Features of using plywood for laying quartz vinyl

Plywood is a common material for flooring projects and works well with quartz vinyl. This mixture provides a solid base for your vinyl, guaranteeing a glossy, long-lasting finish. Plywood is a practical choice for a variety of construction and renovation projects because it is strong and simple to work with.

There are a few things you should consider carefully when installing quartz vinyl over plywood. The plywood must first be appropriately prepared. This entails making sure it is dry, clean, and level. Before installation, any bumps or gaps in the plywood must be fixed because any flaws will show through the vinyl.

An additional crucial factor is the plywood’s thickness. The type of vinyl and the state of the subfloor will determine the appropriate thickness. In general, a thicker plywood will offer more stability and lessen the possibility that the vinyl will feel squishy or unstable underfoot.

All things considered, laying quartz vinyl on plywood can be a wise and effective decision. You can create a stunning and long-lasting floor that will improve the appearance and feel of any area with the right planning and execution.

Can I use?

An underlay is a layer that is placed between the screed and the finishing floor covering. To do this, a variety of man-made and natural materials are employed in order to boost strength, enhance performance, and create a thermal insulation layer.

Additionally, plywood will be utilized as a substrate; however, for this use, the sheet joints are puttied appropriately. Not only is plywood backing feasible, but it also needs to be installed in a way that allows it to serve key purposes:

• dampened noise, since there are no floor surfaces with perfect evenness; when someone steps on the floor, a creaking sound is heard because air accumulates under the covering due to small irregularities;
• a product made with LVT technology has a rough surface, which will be hidden by the substrate; without plywood, over time, an effect will appear with the depiction of the floor relief;
• sheet material provides comfortable thermal insulation.

Smooth boards used for the subfloor will eventually start to warp from outside influences, which will cause the quartz vinyl locks to break. Because plywood satisfies every requirement for serving as a base for quartz vinyl floors, it will rectify the situation.

As long as at least one side has been polished after expert laying has been completed. Use only premium plywood for adhesive flooring, making sure to level, fix, and putty the joints.

Purposes of application

To accomplish specific goals, moisture-resistant plywood will be used; underneath the quartz vinyl, there will be a base:

• clean;
• durable;
• dry;
• stable;
• smooth.

The condition of the base determines how to prepare it for quartz vinyl. Plywood must be laid for the finishing coat on a wooden floor, underneath the interlocking tiles and the adhesive. Self-tapping screws are used to fasten the sheet material, and each cap is puttyed, sanded, and recessed. Wooden backing:

• corrects the base, compensates for minor unevenness of the floor;
• eliminates squeaks and noises;
• serves as a heat insulator.

Moisture-resistant material will boost resistance to mechanical stress, add strength, and guard against moisture seeping into the surface layer. Up to 12% of moisture is permitted in plywood sheets. If not, mold and other harmful fungal growths will develop.

Requirements for the base for installation

An uneven plane cannot be leveled with a plywood sheet; the substrate offers no additional performance benefits. A flat base is one that is devoid of lumps and bruises. On a smooth surface, differences shouldn’t be greater than 2 mm/m2. Irregularities can be found with the aid of building level and rules.

When they say that a surface must be monolithic, they mean that there must be no voids or fractures. Even beneath moisture-resistant plywood, the base needs to be dry; an electronic moisture meter can be used to measure the humidity.

On a firm foundation that doesn’t crumble or peel, high-quality material installation is achievable. What counts is how hard the subfloor is so that loads can be applied gradually.

When force loads from both the horizontal and vertical directions are applied to the surface, it means that the base is stable and does not sag or sway.

Plywood can provide a level and sturdy base for quartz vinyl flooring installation, guaranteeing a smooth and long-lasting finish. Plywood offers a sturdy surface that extends the life and functionality of the flooring and helps stop vinyl from moving or warping. This method works particularly well for subfloors that are damaged or uneven.

Material requirements

Quartz vinyl is often used to cover plywood substrates because it satisfies the following requirements:

• has sufficient density, elasticity, resilience, and is able to withstand vertical load forces without deformation;
• has optimal dimensions in terms of thickness;
• does not collapse under point loads.

The type of sheet building material that the manufacturer designates on the label is something you should be aware of.

The state of the front surface polishing in the production areas determines the grade:

• NSh – unsanded plywood;
• Ш1 – polished on one side;
• Ш2 – material subjected to double-sided grinding.

For quartz vinyl flooring, 2/4 grade plywood with one or both sides sanded is recommended. The front surface’s acceptable grade is shown by the first digit, and the reverse side’s fourth grade is reflected by the second. The sheet is labeled FSF, which indicates its moisture resistance. "E" stands for elite-grade, high-grade material.

Since LVT flooring is not rigid, a sturdy base is required. Select a thick 15 mm plywood for the backing when installing it on joists. The sheet is placed with a thickness of 10 to 12 mm if installation is to be done on a concrete screed.

