5 The substrate must be sound, free from loose sections, dust and oils. Brittle or dusting surfaces must be primed first with the micromolar stabilizer AQUAFIX or the SOLVENT BASED PRIMER of DUROSTICK. Surfaces, already coated with paints and/or adhesives (such as ceilings), must first be stripped from their coating(s) and they have to be thoroughly cleaned in order to ‘receive’ smoothly dB Block. Steel surfaces are properly prepared by applying the appropriate primer. Apply the ready-to-use product as is, with a 4-6mm notched trowel to achieve a coat thickness between 2-3mm. Continue by smoothing the surface with the straight edge of the notched trowel to yield a satisfactory smooth surface. The product can also be applied with a finishing/spackling trowel, depending on the coating thickness and the application. In hard to reach areas and corners, apply the product in 1-2 coats of equal thickness, with a wide brush or an emulsion brush. Please allow for 5-7 hours to pass between coats, always depending on the ambient conditions (temperature, humidity). For better workability, dilute it up to 5% with water, depending on the application. Surface preparation Use Apply it on interior and exterior, horizontal or vertical building surfaces, such as plaster, concrete, plaster board and lightweight construction surfaces, wood surfaces, wood constructs form OSB, marine grade plywood, etc., metal surfaces and steel construction surfaces, aluminum panels, sheet metal, polyester, plastic surfaces, PVC piping and a variety of other materials. dB Block is ideal for application in new, under construction or existing buildings, plus for hotel and store renovations, catering hall renovations, etc. Applications
6 Apply dB Block with remarkable ease on interior and exterior walls and ceilings made of marble based plaster. Apply the product in a 2-3mm single coating. The application of a second coat is optional and depends on the requirements of the project. It can be applied 5-7 hours after the application of the first one, always depending on the ambient conditions (temperature, humidity). Achieve a perfectly smooth finish of all interior surfaces by applying the elastomeric putty STUCOFIX ELASTIC PUTTY. Once the putty is thoroughly dry, usually a day later, paint using the ecological emulsion paint SUPER ECO of DUROSTICK, available in hundreds of shades. Create exceptional and unique styles on wall surfaces by choosing the microcement in paste form DS-258 DECO MICRO FLEX or the decorative cement mortar DS-259 DECO MICRO RESIN directly on the surface of the dB Block. Continue by protecting the newly decorated surface by coating it with the odorless varnish DECOFIN AQUA or DECOFIN AQUA PU of DUROSTICK.

Once coated with dB Block, wall and ceiling surfaces are soundproofed, waterproofed, thermally insulated and they are also protected from cracks. dB Block lines walls and ceilings with a flexible, highly watertight protective coat. It effectively covers hairline and micro cracks, prevents their reappearance and protects the coated surfaces from the formation of new ones. Exterior wall surface application
8 Construction surfaces made of gypsum board and cement boards or fiberboards, on walls, ceilings and partitions in general, are an ideal application field for dB Block. Apply it without priming, without taping or even spackling over the screw holes. Coat the surfaces and give them soundproofing, waterproofing, thermal insulating and anti-vibration properties, while ensuring their protection from future cracks. Paint, spackle or line the coated surfaces in the same manner, as described above. Existing or new drywall and lightweight construction surfaces The flexible properties of dB Block make it ideal for applications on wood surfaces and constructs with any type of wood. Specifically, OSB construction surfaces, when lined with dB Block and without the use of any primer, they are waterproofed, soundproofed, they acquire antivibration properties, and they are ensured against cracking of the joints and of their final lining coat. The use of the wood preservative DUROXYL WOOD Protection/Conditioner is completely optional. However, it is recommended for the long term protection of the uncoated MDF or marine grade plywood surfaces and the prevention of their infestation from wood boring insects. The fortified with dB Block wood surfaces can be coated with the ready-to-use elastomeric STUCOFIX ELASTIC PUTTY and all interior surfaces can be painted with the ecological emulsion paint SUPER ECO of DUROSTICK, available in hundreds of colors. dB Block surfaces can also be coated with one of the flexible cementitious microcement products of DUROSTICK, but also with tiles or any other lining of choice. Wood surfaces and wood constructs
9 Metal surfaces and metal construction Μetal buildings, aluminum panels, steel frame lofts and any other metal structure, easily ‘accepts’ the application of dB Block. The application of dB Block dramatically reduces the sound of rain or other sounds generated from the exterior environment. dB Block also acts as a waterproofing coat that effectively protects metal surfaces from moisture and water, naturally preventing their corrosion. Due to its unique flexibility, it successfully adjusts to the expansions and contractions of the surfaces, ensuring the protection of the flexible lining materials that will eventually coat them, from crack formations. dB Block also acts as cold and heat barrier, thus contributing to the energy upgrade of the building, resulting in energy saving. Unpainted metal surfaces are first primed with METAL PRIMER of DUROSTICK.
