Due to their properties, epoxy self - leveling floors are used in manufacturing plants, retail and warehouse premises, catering establishments, garages and parking lots, in medical institutions and laboratories, schools and kindergartens, in office and residential premises as topcoats.

Types of self - leveling floors.

Depending on the purpose of the room and the requirements for the coating, self - leveling floors of different types can be used.

Thin - layer (paint) coatings (less than 1 mm) are recommended for use in dry rooms with low mechanical stress and high hygiene requirements. Service life from 2 to 4 years.

Universal coatings (1 - 3 mm) are used in rooms with enhanced decorative properties. Service life up to 10 years.

Special coatings (2 - 3.5 mm) are used in rooms with enhanced mechanical, protective and chemical properties. Service life up to 15 years.

High - strength coatings (more than 3 mm) serve up to 20 years in rooms with high loads with prolonged exposure to aggressive environments.

The use of special additives and components in the production of epoxy resins makes it possible to impart a number of additional properties to the coating: increased acid resistance, deactivation, antistatic, vapor permeability, immunity to excess water, additional strength.

Installation of epoxy floors.

 

 

 

Basic requirements for the production of work.

 

 

 

The concrete floor (hereinafter referred to as the Base) meets the requirements for the base .

Substrate temperature and air temperature: not less than + 5 ° С and not more than 25 ° С;

Material temperature + 15 ° С . . . + 20 ° С;

Relative air humidity, at the time of installation, and during the day after it is not more than 80% ;

The temperature of the Substrate differs by no more than 3 ° C from the air temperature measured at a height of 0.5 m;

When applying primer coats, the temperature of the Substrate will not rise by more than 4 ° C. Otherwise, there will be a strong change in the residual moisture content of the concrete, which will prevent the penetration of soil into the pores;

Storage and transportation temperature: - 30 ° С . . . + 30 ° С;

Humidity of the Base - no more than 4 wt. % .

Requirements for the base.

The floor surface should be flat. The deviation of the floor surface from the horizontal plane at a length of 2m should not exceed 2mm. If there are slopes in the Base, the deviations are measured from the plane of the Base. The base must be made of concrete or sand concrete and have a strength of at least M200.

Expansion joints in the Substrate must coincide with the joints of floor slabs, expansion joints in the underlying layer, boundaries of reinforcement cards and concrete pouring. The concrete base should be cut off from the walls with waterproofing material.

The ground floor must be waterproofed against groundwater.

The new concrete base must mature to the grade strength, the residual moisture content is not more than 4 wt. % .

The previously used base should NOT contain traces of engine oil, animal and vegetable fats, detergents, previously applied polymer and other coatings (iron, bitumen, etc. ).

The thickness, strength and degree of reinforcement of the concrete base must correspond to the expected load intensity according to SNiP 2.0 13 - 88 FLOORS.

Checking the residual moisture content of the substrate.

Using masking tape, glue a single piece of plastic foil 1x1m in size onto the concrete base. If after two days there is no condensation on the inner surface of the film, and the base under the film has not changed color, then the moisture content of the base is considered satisfactory.

 

Otherwise, further work cannot be carried out!

Preliminary preparation of the concrete base.

If the Base does not meet the requirements for deviations from the plane and / or the presence of contamination, then it is necessary to carry out preliminary operations:

 

Surface milling - leveling.

Removal of oil and other stains to the full depth of penetration (grinding, or milling, or punching).

If the above operations are not effective, a new screed must be installed.

Requirements for equipment and working tools.

Attention! Check all tools for grease!

Almost always, new metal tools (spatulas, roller handles, etc. ) have grease on them. Soak the instrument in a solvent (xylene, solvent) for 4 - 6 hours, carefully remove the grease.

For the application of primer layers , polyamide (polyamide) medium - haired rollers (pile 12 - 14mm) are used. After application, the roller can be immersed in solvent to prevent polymerization.

For the application of the filler and the underlying layer , steel spatulas with a width of up to 600 mm are used.

The spatula must be clean, have a smooth edge, and lie flat against the concrete base . If gaps of more than 1 mm are formed between the trowel and the concrete base, then check the evenness of the edge of the trowel as a rule, or use spatulas of smaller width.

The squeegee is used to evenly distribute the composition in the face layer. The blade must be clean, all whiskers are set equally on the caliper according to the design thickness of the face layer.

A needle (rotary, aeration) roller is used to remove entrained air from the front layer of the coating, as well as to redistribute the material on the surface. The roller should be clean without any traces of composition, moisture, solvents, detergents, lubricants, etc. All segments should be easily movable. When the roller moves along the base, all segments must touch the surface. Otherwise, use a narrower needle roller, similar to a spatula.

