TECNOCOAT POLYUREA AND DESMOPOL POLYURETHANE SYSTEMS
TECNOPOL systems are ideal for waterproofing and protecting any project, regardless of its geometry, surface material or required finish.
The quality of the system applied, whether TECNOCOAT or DESMOPOL, is recognised worldwide thanks to the numerous certifications and approvals it holds (EOTA, BBA, EN, ISO...). Tecnopol's technical team has developed a system to satisfy all the professionals involved in the construction process: designers, engineers, architects, builders, applicators and end users.
TECHNICAL GUIDELINES
SYSTEM DETAILS
TECNOPOL flat roof coverings
1 Surface preparation
TECNOPOL finishes for flat roofs and terraces can be applied on a wide range of existing surfaces (mortar, cement, traditional waterproof sheeting, ceramics, wood etc), using a few simple steps.
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface.[product primer-pu-1050]

3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Finish layer
The TECNOPOL finishing coat consists of an aliphatic polyurethane resin, highly resistant to UV rays and hard wearing (can be walked on), and to which an anti-slip finish may also be added (conforms to CTE DB SUA, Class 3 classification (Rd >45), according to UNE-ENV 12633:2003).

Ceramic covered terrace
1. Surface preparation
Ceramic finish flat roof flooring can be applied on whole wide range of existing surfaces (mortar, cement, traditional waterproof sheeting, acrylic paint, existing ceramic paving, wood etc).
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface.

3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Mechanical Fixing
To improve adhesion of the mortar and facilitate the positioning of the final paving, an anchoring coat should be first applied by sprinkling dry silica over a fine layer of polyurethane resin.
5. Finish layer
The finishing layer of ceramic material will be positioned directly on top of the anchoring coat.
Plot paving
1. Surface preparation
Our finishes for raised flooring on roofs and terraces (using individual pieces positioned directly over the surface or via bases or pedestals) can be applied on a wide range of existing surfaces (mortar, cement, traditional waterproof sheeting, ceramics, wood etc).
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface.
3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Finish layer
The raised flooring finish will then be positioned directly over the waterproofing membrane.
Flat roofs for vehicle traffic
1. Surface preparation
Our finishes for flat roofs designed for vehicle traffic can be applied on a wide range of existing surfaces, typically concrete, using a simple preparation process, and are designed to meet aesthetic demands as well as waterproofing considerations.
2. Primer
A primer resin should be first applied to ensure adhesion to the surface.
3. Waterproofing membrane
The TECNOCOAT waterproof membrane is applied directly over the primer resin.
4. Finish layer
The finishing coat consists of an aliphatic resin, highly resistant to UV rays and hard wearing (can be walked on), and to which an anti-slip finish may also be added (conforms to CTE DB SUA, Class 3 classification (Rd >45), according to UNE-ENV 12633:2003)..

TECNOFOAM inverted flat roofs
Flat roofs with thermal insulation based on TECNOFOAM polyurethane foam applied to the outside of the system are known as “inverted”. These offer a simple and effective solution solely requiring protection for the foam from UV rays which would otherwise degrade the aromatic material.
1. Surface preparation
Finishes for flat roofs with thermal insulation based on TECNOFOAM polyurethane foam may be applied on a wide range of existing surfaces (mortar, cement, traditional waterproof sheeting, ceramics, wood etc), using a few simple steps.
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface.
3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Isolation layer
The coat of TECNOFOAM poyurethane foam is applied directly onto the membrane before it has completely polymerized.
5. Finish layer
For UV ray protection a final coat should be applied using a highly resistant aliphatic polyurethane resin.

Traditional inverted flat roofs
Flat roofs with thermal insulation (in this case polystyrene panels) located on the outside of the system are known as “inverted”. These offer a simple and effective solution where one simply needs to take extra care with the ballasting given that mechanical attachment will not be possible as this type of flooring is positioned on top of the waterproof membrane.
1. Surface preparation
Ballasted flat flooring with thermal insulation may be applied on a wide range of existing surfaces (mortar, cement, traditional waterproof sheeting, ceramics, wood etc.), using a few simple steps.
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface.
3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Isolation layer
The polystyrene panels are positioned directly over the membrane, taking care to ensure they are correctly overlapped and fitted.
5. Ballast layer
To ensure correct positioning of polystyrene panels these should be ballasted with, for example, dry aggregates.
Fifth facade
Our liquid and continuous waterproofing systems provide the ideal solution for ensuring continuity with the other vertical facades usually produced using continuous mortar, offering both functionality and a consistent aesthetic finish.
1. Surface preparation
The procedure will consist of first ensuring correct preparation to ensure a good initial appearance of the surface, typically made of concrete, bearing in mind that the final aesthetic finish is a key element of the process.
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface
3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Finish layer
The TECNOPOL finish consists of an aliphatic polyurethane resin, highly resistant to UV rays and hard wearing (can be walked on), which is applied using either airless equipment or a roller.

Garden area roofs & flooring
1. Support preparation
Finishes designed for garden area roofs and flooring may be applied on a wide range of existing surfaces (mortar, cement, traditional waterproof sheeting, ceramics, wood etc.)
2. Primer
First apply a coat of primer resin to ensure maximum adhesion to the surface.
3. Waterproofing membrane
Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used.
4. Finish layer
The company responsible for the design and style of the gardened roof area will need to decide on the various additional coats required for this type of finish.