10 In renovation projects, expectations are quite demanding. Delivery deadlines and ease of quick turnaraound are of major importance. Apply dB Block as is, directly over the soon to be renovated surface, without removing/ demolishing the existing floor linings Smooth the applied product with the straight edge of the trowel. Its application creates the perfect bonding conditions for the lining that will follow. It smoothes surface defects and it also waterproofs, soundproofs, thermally insulates and ensures protection from future crack formations on the new linings. Once fully cured, it facilitates the use of flexible tile adhesives, such as ELASTIC or EXTRA POWER of DUROSTICK. Grout the new floor surface using the epoxy grout DUROPOXY or the VITREOUS TILE GROUT 1-10mm of DUROSTICK. dB Block also ‘works’ perfectly with flexible microcement, such as DS-252 FLEX of DUROSTICK. Use it to also install/adhere wood floors and linings, without the need for any other adhesive. Even in newly built constructions or in places that change their use, dB Block is applied directly on solid cementitious substrates and concrete, without primer. For all of the above reasons -among other things- dB Block is becoming a favorite product of renovations and contractors alike.

11 For several years, cementitious microcement has been the absolute product in decoration and design. The product that dreams are made of... Multifunctional, versatile, it can be applied on every possible surface or object. It has become a favourite tool in the hands of architects, interior decorators, and those with aesthetic value and appreciation for the unique. It has been applied by experienced professionals, in homes and stores, malls and hotels, everywhere there was a need for decoration with a unique point of view. Over time, however, the main flaw of the product was uncovered: Superficial cracking. Now dB Block comes to safeguard the installation, it comes to create safer application conditions with its antivibration protection and its ability to prevent cracks when used as a substrate. It successfully and constantly receives and absorbs expansions and contractions of the substrate. At the same time, it waterproofs the very same substrate and blocks rising damp. By completing the above tasks, it ensures the integrity of all flexible cementitious microcemento linings, such as DS-252 FLEX and DS-256 FLEX VELVET of DUROSTICK. dB Block together with flexible microcement functions as one system that yields sound applications with durability over time and through use. In addition, all coated surfaces will now have excellent bonding conditions of the microcement with the substrate, as well as waterproofing, soundproofing and thermal insulating properties. Residential and commercial, interior and exterior spaces, they are all considered exceptional application fields for the system. Even microcement applications permanently exposed on exterior surfaces, such as balconies, terraces, or even rooftops used as roof garden spaces, are proved to be perfect application fields for this multifunctional and protective product. Even microcement applications permanently exposed on exterior surfaces, such as balconies, terraces, or even rooftops used as roof garden spaces, are proved to be perfect application fields for this multifunctional and protective product. In the end, all projects decorated and crafted with microcement require protection with water or a solvent-based acrylic, polyurethane epoxy or polyurea varnish, depending on the requirement and nature of the application. Plaster Concrete DS-252 FLEX Protective varnish DUROFLEX-PU dB Block Microcement installation on floors made of mosaic or ceramic tiles or even new, bare floor surfaces Application as a crack protection and prevention system Fiberglass mesh DS-4160
