1. Selection of the mixture for a floor
The secret to successful selection of a mixture for floor screed is recommended that you look on the back side of the bag, there's the small print composition and grain size of the mixture is indicated.If the size of the dry mixture fraction greater than 1.5 milli
Classical Self-leveling should provide close to 10 mm of the finished layer.If the manufacturer declares a layer of the mixture to 30 millimeters, you can safely rely on the effect samorastekaniya mixture.If this parameter is 50 - 80 mm, it is "well-kept" composition, less fluid, thick consistency like sour cream, which should be to level of beacons usual rule.
When buying a mixture for floor leveling never forget the period of manufacturing of the product.Here you need to do as food, choose only fresh bags.Keep in mind that actions often proposed stale goods.So do not hesitate to watch the production date on each package.Shelf life of the mixture when properly stored up to 6 - 12 months.
To calculate the mixture for floor screed is necessary to make some calculations.When the layer thickness of one millimeter away 2,2 kilograms of dry mixture per 1 square meter.The index 2.2 is multiplied by the average value of the differential gender.To calculate this number, measure the height of the depression and the surface relative to zero, subtract from the larger and smaller divide by 2.
resulting value multiply by 2.2 to get the approximate consumption for floor screed mixture per square meter.Then multiply this figure by the number of square meters of your room.If you need to know how much you need the bags for floor screed mixture, the resulting figure should be in kilograms divided by the mass of a mixture of 1 bag.
2. Tools Required
to manufacture floor screed you will need:
- measuring container to measure the dose of water;
- capacity with a flat bottom to mix the solution;
- Low-speed drill for good mixing of the solution;
- spiked roller to remove air bubbles after application to the base plate;
- squeegee with adjustable height to distribute the solution;
- Needle soles movement.
3. Preparation of the base
Before working on the application of this solution is recommended to close windows and doors in the room.The room temperature and the substrate must be 5 - 25 degrees above zero.Humidity should be no more than 90%.The air inside the room should not move above the floor in the process of work and 24 hours after its completion.
first step is to check the condition of the base, or rather its strength with a hammer or device Kashkarova Ri-Ri.Thoroughly clean the floor from dust and debris.The base should also be vacuumed.All cracks and chips that infringe maintain the integrity of the base should be carefully embroider, clean and caulk a repair mixture.Ideally
recommended to cover the surface of the primer layer composition, whereby reduced water absorption of the mixture and improve adhesion with the base a base solution.The primer is made to apply a thin layer, avoiding the formation of puddles.After drying the primer composition, check the water resistance of the base floor.For this is poured onto the primed surface screed little water and visually determine the change in quantity.If the basis of absorbed all the water, it is recommended to apply a first coat again.
If you are balancing the weaker sex, then you should definitely install a reinforcing mesh, which will strengthen its structure.When using a glass fiber mesh layer thickness must be not less than 1 centimeter.The mesh is attached to the base dot.If it is not stuck well enough, it can float to the surface.
Then you can do the installation of the flashing profiles.Reiki set so that they coincide with the top marks that are marked on the wall.By the way, experts do not use such profiles as without them able to display the horizontal.But if you first make a tie, better still not to give up on the beacon to improve the quality of floor leveling.
4. Preparation of the solution
To start pour water into the container and add the cooked mixture is ready for floor screed, stirring constantly mass.The water that is needed to dilute the composition should not be too hot, otherwise the mixture will not have time to spread and there will be an uneven surface.If large areas require a large amount of the solution, which will not work by hand mix.Therefore, the mass mix with water using a powerful drill with a special nozzle.
At this stage, it is recommended to comply strictly with the recommendations of the manufacturer, because the excessive amount of water provokes a bundle of material, foam covering, improper hardening and loss of strength characteristics.Operated at room temperature, at lower rates may be some problems.
5. Plans screed
There are such schemes floor leveling with the help of dry mixes:
- in a dry place with a solid foundation using the contact floor.When such a scheme to provide a rigid connection coupler made of self-leveling compounds, with the rough ground.
- If the base is sometimes exposed to moisture or difficult to achieve high adhesion to a leveling layer is applied on the floor separation layer.In this case, the leveling compound taken applied over the separation layer created from a polyethylene film having a thickness of 0.2 millimeters.This film is laid with overlapping and calling on the wall.
- If you plan to build an additional sound or heat insulation, used for leveling the surface of the insulating layer.First, on the basis of dry insulating mats are placed so that they adhered to each other tightly, and along the walls - expanded polystyrene strips for expansion joints.On top of a plastic film with a stop at the walls, and then a leveling layer.
- When making leveling floor in underfloor heating system fill mortar for floor screed is carried out in two stages to prevent the surfacing of cables and pipes.Before laying the mixture when water heating pipe filled with water, and then depositing a first planarization layer to the top edge of the equipment.After setting the first layer is applied a second layer above the edge equipment 25 millimeters.The system can include at 7 days after casting the solution, gradually increasing the temperature of 3-5 degrees per day.
6. The process of filling mixture
Ready to pour the mixture onto the prepared base, starting with the far wall of the entrance and filling all the irregularities to the lighthouse.It is recommended to fill all at once, working very quickly.This avoids the process of avoiding the top edge of the previous strip and make a perfectly flat surface.
If you intend to fill a large area, the mixture is poured on the draft floor strips parallel to the wall of 30-40 centimeters, performing pouring through one.The gaps are filled when dry previous band.Joints coupling walls and filled with sealant and filling "argument" with the help of a wide steel trowel.
When grouting machine is supplied with the mixing and feeding units with a speed of 6 - 120 liters per minute, depending on the type of machine.Before the procedure is recommended to check the mixture to flow and pour a small amount on the base substrate.After stabilization of the masses should measure the diameter of the spot and compared with parameters specified by the manufacturer - the amount of the mixture for floor screed and the corresponding diameter.
Remember that you can not in the course of applying the solution to go beyond the thickness of which is characteristic of a particular type of mixture for floor screed.When pouring thinner layers would be impossible to keep water that is required for solidification of the solution.If the screed is exceeded in thickness, then grabbed layer, so these layers is recommended to stack several times.
7. Finishing work
After grout trowel or rule it completely leveled.Using spiked roller or brush with long bristles solid removed bubbles that occur in the material.It is advisable first few days after leveling the floor to adhere to temperature, which is specified by the manufacturer, to avoid drafts and direct sunlight.
Time during which the mixture is completely dry, will depend on the humidity and temperature, as well as the index of the thickness of the screed.Accelerate such a process without expert advice is not worth it, because the manufacturers are not provided for curing the dry mixture for floor leveling in the non-normative terms.Failure to process conditions and high moisture content based slow the drying process.
When you can walk on the ground, on the surface of expansion joints should be made that the pre-marked on the wall.To do this, cut the flattened layer using an angle grinder.Thereafter, expansion joints must be filled with a special elastic material.
Before filling topcoat should pay attention to the moisture level of the alignment layer, it must be the same as in the materials used.Following all of the above described recommendations on the use of fast drying floor screed mixture and correctly observing the processes, you get high-quality, perfectly smooth base for the future installation of flooring.
