With various geometric compositions and the natural resistance of wood, they became a symbol of sophistication in the 1950s and 1960s, remaining to this day as a valued choice in residences and commercial spaces. However, over the years, it is common for this type of flooring to show wear, stains, unevenness or even loose pieces. Restoring a taco floor not only restores the original beauty of the wood but also prolongs its lifespan, avoiding complete replacement with new coverings. The process requires attention to technical details, from the evaluation of the overall condition to the final finish. Below, you will find the main steps to recover the shine and elegance of your floor.
Before starting the restoration, the first step is to analyze the conditions of the floor. This evaluation determines which techniques will be necessary and whether some pieces will need to be replaced. Check for loose or hollow tacos, presence of termites, deep stains, or broken parts. In cases of severe pest attacks or structural damage, it may be necessary to consult a specialized professional to prevent the problem from spreading. Another important point is to identify unevenness between the pieces. Often, the tacos loosen over time due to the natural movement of the wood. These flaws need to be corrected to ensure not only aesthetics but also the safety and comfort of the projects. A well-made diagnosis at this stage avoids rework in the following phases.
With the floor inspected and basic repairs done, scraping begins. This process is crucial to remove old layers of varnish, accumulated dirt, and small imperfections.
The scraping can be done with specific machines known as sanders, which ensure greater uniformity in the result. Depending on the wear, several passes are needed, starting with coarser sandpapers and finishing with finer ones. In addition to removing residues, scraping also serves to level the tacos. This leveling is crucial for the floor to be uniform and without bumps between the pieces. After this step, the project already gains a renewed appearance, revealing the color and natural pattern of the wood.
During scraping, it is common to identify pieces that do not adhere well to the subfloor or that are damaged. In these cases, replacement is essential.
The tip is to use tacos of the same wood species and with compatible dimensions to maintain the aesthetic uniformity of the set. Often, specialized stores offer reclaimed demolition pieces, which can facilitate the combination of shades. The gluing of the tacos should be done with suitable adhesives for wood. The subfloor needs to be clean, dry, and leveled to ensure adhesion. After replacement, it is recommended to wait the drying time indicated by the glue manufacturer before proceeding to the finishing. This care ensures greater durability and prevents the pieces from loosening again.
The finishing is the stage that enhances all the restoration work. After scraping and replacing the pieces, a sealant layer is applied to prepare the wood, followed by varnish or resin.
The varnish can be matte, satin, or glossy, according to the aesthetic proposal of the project. The resin offers greater resistance to scratches and is recommended for areas of higher traffic. In addition, it is possible to choose a finish with peroba oil or products based on natural oils, which enhance the wood's texture and provide a more rustic look. Regardless of the choice, application should be done uniformly, respecting drying times between coats.
To keep the taco floor looking beautiful for longer, some simple care is essential: avoid dragging furniture without protection, keep the cleaning with a slightly damp cloth, and reapply varnish or oil layers every few years, as needed. This way, the floor retains its charm for decades. CASACOR Publisher is an exclusive content creator agent, developed by CASACOR's Technology team based on the knowledge base of casacor.com.br.
