Renovation of flat roofs and terraces

The renovation of older flat roofs requires effective and hard wearing solutions. TECNOPOL continuous systems provide excellent results without the need to remove the existing paving or flooring surface. In addition, the nature of these finishes makes them ideal for use on older roofs which are hardly ever perfectly smooth or flat.

Where the renovation also requires thermal insulation we can provide one of the best systems on the market providing optimum results in terms of low heat conductivity.

Flat roof renovation

1 Surface preparation

Initially the floor will need to be cleaned down to remove all traces of the previous waterproofing material or loose pieces, and cracks and joins should be filled or repaired to ensure as flat a surface as possible.

tecnoband 100
Geotextile reinforcement band

A transversely deformable adhesive band, formed of a viscous-elastic layer coated on a nonwoven mesh. The nonwoven element allows adaptation to the support of the band and is highly recommended for specific applications of polyurea membranes Tecnocoat.

2 Primer

First apply a coat of primer resin to ensure maximum adhesion to the surface.

Primer PU-1000
Two-component, 100% solids, polyurethane resin as a primer

PRIMER PU-1050 is a two-component, low viscosity 100% solid resin. It has been specifically designed to increase bonding and improve the surface leveling prior to the pure polyurea TECNOCOAT or DESMOPOL systems. It can be applied on porous substrates such as concrete or mortar

3 Waterproofing membrane

Depending on the system chosen a membrane from either the DESMOPOL or TECNOCOAT range will be used. In the event of applying the DESMOPOL system on ceramic or brick surfaces it is recommended that the DESMOPLUS 1 LAYER additive is employed to make the membrane more resistant.

Membrana desmopol
Single component, polyurethane waterproofing membrane

DESMOPOL is a single component liquid made up of polyurethane, solvent-based, moisture-cured once catalyzed forms a continuous, seamless, solid and elastic, watertight, and waterproof membrane. Its properties make it an excellent choice to be applied on a multitude of substrates of new buildings and especially in refurbishments. It is applied manually, using a roller or brush, squeegee, and exceptionally, using specific spray equipment.

It has CE marking on the basis of a statement made DoP Declaration of Performance (DoP) conforms to the regulations UE305/2011.

Desmoplus 1 Layer
Additive for the application of DESMOPOL / DESMOPOL CB in just one coat

DESMOPLUS is an additive that gives to the single component polyurethane membrane DESMOPOL/DESMOPOL CB several properties to facilitate its application in one layer without bubbles inside, improve their physical and mechanical properties, and gives a fast dry time. It is suitable for the application of polyurethane membranes in low-temperature conditions or adverse weather conditions.

4 Finish layer

The TECNOPOL 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). TECNOTOP can also be supplied in practically any colour.

Tecnotop 2c
Two-component, aliphatic polyurethane solvent based resin suitable as a flooring and protection against UV rays

TECNOTOP 2C is a two-component aliphatic, colored, glossy, polyurethane solvent-based, resin for treatment, decoration, flooring and protection of our waterproofing liquid systems (TECNOCOAT y DESMOPOL) in front of UV rays. It has continuous finishing and forms a hard, strong, continuous film, with excellent adhesion and mechanical properties as its excellent resistance to abrasion and stress that make it resistant to weathering, extreme temperature. It is suitable for coating protection for car traffic.

1 Suport preparation

Initially the floor will need to be cleaned down to remove all traces of the previous waterproofing material or loose pieces, and cracks and joins should be filled or repaired to ensure as flat a surface as possible. It is also important to provide a clean and aesthetic appearance as the coats we will then apply are completely transparent. .