12 Applying dB Block as an undercoat for roof and terrace waterproofing coatings ensures the absolute waterproofing of those surfaces long-term since the undercoat will not age. Even if the waterproofing coat gets damaged or fails, the substrate will not get harmed. Apply it directly over concrete, without priming, to absolutely cover hairline and micro cracks, without using any mesh tape, and at the same time ‘prevent’ any new ones from appearing. Its application will also maximize the waterproofers coverage. The product lines the entire surface(s) with a uniformed and flexible protective coat, without any seams nor joints. Surfaces that are not sound or they are brittle should be primed with the water based micromolar stabilizer AQUAFIX of DUROSTICK, prior to the application of dB Block. Already watertight roofs and terraces with well adhered asphalt roll roofing systems or existing cement roof tiles can gain new life instantly. After the meticulous cleaning of the surface and the removal of any loose sections, apply the product on the entire surface. Make sure that the product is applied to the parapet walls as well, in order to create a waterproof, ‘basin-like’ area. Due to its exceptional flexibility, dB Block will adjust over time to any substrate movement and will remain unaffected by ground vibrations and temperature variations. This will offer protection as well as extended life of the top waterproofing coating. Depending on the use of the roof or terrace(*), the top waterproofing coating product can be a flexible cementitious waterproofer, such as HYDROSTOP ROOF or HYDROSTOP 2 COMPONENT. We also suggest the use of acrylic waterproofers, such as DS-220 or polyurethane based waterproofers, such as HYDROSTOP-PU of DUROSTICK. *HYDROSTOP ROOF, HYDROSTOP 2 COMPONENT: suitable for heavy use. For space use with heavier demand, the cementitious waterproofers can be lined with tiles, natural stone slate and other lining material. DS-220, HYDROSTOP PU: suitable for foot traffic, without stic king (normal use)) By combining the use of dB Block as a system with a top waterproofing coating, one can easily, quickly and affordably achieve: • The creation of an effective protecting coat of the roof or terrace, the upmost exposed construction surface of a building to the elements (solar radiation, rain, frost, snow). • The protection against moisture and chemical pollutants of the environment from penetrating into the concrete slab of the roof, causing concrete carbonation and rebar corrosion. Those will eventually cause significant damage, that could affect the structural stability of the concrete slab and of the building as well. • The reduction of the temperature difference between the indoor and outdoor environment, thus significantly reducing vapor condensations and the development of mold and mildew (due to its energy efficient skills). • The reduction of energy consumption that is required to heat and cool the underlying interior spaces of the building. • The delay of the ageing process of the top waterproofing coating(s) and doubles their waterproofing capabilities.

14 Thermal insulation systems for building facades are intended to energy upgrade buildings by thermally insulating them. The incorporation of dB Block in the application process fortifies the thermal insulating properties of those systems. It ensures their watertightness, crack prevention and protection of the top-coat plasters and soundproofs from airborne noises, generated from the exterior environment. This system upgrade provides comfortable living conditions for the people occupying the spaces of the building. Apply it, without primer, over the thermal insulation adhesive that is coating the insulation boards. Once cured, apply the top-coat plaster over it. Plaster such as the silicone plaster HYDROSTOP SILICONE PLASTER, or the acrylic plaster HYDROSTOP ACRYLIC PLASTER. Alternatively, use the cementitious and flexible plaster HYDROSTOP PLASTER ELASTIC. Complete the application of the cementitious and flexible plaster, by priming and painting it with the thermoceramic, energy efficient paint THERMOELASTIC COLOUR of DUROSTICK. The plasters in paste form are available in 44 color chart colors. dB Block can also be applied externally on any existing construction, wherever the application of a thermal insulating system is not possible. It adheres perfectly, without primer, to plastered or painted walls, and covers capillaries and micro cracks. The product yields the sum of its many properties and ultimately upgrades the energy efficiency of the building. Depending on the aesthetic requirement, it can be smoothed over with the straight edge of the trowel or it can even be spackled (for a perfectly smooth surface. Complete the application by painting, using the elastomeric acrylic paints of DUROSTICK, such as D-80 HYDROSTOP ELASTIC or THERMOELASTIC COLOUR.

