Laying flooring on the joists and screed: how to prepare the ground

All versions of the subfloor in the living areas, in essence, boil down to two designs – joists and concrete screed. In this article we will explain how to prepare such grounds for laying floor coverings.

Preparation of the concrete screed

Concrete screed provides a sufficiently smooth and hard surface for the floor covering. If it is done well, it does not need to align. However, to put a floor covering on concrete just can not – in any case, the desired substrate

Laying laminate flooring

Укладка ламината

Laminate can be laid at the base with a maximum height difference of 2 mm per 1 m of the surface. However, even if your tie has a little differential, laying it on concrete is impossible, because the screed beneath it will “crunch”. In addition, residual moisture in concrete is harmful to the lower layer of the laminate.

Before laying the underlay, you must make sure that the concrete has dried. For this we need to put on the tie sheet of polyethylene with a size of 1×1 m or more and leave it on overnight. In the morning if it on the surface of the polyethylene will not appear condensation drops, the coupler can be considered ready for further work.

The substrate under the laminate consists of two layers of polyethylene film, actually the substrate, foam or cork. A polyethylene film is laid with an overlap of not less than 200 mm and glue the seams with tape. The edges of the film must go to the wall for a few cm – they all Rayno will be covered by baseboard. put on top of the film substrate. Softer foam backing, they are well compensate for uneven floors. The substrate of the tube harder, but provide more effective sound insulation and have longer service life. On top of the substrate you can put laminate.

If the elevation of the screed exceeds 2 mm per 2 metres, it is possible to compensate for sheets of plywood. The substrate and residential premises, you can only use plywood FC, because it does not emit. In the back rooms can be placed and laminated WBP plywood, but it makes no sense, because it is more expensive.

Укладка напольных покрытий

Plywood should not be very thick – 12 mm is enough. You can take the cheap, grade 3/4 or 4/4. Sheet shaping them into squares with sides about 50 cm, to reduce internal stresses in the layers. Then these squares are glued to the concrete any construction glue and (very important) bolted with screws.

Please note: between the walls and the adjacent edges of the plywood should be a gap of a width not less than 1 cm Between the edges of the leaves, we should leave a gap width of about 4 mm and subsequently to seal its elastic putty plywood on Top of stacked plastic film, on it the substrate and then laminate.

Laying floor Board

Укладка половой доски

If the screed is flat and batten has a thickness of 27 mm or more, it can be installed on the foam substrate of the laminate, it will be enough. With a larger altitude difference or a small thickness of the Board will need a layer of plywood 12 mm thick.

Laying linoleum

Укладка линолеума

Linoleum should be put on a substrate of plywood FC 12…15 mm. the plywood to be cut into squares – the less irregularities will be the basis on which we will lay the linoleum, the less chance to push and break it. Plywood is glued with glue, then fasten with screws, and not only on the perimeter, but across the square in increments of no more than 25 cm When it is necessary to watch that the head screws were recessed into the plywood, but not much. All joints between sheets should definitely seal with an elastic putty.

Preparation of the floor joists

Floor joists are simple, cheap and therefore popular. Logs make it easy to insulate it – you just lay mineral wool insulation between the boards. The lack of it has only one lag on top of the need to create a smooth, durable and hard coating that will resist dynamic loads

Insulation and vapor barrier

Утепление и пароизоляция

If the overlap with which we work, is located between heated and unheated rooms (e.g., first floor and cold, hiding under it), you need to protect mineral wool vapor barrier which is placed from the heated space. In the case of floors, the first floor a vapor barrier is placed over the lag of the floor, between which is the insulation. The joints between the strips of vapor barrier film have to be taped.

Vapor barrier is laid over the base floor. It can only consist of trim boards, only out of plywood, or of both together. Design black floor and the thickness of the layers depend on the distance between the joists, and also on how strict your requirements to the stiffness of the floor. For example, when the distance between the joists is 600 mm black floor can consist of

– one layer of plywood FC with a thickness of 21 mm the deflection is, and it is noticeable but within acceptable;
– layer of Board 25х100 mm and plywood FC 10 mm thick on top of it – almost no deflection;
– two layers of plywood with a thickness of 15 mm deflection is virtually invisible;
– one layer with a thickness of 20 mm with acceleration to 15 cm and layers of 12 mm plywood on top of the Board – the deflection will be, but very small.

Укладка на лаги

When laying on the joists to cut the plywood into squares not – the bigger the sheet the better. The gaps between the sheets and between the edges of the sheets and walls is required. A Board screwed to the joists with screws, and it is better to take not black, but yellow. The plywood is also screwed screws, and fasteners should pass through the Board and through the joists. The length must be chosen such that the joists were at least 2/3 the length of the screw.

The new interior of the old house

The Maury island in Puget Sound in Washington state is small. Most likely, you’ve never heard of him before. But, you may have heard about its larger neighbour, the island of Vashon, in which it is linked by an isthmus built by local residents in 1913. Before that the two Islands were reported only at low tide. Now they are accessible only by ferry, which practically isolates the island from the outside world and creates an oasis of peace and quiet. And it is very popular with local people, including designer Tim Pfeiffer from the Seattle company for architecture and interior design Hoedemaker Pfeiffer and his partner Matt Carvalho.

For a long time they were looking for a vacation home and finally found the building, which is the former home of shipbuilder and built in the late 19th century. It was a dilapidated building with multiple roofs, old creaking floors, peeling paint and pink plywood walls.

During the year, designers conducted an internal reconstruction of the house of 1900 square feet, removing layers of various decorative styles. To the interior was added a certain historic charm, and in an old house Dating back to 1898 has been recreated the interior of the 60-ies. Now the basis for the design are the walls lined with white cedar panel, fir floors Douglas (Douglas fir floors) and intact doors and lights.

In deference to the original owner of the house the interior is rich with sea themes. Kitchen cabinets 1950-ies emerging from the reconstruction, now painted a gray-blue color, and equipped with brass fittings. In the hallway, a round mirror resembling a window. Hanger with sturdy steel hooks, door handle and wall lamps is made in a marine style. Around the house there are many paintings depicting life in the sea and portraits of sailors, and a bathroom with charming curtains in the form of a ship signal flags.
