ElaProof Primer installation instructions

Applications

Porous materials such as new or old concrete surfaces, mineralite, plastered surfaces and gypsum. The treatment improves the adhesion of ElaProof to the substrate and clogs the pores of the substrate. Air bubbles rising to the surface are often a sign of too little priming. Suitable for indoor and outdoor use.

Chassis

Before applying ElaProof Primer, dirt, grease, dust and other loose material are removed from the substrate and the substrate is cleaned of old paint and surface layers.

• The new concrete floor surface must be at least 4 weeks old before coating, sufficiently strong and hardened so that the moisture in the concrete casting is bound and the surface is sufficiently dried.

• It is also important to remove cement adhesive from concrete surfaces, for example by sanding, so that the primer penetrates well into the pores of the concrete.

• If porous mineral substrates are to be cleaned, the requirements and legislation for asbestos removal must be complied with. After priming, ElaProof can be applied to new concrete castings when the relative humidity of the concrete, measured from the casting surface, does not exceed 90% RH. For fresh concrete casting, ElaProof test coating is recommended after priming.

Instructions

Before application, dirt, grease, dust and other loose material are removed from the substrate and the substrate is cleaned of old paint and surface layers.

Operating temperature:

(air and surface) over +5°C. The primer is applied in a thin, even layer so that all the substance is absorbed on the surface and no ponds are formed. Only one treatment is sufficient if the substrate is not very dry and absorbent.

Tools:

roller, brush or syringe. Tools are cleaned with water.

Shelf life:

12 months from manufacture, see jar. The product must be protected from frost and direct sunlight.

Drying time:

1-4 h depending on conditions and substrate.

Mixing ratio:

1 part ElaProof Primer and 2 parts water (1: 2). Make the mixture in a sufficiently large, clean container. First measure the water and then add ElaProof Primer. Stir gently.

Consumption:

Depends on the roughness and porosity of the substrate, typically 0.1 to 0.5 l / m2 (primer diluted with water)

Chassis • Consumption l/m²

  • Cement board • 0,1 – 0,2
  • Brick and concrete • 0,1 – 0,15
  • Lightweight concrete blocks • 0,1 – ,02
  • Highly absorbent base e.g. Siporex • up to 0,5

N.B! Always mix the product before use. The mixture diluted with water must be used within a week. The mixture is a milky liquid that dries to a transparent surface and leaves a breathable surface.

Elaproof Indoor instructions for use

Conditions and storage

ElaProof shall be applied in temperatures over +10°C (air and surface) and relative humidity of less than 80%.

The product can also be used on new concrete substrates with remaining residual moisture. In this case, the maximum moisture content is 90% RH measured at the assessment depth A, following the instructions of RT Card 103333 (this applies in Finland, please check your local instructions). The surface of the concrete must be drier than assessment depth A at the time of coating. If it’s a concrete substrate that has become wet after the fact, for example, due to rain, the moisture content should be a maximum of 85% RH at assessment depth A and a maximum of 75% RH on the surface of the concrete. For dense substrates like metal and felt, they should be dry at the time of coating.

ElaProof should be installed at temperatures above + 10°C. Surface temperatures must also be at least + 10°C. The product temperature must be +10 to + 30°C when the product cures and films. Do not freeze during transport or storage, or store in direct sunlight or at temperatures above + 40°C. The product should be stored in sealed packages to prevent water evaporation.

Surface

The suitability of the base and structures for air sealing must be ensured. The suitability of ElaProof Indoor for the platform should be tested on site. The substrate must be solid, strong, uniform and not cracked so that there is no air path from the substrate outside the seal. Cavities and crevices larger than 2 mm in the substrate are filled or levelled with ElaProof Indoor up to a thickness of 10 mm or other elastic compound (no acrylic), polyurethane or filler. The moisture content of the concrete substrate should not exceed 90% RH.

Surface cleaning

All non-adhesive layers are removed from the surface. The surface must be free of dirt, dust, loose water, and other loose material. The surface is cleaned of cement adhesive, for example by sanding.

Priming the substrate

ElaProof Primer is used on porous surfaces to ensure adhesion. ElaProof Primer is diluted with water in a ratio of 1 part primer to 2 parts water (1:2). The consumption of the primer depends on the substrate and is applied in such a way that all the substance is absorbed into the substrate. The primer is allowed to dry for 1-4 h depending on the conditions. ElaProof Primer is especially used on porous, dusty, or otherwise difficult to clean surfaces. It is a good idea to test the suitability of the primer on the substrate separately before installation, for example by triangulation and tensile strength tests on the installed coating model.

Installation

ElaProof Indoor must be mixed thoroughly before installation. It is recommended to install ElaProof Indoor first to seal the joints and then to treat the planar surfaces. Careful installation work ensures a functional result.

Joints

The sealing principles of the connections are shown in the drawing ElaProof Indoor air sealing details. For joints with possible movements, ElaProof Base Fabric is used. In structures where there is no movement, such as in old structures where drying shrinkages and depressions have already occurred, the installation can be done without a base fabric. However, we still recommend the use of a base fabric.
The seal is overlapped on the surfaces to be sealed

  • on concrete surfaces at least 30 mm
  • on wooden surfaces at least 15 mm

Using a base fabric for sealing

Apply a large amount of ElaProof Indoor sealing compound to the cleaned, flat surface with a spatula or brush so that the compound adheres to the substrate throughout. In structures where movements are possible, the ElaProof Base Fabric is pressed into the wet mass, for example with a spatula, so that no air is left between the base fabric and the base. Apply a 2nd coat of ElaProof Indoor on top of the base fabric so that the base fabric stays in place and is covered throughout. Second coat ElaProof Indoor is easiest to apply after the first coat has dried. The joints of the base fabric are overlapped by at least 30 mm and the base fabric is glued with ElaProof Indoor to the underlying support fabric. Particular attention must be paid to the tightness of corners and bushings.

