Polishing the parquet with his hands
The contents
Quality hardwood flooring is a reliable and durable coating, provided that the owners of the apartment are constantly monitoring his condition. But even with all the rules for the use of this material sooner or later it loses its original form and requires grinding.
How to determine the need for polishing ↑
Before you decide to change the flooring, you should carefully look at its condition and to consider whether grinding or the damage is so strong that it will need a new material. It can be defined according to several characteristics. Grinding will not help if:
- The cracks between the planks of the flooring is 5 mm. In this case, the floor resembles a mesh of wooden elements.
- Happened swelling due to wetting. When such defects change is impossible.
- The flooring was badly worn. If from the top surface to the connecting element remains at least 5 mm, then polishing will not help.
- There are deep deformations.
- The floor was constantly wet from below. Hardwood floor sanding is meaningless, since it is necessary to change completely covering and securely seal.
- In the room there was mold or rot.
Equipment for sanding parquet flooring ↑
Before polishing the old parquet floor was made manually, but is time-consuming and lengthy process, so you should use special equipment. The process consists of several stages, each of which needs a specific device:
Machine drum-type. It is designed to level the floor and need to remove visible and deep deformation of the surface.
Surface grinding machine. Such devices are one – and three-disk and are intended for surface preparation prior to tinting or application of the lacquer. These devices are used for finish sanding.
«Boot». Such grinding machines are designed for work in tight spaces where large devices to make the flooring fails.
Industrial vacuum cleaner. Such a device is necessary to remove all the small particles left after sanding. Only after the dust is removed, you can start applying the varnish.
Instead of a device for sanding corners is fine the grinder with a special attachment. You should also stock up on a few rolls of sandpaper of different types:
- P40, designed for rough treatment,
- P80, used for grinding.
Sanding of plywood ↑
One of the best reasons for flooring is plywood that is laid on a concrete floor or joists of wood. The second method is more expensive and complex, but at the same time has the advantages of:
- cabling under floor communications,
- installation of sound and thermal insulation layer,
- flat floor surface.
But before laying the floor covering, is made by grinding of plywood under flooring. This is necessary in order to remove all irregularities that exist at the joints between sheets. Is this with machine drum, then the surface thoroughly cleaned of dust.
What is different from sanding grinding ↑
Early in the term scraping was called the removal part of the surface of the wooden floor with a special hand tool. But with the advent of machines this procedure have ceased to apply. In addition, it is not suitable for modern types of flooring, as it has a smaller thickness.
Grinding allows you to save the surface for a long time, as opposed to simply removing a piece of wood. Before the distribution of special devices this operation was performed manually with the help of attached to the leg of sandpaper. But this activity is very time consuming and does not allow to make the floor perfectly smooth. That is why is only professional hardwood floor sanding.
The main stages of updates floor ↑
Grinding takes place in several stages:
- Rough machining. It is made by drum-type machine, resulting in removal of all significant irregularities and the old cover.
- Sealing of cracks and crevices.
- Fine sanding. In this phase, is cleaned from small surface flaws.
- Working with hard-to-reach places. It is performed using a grinder or a specialized grinding machine.
- The removal of surface dust and debris.
- Applying nail Polish. Covering the floor for the first time, you should wait for complete drying of the composition, and then to produce intermediate sanding, and then use the composition again.
If all described operations are conducted thoroughly and professionally, then the second floor restoration may require only 10 or 15 years.
The choice of varnish ↑
One of the most important factors when choosing the paint is the load on the parquet floor. If the attendance of a large room, you should use a water-repellent compositions, intended for floors in public areas. All such compositions are distinguished by:
- properties,
- composition,
- appearance,
- the degree of gloss,
- resistance to loads.
But the choice is usually determined by the composition or properties. Most commonly used sealer, which is applied before final coating and enhances its adhesion to the Board. Drying such compositions quickly enough and therefore the repair process is not delayed for a long time. For best results, you need to choose products from one manufacturer, which is associated with a better grip.
One of the commonly used varnish becomes water soluble composition. Its cost is small, and the properties allow the use in different conditions. One of the advantages of such varnishes is the lack of a strong smell, so repair is possible even in the presence of people in the apartment. They are resistant to heat, making possible their use in areas where there is a probability of fire of objects.
Also popular are the polyurethane mixture, which possess high durability and can therefore be used for flooring in such rooms as kitchen, living room. The second advantage is the quick drying varnish, which allows to reduce the repair time. But it is worth remembering that during application it is necessary to protect the floor from moisture, otherwise you will see the emergence of irregularities. One of the main advantages is the feature of the coating, which eliminates the need for primer.
There are also varnishes oil-based resins obtained from natural raw materials. They are deep enough to penetrate into the wood and securely fixed to it, but it does not form a solid film, therefore, for flooring this type of compounds is not suitable.
One of the most stable lacquers is formaldehyde. It has the following properties:
- good adhesion to floors,
- no need to use primer,
- immunity to temperature changes.
In addition, for this varnish does not need to choose the right painting tools.
Polish ↑
Apply the varnish can be by brush, roller or spray gun, but the second method is the most convenient and simple, therefore it is chosen by many apartment owners and builders. When buying a composition for the surface you should carefully examine its characteristics, as some coatings require a primer. To avoid mistakes, consult with the seller.
If priming is necessary, its application takes place in the same manner as the coating of the floor Polish composition is distributed evenly over the floor with a roller. Then you have to wait until the surface is completely dry and only then continue.
It is worth remembering that the application of the composition on the surface is only possible in one direction. After the first strip of varnish of the second is superimposed on it, about one-fourth of the. So varnish is produced as long as it does not cover the entire surface of the room. After that you should wait for complete drying of the flooring.
Before you apply a second coat to check the grinding fine-grained sandpaper. So on the surface no dust, it is washed with warm water without using detergent. The second layer of varnish may be applied in the same direction as the first, or perpendicular to.