Self - leveling soles are used to move on liquid material at many stages of work. Self - leveling soles must be clean and dry and firmly fixed on the feet.

Mixer and mixer. The used mixer must be designed for mixing organic - soluble compositions, have the function of changing the speed, reverse, power - not less than 1 kW. The optimum speed depends on the mixer used, composition grade and composition temperature.

Do NOT use wire mixers!

It is recommended to use double - helix belt mixers.

 

Selection of rotation frequency : when the mixer is immersed on the bottom of the container in the center, a funnel with a depth of ¼ - 1/5 of the total level of the composition should form on the surface of the composition, the entire volume of the composition should participate in movement. Approximate speed:

for a professional mixer - about 500 rpm;

for public mixers - 1000 - 1600 rpm.

An industrial vacuum cleaner is used to remove dust from the substrate before priming and, if necessary, after sanding the filler. Use only specialized equipment, monitor its technical condition, as well as the condition of the brush - it must fit snugly to the base, providing the necessary vacuum and dust suction.

All personnel involved in the performance of work must have personal protective equipment and be instructed in safety. Persons directly involved in laying, putty, priming and having access to the sanded surface must have clean, removable shoes with hard soles.

The use of plastic shoe covers is not allowed!

Determination of the composition consumption for surface priming.

Substrate priming is done in two layers. The last layer (tread) is sprinkled with sand.

Before starting work, it is necessary to experimentally determine the consumption of the composition for priming.

Grind and dust off three sections of the concrete base, with an area of exactly 1 m2. everyone. Apply soil to the areas with a consumption of 300, 200, and 100 g, respectively. Method of application: evenly pour the soil onto the surface with a "snake" and carefully roll it out with a mini - roller (width 10 - 12cm, pile 12 - 14mm), stand for 1 day. Visually determine in which area the gloss appears (shiny surface).

If gloss does not appear even on an area with a consumption of 300g, it is necessary to apply an additional layer of soil 100 - 150g / m2 on this area. After a day, re - check the appearance of gloss.

The total consumption of primer for application is equal to the consumption "to gloss".

Example. On the site with a consumption of 100g - there is no gloss, 200g - gloss, 300g - gloss.

Accordingly, the total consumption of primer for application is 200 g / m2

 

Preparation of compositions for work.

Before starting work, it is necessary to organize a separate place for mixing the compositions.

Spread out the double plastic wrap.

Allocate individual workers for mixing compositions that do not leave the "dirty zone" during work.

When leaving the "dirty zone", change your shoes.

Pay special attention to the presence of individual components on the outer surface of the container.

The main task is to exclude the ingress of composition components ("A" or "B") on the surface of the concrete base!

Swelling and peeling of the coating may form at the points of contact!

Preparation of Soil - 2K / 100.

It is carried out similarly to the Self - leveling floor, only component "A" does not need to be pre - mixed.

After mixing, the soil should be worked out during: at 10 ° С - 1 hour, at 20 ° С - 40 min, at 25 ° С - 30 min.

After this time has elapsed, the viscosity of the Primer will begin to grow, and the penetration capacity will begin to fall.

Self - leveling floor preparation.

Open the container with component "A". Lower mixer to the bottom, but DO NOT touch the bottom.

Turn on the mixer and set the required speed.

Switch the mixer to reverse mode and carefully, against the movement of the component, mix component "A" at the border "bottom of the container - wall of the container". Stir the component on the sides of the container.

Stir component "A" in volume using forward and reverse rotation for 2 - 3 minutes.

Pour in, without interrupting mixing, component "B". Stir using forward and reverse directions for 2 minutes. Pay special attention to dead zones at the bottom and walls of the container.

After mixing, the composition should be allowed to stand for 2 - 3 minutes to allow entrained air to escape.

Pour the finished composition and distribute on the surface.

The residence time of the mixed self - leveling floor in the container is no more than 30 minutes.

Putty preparation.

Mixing of the components of Putty - 2K is carried out completely similar to the Self - leveling Floor.

The surface can be putty both with “clean” Putty - 2K and with its mixture with sand.

For this, dry, dust - free quartz sand is used, fractions from 0.1 to 1 mm, ratio: 1 - 3 parts by volume per 1 part of Putty - 2K.

After mixing the components of Putty - 2K, without interrupting mixing, add sand to it.

Stir in forward and reverse mode until smooth.

The residence time of the mixed Putty - 2K in a container, no more: at 10 ° С - 50 min, at 20 ° С - 40 min, at 25 ° С - 30 min.

 

 

 

It is allowed to use the Self - Leveling Floor for filling the surface (filling with sand is similar to Putty - 2K).

