiilto Slim, Yurga 2K PU and many others. Initially, two-component adhesive was designed to lay solid wood and parquet from exotic wood. Movement of the array when the humidity decent, and many other exotic adhesives to glue impossible. The Germans in this piece is placed adhesive parquet on concrete screed, bypassing the plywood, we just turned this scheme to 180 degrees. It was decided to use the scheme "ceramic tile on plywood ', two-component adhesive in this case manifests itself at its best. The only disadvantage of this scheme, the impossibility of the device "warm floor". For underfloor heating is better to use a traditional scheme – tie. The scheme of laying ceramic veneers: 1. logs 50 * 70, 2. Plywood WBP 18mm, 3. waterborne parquet glue, 4. 12mm plywood WBP, 5. Glue 2-hkomponentny parquet, 6. ceramic tile. Installation Recommendations: 1. Laghi pack increments not exceeding 400 mm, double-glued plywood will provide additional rigidity to the base, plywood, one layer does not suitable for the scheme, possible fracture of ceramic tiles in the joints. 2. For 2-hkomponentnogo on plywood substrate is not required, but for wet areas can be used, for example, Bona R-410. 3. Use dispenser (spatula with slots) on 850gr/kv.m that there was no extrusion of excess glue in the seam, but if it came out, then mechanically remove the next day a piece of cake. Pros of this scheme? 1. In houses with wooden beams, it is indispensable. 2. Minimum load Compared with screed. 3. Clay pottery is not only sticks to the plywood, but also acts as gidroizolyatora. 4. The adhesive is fast enough, the possibility of walking on packed ceramics after 30 minutes. 5. Grout joints Ceramic tile can be carried out on the same day. By the way, there was a new generation of parquet glue based on modified silane. It hardens in a chemical reaction with atmospheric moisture, as well as pulling it out base. Now is not the scary hit of glue on the front side, it is removed with a cloth without a trace, which is not the case with polyurethane. I would single out the main advantage of this glue – 'high residual elasticity of the adhesive joint,' he best suited for bonding wood and ceramics.
