Real Project
Project Data
-
City of Uzhgorod.
-
Operated terrace.
- Base: concrete.
A task
-
It is necessary to carry out waterproofing of the operated terrace.
- A polymer coating for a terrace must withstand physical and mechanical stress, be waterproof, UV-resistant and elastic.
Polyurethane coating installation
Solution
With the help of a team of specialists, an option was proposed to apply the HYDROLAST-PU WHITE system.
-
HYDROLAST-PU WHITE is an elastic waterproofing and a polymer floor for pedestrian loads, two in one.
-
HYDROLAST-PU is a liquid polyurethane waterproofing membrane.
- HYDROLAST-PU is a viscous one-component polyurethane-based liquid that polymerizes after application and forms an elastic membrane with high adhesion to all building substrates.
HYDROLAST-PU
|
Polymerizes upon contact with atmospheric moisture and creates a single (seamless), elastic, waterproof membrane;
|
|
Completely waterproofs horizontal and vertical surfaces from the outside, providing resistance to positive water pressure;
|
|
Possesses high mechanical durability and resistance to attrition;
|
|
Let's apply to tanks with stagnant water;
|
|
Due to its excellent elasticity, it can bridge cracks up to 2 mm;
|
|
Vapor-permeable and allows structural elements to "breathe";
|
|
Provides high UV resistance and reflects the sun's rays well (providing good thermal insulation in summer);
|
|
It does not soften (“does not flow”) in summer and does not harden (does not become brittle) in winter, since it retains its mechanical properties at temperatures from -30 to +80 ° C.

Polyurethane floors
Application
HYDROLAST-PU can be applied to both absorbent (concrete, cement mortar, wood) and non-absorbent substrates (metals, asphalt, ceramic tiles, old acrylic coatings).
HYDROLAST-PU is mainly used for:
-
waterproofing and protection of concrete structures such as bridges, tunnels, foundations, etc.;
-
waterproofing of terraces, balconies, inclined and flat roofs;
-
UV and weather protection of bituminous waterproofing membranes;
-
waterproofing under tiles on balconies, bathrooms, kitchens, etc.;
-
protection of heat-insulating layers of polyurethane foam;
- waterproofing florists.

Stages of work on the installation of a polyurethane coating
Concrete base repair
Before applying polyurethane waterproofing, the substrate must meet certain parameters. First of all, it is required to repair the concrete base.
So at the beginning:
-
repaired all visible cracks, small shells, large potholes, partially restored a small area of the concrete floor, using a repair mortar , with a quick set of strength VIMACRET RAPID.
-
VIMACRET RAPID - fibre-reinforced, acrylic, ready-to-use repair mortar, fast curing.
- VIMACRET RAPID is a high quality, ready-to-use repair mortar with a fast setting time of 30 to 35 minutes. This makes it possible to perform an uninterrupted cycle of work.
Concrete floor repair
The advantages of VIMACRET RAPID are:
-
excellent adhesion to the surface of the base;
-
no coagulation shrinkage;
-
high mechanical strength;
- the material qualifies as a ready-mix concrete repair type PCC/R3 according to ΕΝ 1504-3.
VIMACRET RAPID is recommended as a fast curing cement mortar intended for:
-
fastening and anchoring of metal structures and mechanisms;
- preparation and repair of bases, before applying WATERBLOCK coating waterproofing mixture (filling voids and other defects in the surface of concrete structures, manufacturing sealing perimeter skirting boards, grooves, fillets) and sequentially performing a continuous cycle of work during sealing.
Floor repair
Surface preparation
After repairing the concrete base, mechanical processing of the concrete was performed using a grinder.
With the help of grinding, eliminated:
-
weakly holding cement particles (cement milk);
-
the concrete slab has become monolithic and homogeneous;
-
open pores for better soil penetration;
-
created a light rough surface that will increase the adhesion of the finished polyurethane floor.
- dusted the concrete base with an industrial vacuum cleaner.
Dedusting concrete floor
Applying primer primer
To strengthen the concrete base and increase the adhesion of the polyurethane coating to concrete, a water-based primer VIMEPOX PRIMER-W was used.
VIMEPOX PRIMER-W is a two-component water-based epoxy primer for concrete floors.
VIMEPOX PRIMER-W - is a water-soluble two-component epoxy system.
-
It has high adhesion to cement substrates and excellent resistance to mechanical stress.
- The material can be applied on dry and slightly damp surfaces (without standing water), as well as indoors, as it does not have a strong smell of solvents.
Application
-
VIMEPOX PRIMER-W is used as a primer on cementitious substrates (concrete, cement mortars) before applying VIMEPOX FLOORING and VIMEPOX TOP COAT epoxy coatings and VIMEPOX F-COAT and SP COAT epoxy paint.
-
After application, a compaction of surface pores, an absorbent base and a single continuous surface is created, as well as dust residues are neutralized.
- This ensures optimum adhesion for topcoat application.
polymer flooring
Application of VIMEPOX PRIMER-W as an impregnation:
-
Improves the surface strength of the concrete base.
-
Solves the problem of slightly exceeding the permissible humidity.
-
When added to VIMEPOX PRIMER-W quartz sand M32 (Ø 0.1 - 0.4 mm) in a ratio of 1:5, the resulting mixture can be used to make a mortar for filling pores and cracks.
- VIMEPOX PRIMER-W can be used to prime surfaces before applying various polyurethane coatings.
Polyurethane floors installation
Application of polyurethane waterproofing
After the primer was dry, two coats of polyurethane mastic were applied in two coats, 24 hours apart.
The advantage of the polyurethane system for the terrace
|
Elasticity 800% |
Allows the material to withstand temperature changes (temperature shock);
Covers cracks in the concrete base up to 2 mm;
Withstand dynamic, seismic and deformation loads. |
|
Shore hardness 65 |
It is a very strong base, not soft, capable of withstanding light to medium foot traffic. |
|
Chemical resistance |
Resistance of polyurethane coating to light acids, alkalis, water. |
|
UV resistance |
The ability of the polyurethane coating not to collapse under the influence of sunlight. |
|
energy saving |
Due to the white color, the polyurethane coating can be used in the Cold Roof system.
This is when the sun's rays are reflected from the base, respectively, the roof does not heat up and you spend less electricity on cooling the room under the terrace in the summer |
|
High adhesion to concrete |
This is the ability of the material to firmly adhere to the base, which gives the coating excellent characteristics for exposure to wind loads. |