Coating procedure.

Dusting the previously prepared base (see item 6. ). is carried out immediately before applying the first layer of primer. The operation is performed with an industrial vacuum cleaner. The interval between dust removal and application of the layer should be less than 2 hours.

Priming is carried out in two layers with a total consumption measured earlier experimentally (see item 4).

Consumption for each layer is approximately half of the total consumption of the Primer.

It is not allowed to apply primer with a consumption of more than 300g / m2. one layer!

Polymerization time (interlayer exposure) at 20 ° C - 18 . . . 22 h.

 

If the concrete surface does not absorb uniformly, then after applying the 1st layer, it is necessary to additionally prime highly absorbent areas of the base.

If, after applying the 1st layer, glossy areas appear on the surface, it is necessary to check them for the presence of cement laitance and other contaminants. If found, remove, dust off, re - prime.

 

The second layer is applied after the 1st layer has polymerized. During the application of the 2nd layer (tread), sprinkle fresh soil evenly with dry quartz sand of fraction 0.3 - 0.6 mm, consumption 100 - 150 g / m2.

After the second layer has cured, the entire surface should look like a coarse emery. Skips and dull, desaturated areas are not allowed.

Surface filling is performed to seal individual defects of the Substrate (cavities , cracks, etc. ). if necessary, after applying the primer coats.

The polymerization time of the putty: at 10 ° С - 24 hours, at 20 ° С - 12 hours, at 25 ° С - 8 hours.

The underlying layer is carried out in order to: eliminate minor defects in the Substrate; to close pores in the Base up to 0.2mm; elimination of face layer drains. The layer thickness is 1.2 - 1.5mm.

 

The order of operations.

Prepare the composition Bulk Floor.

Apply to the surface in stripes, based on a consumption of 400 g / m2.

Spread carefully over the surface with metal spatulas "on the sdir". Avoid puddles and streaks of excess material.

Fill up in 10 - 20 minutes with an excess amount (more than 1.5 kg / m2) of dry quartz sand of fraction 0.3 - 0.6 mm.

It is carried out in flat shoes.

Sliding (shuffling) movement in flat - toes is NOT allowed when backfilling with sand ! ! !

Any movement (with or without flat - shoes) on a fresh composition covered with sand is NOT allowed ! ! !

Polymerization time of the underlying layer: at 10 ° С - 24 hours, at 20 ° С - 12 hours, at 25 ° С - 8 hours.

After the curing of the underlay, remove excess sand with a hard plastic bristle brush, dust the surface and seal the surface. Spread carefully over the surface for sealing.

Self - leveling floor with metal or rubber spatulas "for sdir". Consumption 300 - 400g / sq.

 

After polymerization of the sealing layer, carry out a thorough visual inspection of the surface for composition drains and other defects. If necessary, fill or abrade the areas with subsequent dust removal.

Face layer.

Define the fill configuration in advance so that the perimeter of the grips to be poured during the entire pouring period does not exceed the critical value. Namely: a fresh batch of material must be docked with the boundary of the previous batch no later than 40 minutes after the start of laying the previous batch.

When planning the fill configuration, keep in mind that there must be expansion joints that are the boundaries of the fill grips.

It is necessary to preliminarily limit the predicted poured area using masking tape for the convenience of continuing work after a break and marking a map of expansion joints.

The order of operations.

Prepare the composition of the Self - leveling floor for work.

Apply to the surface in stripes, taking into account the design thickness of the topcoat.

Spread the composition evenly over the area with the squeegee.

After 10 minutes, but no later than 40 minutes. thoroughly and evenly roll the composition with a needle roller to remove entrained air and even out the color and texture of the surface. It is carried out in flat shoes.

Sliding (shuffling) movement in flat shoes is NOT allowed ! ! !

The minimum consumption required for self - leveling of the face layer depends on the temperature of the base and ranges from 1.0 kg / m2. at + 25 ° С up to 1.8 kg / m2 at + 5 ° C.

Working time with self - leveling floor, poured onto the surface: at 10 ° С - 3 hours, at 20 ° С - 1.5 hours, at 25 ° С - less than 1 hour.

The polymerization time of the front layer: at 10 ° С - 24 hours, at 20 ° С - 12 hours, at 25 ° С - 8 hours.

 

Do not scrape off liquid composition residues from the walls of the empty bucket, as mixing on the walls may not be complete, which will lead to the formation of blisters on the surface of the coating.

Seam sealing. After the application of the self - leveling layer and its polymerization, fill the expansion joints with polyurethane sealant according to the manufacturer's instructions.

After the self - leveling floor device.

After 3 days - foot traffic.

After 7 days - full mechanical load.