The material’s thickness is a crucial factor because self-tapping screws are used as fasteners and are screwed to the sheet’s depth. A thin sheet will allow the fastener to push through it and lose its ability to hold under loads caused by deformation.

During operation, thick plywood resists external influences, humidity, and temperature changes while remaining stable.

Criterias of choice

Plywood categorized as follows based on its areas of use:

• construction;
• packaging;
• industrial;
• furniture.

Items bearing the FSF label have improved water-repellent qualities because they have veneer layers that are adhered to one another perpendicularly with a unique glue. Production technology has given the sheet resistance to deformation and stiffness.

Wood veneer is used in the production process as a raw material for construction work.

• coniferous – with increased resistance to decay, but with a loose structure, included in the inner layers;
• deciduous – high strength indicators, used in front layers.

Plywood can have the same, distinct, or even elite grade on each side. For substrates, an ideal appearance is not necessary. Strong gluing despite a poor surface on the back of grade 4. The second category can be processed using as a substrate for minor flaws.

Under adhesive

With adhesive fixation, you can set up a sturdy and dependable floor because the material maintains its shape even in the face of temperature fluctuations. However, this does not remove the prerequisites for the base’s condition with regard to:

• hardness;
• solidity;
• evenness and acceptable humidity indicators.

A plywood substrate will make the base stronger and more level. A particular type of adhesive is used to attach the finishing coating to the plywood. Since LVT is a flexible material, the type of glue used during installation depends on the base. Instead of applying adhesive to the tile, 2 m 2 of plywood is covered with it.

A plywood substrate FSF grade 2/4 with one-sided grinding Ψ1 would be the ideal choice.

Under the lock

Underlayment similar to adhesive fixation for floor coverings with interlocking slab fastening. However, there are more stringent requirements for the base. When plates are joined with locks, there are minute spaces where foreign particles, such as dust or moisture, may seep through. This kind of quartz vinyl has the benefit of being easily maintained.

You can always quickly replace the fragment if the slab isn’t working properly or if the locking connection is broken. Plywood with enhanced moisture resistance (FSF) is used as a substrate; a grade of at least 2/4 and Sh1 is adequate, with one side sanded. The base’s rigidity is a crucial factor to consider when selecting a substrate. The lock will come out of the lock pit and need to be disassembled if it bends when loads are applied.

The floor will be covered whether the quartz vinyl is adhesive or interlocking. When selecting sheet material, the following factors are mostly considered:

• type of base – on a concrete screed, the thermal conductivity is increased with a sheet thickness of at least 15 mm, a rough wooden floor or joists are sheathed with 10-12 mm plywood;
• purpose of the premises;
• thickness of the subfloor, plywood prolongs its service life and protects it from sagging.

The life of the floor covering can be extended by selecting the proper kind of plywood underlay. The density and rigidity of plywood is sufficient to cushion even the softest and most flexible LVT quartz vinyl.

Installation rules

When plywood is installed over joists, there should be no more than 0.6 m of space between them. The plywood is secured with a 15 mm thick layer. The substrate has different dimensions; it is 6 m long and 3 m wide, with a thin sheet that is 3 mm thick. Any horizontal base can be leveled by covering it with plywood and selecting the appropriate size:

• for wood logs – 1525x1525x15 (mm.);
• in multi-storey standard buildings, the base is leveled with plywood 1220×2440 (mm.);
• in studio living spaces, a sheet of 500×3000 (mm) is suitable.).

The plywood backing’s thickness is chosen based on the loads and screed level. Thick sheets are required if heavy loads will be placed on the floor. If the joist pitch is within 0.4 meters, a thickness of 10 mm is appropriate in residential buildings. Quartz vinyl does not result in a noticeable increase in mass, and the final cladding likewise has a static load.

When installing plywood on a concrete foundation, abide by these basic guidelines:

• remove debris, remove greasy stains and traces of dyes;
• level the surface with cement mortar;
• get rid of cracks, chips and potholes with a thin layer of putty;
• check the permissible humidity within 5%;
• lay the sheets, level the differences between them by grinding;
• dust the surface;
• if there are any defects, they are eliminated with putty.

Move on to the following step after completing the preparatory work in accordance with the created installation scheme:

• mark the floor, along which the plywood is fixed with screws, the axial layout will also be useful for installing quartz vinyl;
• the joints of the sheets and the recessed heads of the fasteners are puttied;
• areas with finishing are sanded, planes are leveled.

It should be mentioned that quartz vinyl is adhered to plywood using contact or dispersion adhesive when installing adhesive tiles. When there is a locking connection, the substrate, base, or subfloor are not connected to the fastening; it is only done between the components.

Calculation of the required quantity

I use calculators offered by different services to determine the quantity of plywood required for a substrate beneath a quartz vinyl coating. First, you must determine the sheet’s size:

• 1220×1220;
• 1525×1220;
• 1525×1525;
• 1830×1525;
• 2440×1220.