15 Interior thermal insulation system for buildings The interior thermal insulation and sound protection, which is achieved through the application of dB Block of DUROSTICK, is the most suitable solution for existing and new residences. Its application will easily, quickly and economically upgrade their thermal and sound insulation value. Due to its small application thickness (2-3mm), it is ideal for interior (wet, cold) walls, ceilings, attics, closet interiors, without ‘disturbing’ the functionality of the application area. For any building that cannot be externally thermally insulated, such as historical and preserved neoclassical buildings or apartment buildings with owners who do not agree to external interventions, dB Block is the only viable solution. It soundproofs and thermally insulates the interior spaces of residences with resilient and flexible soundproofing and energy efficient protective coat, that is capable of ‘interrupting’ the flow of airborne external, disturbing noises. As for its energy efficiency, it will reduce the temperature difference between the interior and the exterior environment, drastically reducing the condensation of water vapor, that results in fungal growth and mold formation. The natural result of the dB Block application is to achieve energy savings of up to 30%. Walls and ceilings coated with dB Block are soundproofed, waterproofed, and thermally insulated, while at the same time they are protected from cracks.
16 What is sound? Sound is the mental perception of waves produced by objects that vibrate. The sound waves are decoded by the complex acoustic means of humans, our ears. To measure the volume level of a sound, we use the decibel scale (dB). The scale was named in honor of the American physicist specializing in acoustics, Alexander Graham Bell (1847-1922), more widely known for the invention of the telephone. The invention of the telephone is based on the variations in the air pressure (when one speaks to the receiver), formed by the amplitude of the sound wave. What is noise? Noise is any unwanted sound. Airborne is the noise transmitted through the air. Structure borne is the noise transmitted through solid objects, such as the structural components of a building. Impact noise is the structure borne noise generated from impacts, strikes etc. What is noise pollution? Noise pollution is the bothersome noise in the environment. It is the second environmental hazard to human health, next to environmental pollution. A World Health Organization study has shown that exposure to noise pollution is detrimental to human health. According to the research, the continuous and long-lasting exposure of the human body to noisy environments causes hearing damages, headaches, dizziness, nausea and even heart problems. Blood pressure is increased, stress is exacerbated and psychosomatic illnesses appear. Sleep, concentration and also learning abilities are all disturbed. ‘Victims’ of the degradation of the acoustic environment are, above all, the people living in large cities, with public transport being the largest source of noise pollution. Due to their nature, countries that qualify as vacation destinations are exposed to noise in all tourist attraction spots. Let us take a closer look at the attitudes of the people living in large cities... A large percentage of them are irritable and easy to upset, sometimes violently erupting without obvious reasons and present psychosomatic problems. A few words about sound
17 The human organism is not ‘made’ to deal with loud and aggressive, constant noises. Indicatively, we present a table with common daily sounds. Sound description Sound volume in (dB) Leaves blowing in the wind 20 Interior of a quiet home 40 Store or shop 70 Busy street 80 Thunderbolt 100 Concert - Club 120 The impact of noises on humans depends directly on the frequency of exposure of each individual to them, the duration of the exposure and their physical condition. Children are more sensitive to noises. Protect them, ensuring acoustic comfort conditions, at least in their home. 68dB 80dB 71dB 81dB 74dB 85dB 77dB 130dB According to allowed noise limits, sounds that do not exceed 68dB, characterize the sound environment as Comfortable. Sounds up to 80dB, characterize the sound environment as Very noisy. Sounds that do not exceed 71dB, characterize the sound environment as Good. Sounds exceeding 81dB, characterize the sound environment as Aggressive. Sounds that reach 74dB, characterize the sound environment as Tolerable. Chronic exposure to noise levels above 85dB leads to loss of auditory acuity. Sounds that reach 77dB, characterize the sound environment as Noisy. It is the level where sound causes pain and can lead to the rupture of the ear drum. From acoustic comfort to noise ADJACENT ROOM ADJACENT ROOM ADJACENT ROOM AIRBORNE NOISE IMPACT NOISE
