Since you are reading this article, it means that you have already chosen modular parquet to your taste, that is, you have chosen a color, texture , material and dimensions. And of course you are thinking about how to lay this parquet? Below we will describe how to install parquet according to the rules.
Varieties of subfloors for parquet
1. Cement-sand screed
The base must be dry, the moisture content should be approximately 4%. Also, the base should not be soft, there should be no delamination or deformation on it.
Evenness differences are allowed not more than 2 mm of area on two meters of the base.
2. Reinforced concrete panels
Such a base is not suitable for laying parquet, because, in fact, it is a "bare" floor. First, such a base must be leveled better with a cement-sand screed or using a lag.
This is a well-made wooden floor. An old worn-out floor is no longer aesthetic, but it is often used as a solid base for parquet. But the floor must have sufficient height and the quality of the floor must be good.
Wooden logs are bars with a section from 30 * 30 to 120 * 120 mm.
Lags are laid with a distance of 300 - 400 mm obliquely, depending on the direction of laying the parquet.
Then the logs are leveled, glued and attached with dowels for reliability. As a result, we get a honeycomb structure. Then insulation or expanded clay is placed in the cells. Then plywood is attached to the wooden logs with an offset. Then plywood is laid on the first plywood layer in a checkerboard pattern with respect to the first plywood layer.
After all these manipulations, parquet is attached to the structure.
Before using the old wooden floor as a base, it must be checked, all defects removed. The wooden base should have a moisture content of no more than 12%.
1. Priming the base
Before priming the base, you need to clean the screed from debris, glue, dust.
A primer can be applied on top of the screed. The best primer is considered to be a two-component one, it helps to improve adhesion, penetrates deep into the porous structure of the screed and promotes waterproofing.
2. Laying plywood
The thickness of the plywood base should be 2/3 of the thickness of the plywood plank. The thickness of the plywood to be laid depends on the thickness of the selected parquet.
The plywood is attached to the concrete base using a dowel - nails and glue, the laying is done with an offset of the seams. A gap of about 5-10 mm is maintained between the plywood sheets, the gap near the walls is at least 10-15 mm.
Glue is applied using a spatula with notches, with their help, the glue consumption is regulated. In order for the plywood to adhere well to the concrete base, it is necessary to use glue with a low water content.Plywood is attached with self-tapping screws, so to speak, they are recessed in plywood.
3. Choosing the type of parquet installation
Before starting work, make sure that the conditions in the room meet all the requirements. In the event that there are deviations from the norm, then it is necessary to eliminate them. Before installing modular parquet, the parquet modules must be adapted to the room where they are planned to be installed. Packs with parquet are left for 3 - 5 days in whole packages in the room where they will be laid.
The packs are opened only when they begin to lay the parquet, the parquet is attached with self-tapping screws and glue.
1. Laying uncoated parquet
Modular parquet is supplied from the warehouse in the form of assembled squares from an array, but which are not fastened together. They are connected to each other with ordinary adhesive tape. At the assembly site, the parquet modules are glued and sanded.
If cracks are found, they are putty, then sanded, primed and covered with oil or varnish in the finish.
When installing parquet, use water-based or solvent-based adhesive. Two-component glue is very rarely used. When laying the parquet, make sure that the gap between the wall and the edge of the parquet module is observed.
Laying ready-made modular parquet
When laying the finished parquet, use only two-component glue, which is applied to the plywood. When laying, it is also necessary to monitor the gap between the wall and the parquet. Parquet modules are fastened together using dowels. The new floor can be used two or three days after it is completely dry.
After reading the article, you probably understood that laying parquet is not an easy task and, perhaps, you will not be able to lay modular parquet.
Then we advise you to entrust the installation to professional workers, because they have a small chance of making a mistake when installing. You yourself can make a bunch of mistakes, but there will be no way to fix these mistakes. So before starting work, think well and make the right decision.
We wish you good luck in your endeavors!