Must be aware of:

• room area;
• distance between joists or dimensions of solid base.

Independent calculations for a square or rectangular room won’t be difficult because basic arithmetic formulas are applied. To determine the size of the sheet and the room is sufficient. Setting up a substrate for quartz vinyl can be calculated quite easily.

S2 is equal to H x D = 4000 x 3000 (mm) = 12 m^2, rounded up from S1=h x n = 2440 x 1220 (mm.) = 2.976 (m2) or 3 m2. where S1=12, F=S2, and 3 = 4.

1. S1 – area of ​​plywood sheet
2. S2 – room area
3. h – sheet length
4. n – plywood width
5. H – room length
6. D – room width
7. F – the number of sheets of a certain type that will be required for the substrate.

You will have to put in a lot of effort to figure out the total floor surface area if the room has intricate structural shapes.

Divide the floor into pieces with regular geometric shapes to make the calculation easier.

Materials and tools

A typical set of instruments and supplies is needed to lay plywood as a substrate beneath quartz:

• pencil with measuring tape;
• putty with a spatula;
• rags;
• primer;
• roller;
• sandpaper for sanding;
• screwdriver for screwing in fasteners;
• vacuum cleaner to remove clogging from surfaces.

If you must use adhesive quartz vinyl, a primer is required for improved adhesion. It is advised to sand self-tapping screw heads treated with putty using fine-grain sandpaper P100–P150.

Installation instructions

Use dependable fasteners and premium materials when selecting plywood backing. plywood affixed to the foundation:

• self-tapping screws;
• glue;
• combined method.

Plywood installation should be done in the following order, per instructions:

1. Stage No. 1. Preparatory work. They collect tools, take measurements, calculate material consumption, purchase plywood with quartz vinyl.
2. Stage No. 2. Prepare the base, check the concrete screed for moisture, remove debris, get rid of chips and cracks.
3. Stage No. 3.Perform markings for laying sheets. Plywood is attached to a flat wooden base or joists with self-tapping screws. If the base is concrete, sheets are glued, choose a substrate that is not large in size. The combined mounting method is suitable for any base, the sheet is glued and screwed with self -tapping screws for additional reliability.
4. Help. It should be taken into account that high-grade plywood has a stable thickness, this levels out differences when joining sheets, the sanded side improves adhesive adhesion.

Errors and difficulties

When plywood underlayment is utilized to level surfaces and solve every issue, base condition, cracks, and unevenness are ignored. Deformation of the subfloor and finishing may result from this.

Even experts in floor covering installation can make mistakes when it comes to positioning plywood:

• on an uneven, dirty base;
• on a wet screed;
• the sheets are not tightly joined;
• the screw heads are not deepened;
• the joints and fasteners are not putty.

Specialists create instructions based on analysis, information from experts, and the outcomes of construction projects, specifically adding more gaskets to the floor covering.

The floor covering serves as the apartment’s front face. Violations can be challenging to fix; you must fully remove the quartz vinyl, remove the underlay, and redo the work following skilled finishers’ instructions.

Advantages and disadvantages

There are benefits to using a plywood layer between the subfloor and the finishing floor covering.

• minimum humidity level;
• protects the screed from deformation, absorbs and dampens mechanical stress;
• the product is made from environmentally friendly veneer and contains no harmful impurities;
• simple installation;
• large selection of products by brands and varieties.

Minuses:

• there is no great resistance to temperature changes;
• Requires additional processing for moisture resistance.

From its long history of use as a robust and sustainable natural building material, plywood has seen significant demand over time.

How to properly lay quartz vinyl tiles on top?

Installation features need to be considered in order for plywood to serve the purposes intended for it as a substrate for quartz vinyl:

1. Fasten plywood only to a dry screed. You can check the readiness of the base by covering it with film. If the screed has not dried, condensation will appear on the inner surface.
2. The laying of the substrate is carried out after completion of all repair work on the walls and ceiling, so that loads and moisture do not act.
3. Check the humidity level in the environment; the humidity in the room should not be higher than 60%.

The plywood backing and base of the flooring determine its quality.

Average costs for materials and labor

Numerous substrates are available for purchase, specifically multilayer plywood, for quartz vinyl.

1. FSF 1220x2440x12, grade 2/4 with humidity 4-11%, weight of one sheet 15 kg, packaging costs 2360 rubles. Pack contains 4 sheets.
2. FSF 1220x2440x18, grade 2/4 price of package with 4 sheets – 3100 rub.
3. FSF 1220x2440x15, grade 3/4 packaging costs 2400 rubles, it contains 4 sheets.

Finishers’ assessments of their work vary by region. Installation under quartz vinyl can be ordered in the Krasnodar region for roughly 200 rubles per square meter.

Like in any other part of Russia, craftsmen in Moscow attempt to reach a price agreement with their clients. Prices exceeding 300 rubles per square meter were not noticed, even in upscale homes and apartments.