Sealing without base fabric

In structures where no movement occurs, the sealing is done twice with ElaProof Indoor sealing compound to a minimum thickness of 0.5 mm of the final dry film. Apply a large amount of ElaProof Indoor sealing compound to the cleaned, flat surface with a spatula or brush so that the compound adheres to the substrate throughout. The first layer is allowed to dry before installing the second sealing layer. Particular attention must be paid to the tightness of corners and bushings. The surface is touch dry after 3-4 h and walk-resistant after 15 h after installation (20 °C, RH 45 %, 1 l/m2).

Sealing of planar surfaces

ElaProof Indoor is applied to the flat surfaces with a trowel, roller, brush, or spray. More layers may be required to provide sufficient film thickness on the wall, ceiling, or other floating surfaces. It is recommended to apply the next coat after at least 3 hours. The recommended material consumption is a total of 1.0 – 1.4 l / m2. The surface is touch dry after 3-4 h and walk-resistant after 15 h after installation (20 ° C, RH 45%, 1 l / m2).

Requirement

Successful airtightness requires a dry film thickness of at least 0.5 mm, which on a flat surface corresponds to a material consumption of 0.8 l / m2. The finished coating must be well adhered to the substrate throughout. The material should be well bonded and there should be no holes in the coating. Verification of success for airtightness usually requires quality assurance, which can be carried out, for example with marker tests in accordance with Finnish RT Card – RT 14-11197.

Cleaning of tools

Clean tools with water.

ElaProof H Instructions for use

Preparations

  • Clean the surface carefully of dirt, sand, grease, loose water, organic vegetation, old layers of paint or coatings and other frail material.
  • Depending on the condition of the surface, use a high-pressure washer or a brush for cleaning.
  • It is recommended that porous surfaces, such as concrete, are prepared by applying ElaProof Primer for securing optimal adhesion and tightness of the coating.
  • When needed, use protective equipment. ElaProof as such is safe but it is always strongly recommended to use e.g. eye protection and safety equipment when working on roofs.

Sealing of holes and crack

  • Smaller holes and cracks can be filled and covered with ElaProof without special preparations.
  • For larger holes and cracks (over 2 mm wide, over 5 mm deep) use of ElaProof Base Fabric is recommended. First spread ElaProof on the edges of the hole or crack. Then press Base Fabric into the moist ElaProof mass. Ensure with a trowel or a spatula that there are no wrinkles in the Base Fabric and it is firmly attached to the ElaProof mass. Finally, spread another layer of ElaProof over the Base Fabric before or after the first layer has dried.

Application

  • ElaProof shall be applied in temperatures over +10°C (air and surface) and relative humidity of less than 80%.
  • ElaProof H mass can be applied easily with hand tools such as spatula or short-hair brushes.
  • If necessary, the product can be diluted 1 to 2 percent by weight (1.7 to 3.4 dl for a 15 litre container). If you dilute the product, start with a small amount of water and add more if necessary.
  • The right amount of ElaProof for surface-covering coating depends on the evenness and porosity of the surface. For smooth surfaces an average of 1.0 l / m² is required, whereas approx. 1.8 l / m² is required for rough concrete surfaces. Sufficient coating thickness secures its long-term durability.
  • ElaProof H can be applied in one or several layers. It can be applied also on damp or rusty underlayer.
  • The product can also be used on new concrete substrates with remaining residual moisture. In this case, the maximum moisture content is 90% RH measured at the assessment depth A, following the instructions of RT Card 103333 (this applies in Finland, please check your local instructions). The surface of the concrete must be drier than assessment depth A at the time of coating. If it’s a concrete substrate that has become wet after the fact, for example, due to rain, the moisture content should be a maximum of 85% RH at assessment depth A and a maximum of 75% RH on the surface of the concrete. For dense substrates like metal and felt roofs, they should be dry at the time of coating.

Drying

  • The ElaProof H coating compound dries by evaporating water.
  • The drying time depends on the layer thickness, the ambient temperature and relative humidity, dew point, and the absorbency of the surface to which the mass has been applied.
  • Drying time
  • • Touch dry (+20°C, 50% RH, 1,5 l/m²) 3 – 4 h
  • • Touch dry (+6°C, 25% RH, 1,5 l/m²) 40 h
  • • Fully dry (+20°C, 50% RH, 1,5 l/m²) 1 day
  • • Full mechanical properties (+20°C, 50% RH, 1,5 l/m²) 3 weeks

Tool cleaning and waste handling

  • Wash the tools and surrounding surfaces with water immediately after application. After drying, cleaning of ElaProof can be done mechanically (e.g., the spatula can be cleaned with a knife) or with organic solvents (e.g., xylene).
  • ElaProof H packaging can be disposed as energy waste. Dried ElaProof can be disposed as normal mixed waste.

Please note!

  • Store ElaProof H coating mass in temperatures between +10°C … +40°C and protected from direct sunlight. The product must not freeze before use.
  • ElaProof H can be stored unopened for minimum 12 months. After use, close the bucket carefully for maximising the storability of the remaining coating mass.
  • A dried ElaProof H coating can be painted with elastic, waterborne, breathable paints. It is advisable to test the compatibility of ElaProof and a specific paint in advance.
  • More technical information is available from info@buildcare.fi.
