What is DESMOPOL?

The DESMOPOL range of products are supplied in liquid format and produce even, elastic and completely waterproof membranes with properties which make them an excellent choice for all types of surface - whether new constructions or the renovation of large and small scale projects.

The DESMOPOL range of products is specially formulated for waterproofing all types of surfaces for new construction and rehabilitation purposes. DESMOPOL can be applied on both flat and inclined surfaces and its high resistance properties makes it ideal for regular pedestrian traffic.

DESMOPOL is a completely watertight and continuous membrane, without joins or overlaps and 100% adherent to the surface.

Application is simple and fast, producing excellent results. It can be applied manually, with a roller, squeegee, or air-less projection equipment.

DESMOPOL is a hard wearing and resistant system ideal for areas of intensive use such as gardens, storage deposits, public municipal areas, damp zones of all types, etc.

 

Advantages of DESMOPOL systems

  • Easy application.
  • Rapid curing even in winter.

  • High resistance to extreme temperatures (between-40 ºC and + 80 ºC ).
  • High resistance to abrasion and tension.
  • High elasticity.
  • The membrane is completely waterproof.
  • Allows vapor diffusion.

 

Main uses

  • Waterproofing roofing (flat, sloping) and patios (passable and not passable).

  • Waterproofing of metallic surfaces
  • Protection of polyurethane foam for thermal insulation.

 

 

How apply DESMOPOL?

1. Support

To apply DESMOPOL the support must be a continuous surface without crevices or hollows in order to obtain the maximum adhesion of the continuous system of polyurethane. Also the support must be clean, dry and free of pollutants like dust, oil, grease, paint and other superficial treatments. When in doubt it is recommended that you realize tests on the substrate.

2. Preparation of the support

CONCRETE SUBSTRATES

The substrate should be consistent as our membranes have adhesion strengths of up to 1.85 N/mm2 (MPa). If you are not certain of the strength you should inspect the substrate and, where possible, carry out tests to determine the tensile strength.

If there is a weak layer of cement on the substrate or it has an uneven surface you should prepare it mechanically (milling, sanding, shot-blasting).

If there are any cracks or small holes they should be filled in and compacted with the appropriate filling, made using our PRIMER EP-1020 product which is very hard and fast drying.

Specific areas, such as structural joints and perimeter flashings with walls, should be prepared using DESMOSEAL MASILLA-PU putty and/or TECNOBAND 100 (ask our technical department). When all the preliminary work to prepare the substrate has been completed you should clean the area, clearing away any debris or loose material.

METAL SURFACES

The surface should be cleaned by applying our DILUYENTE TEC-4U solvent to ensure fast evaporation and drying. In the areas with overlaps, or the finishes of mechanical roof elements, we recommend using TECNOBAND 100 and/or DESMOSEAL MASILLA-PU putty to absorb the mechanical loads that are generated in this type of roof (ask our technical department).

Please contact Tecnopol Sistemas technical department if you have any queries about other types of substrate (fiber cement, wood, asphalt, ...).

3. Priming

You should also apply one of our primers (see table a) to increase adhesion to the substrate and achieve a correct surface finish. It can be applied by brush, roller or an airless spray.

In the case of concrete surfaces, the concrete should have completed the 28-day curing process after casting. You should also check that the degree of moisture in the surface of the substrate does not exceed the maximum allowable level of the product.

Surfaces Porous (concrete) X X  
Surfaces Not porous (metal, ceramics, plates, asphalt, wood...)     X

TO CHECK THE PRIMER HAS DRIED, TOUCH IT WITH YOUR FINGERTIPS. THE DRYING TIME VARIES BETWEEN 1 TO 6 HOURS, DEPENDING ON THE PRIMER USED, THE AMBIENT TEMPERATURE, AND THE TEMPERATURE OF THE SUBSTRATE.

THE PRIMER LOSES ITS PROPERTIES 24 HOURS AFTER APPLICATION AND, THEREFORE, A MINIMUM LAYER MUST BE REAPPLIED. THIS KIND OF REAPPLICATION IS ALSO NECESSARY FOLLOWING RAIN.

 

4. Desmopol Membrane

DESMOPOL can be applied using a spray machine capable of producing a pressure of 280 bar (4,000 psi) or by hand, using a brush or a roller and a rubber rake. In both cases application must be consistent.

  • Drying tact time: 3 ~ 5 hours*
  • Pedestrian traffic resistance: 12 ~ 48 hours
  • Wheeled traffic resistance: top coat required
  • Repainting rank: 5 ~ 48 hours** / 3 ~ 24 h. (with D.ACELERADOR)

* In the case of low environmental temperatures, use DESMOPOL ACCELERADOR.

** If you want to apply a second coat of DESMOPOL and more than 48 hours (24h with DESMOPOL ACELERADOR) have elapsed since the first coat of DESMOPOL was applied, the surface should be sanded and cleaned, and a primer coat of PRIMER EPW-1070 applied.

5. Top Coat (optional)

After the DESMOPOL membrane has been applied a protective coat of TECNOTOP aliphatic polyurethane varnish (see table b) should be applied within 48 hours (24h with DESMOPOL ACELERADOR), to ensure the stability of the desired colour when there is no additional protection. TECNOTOP is also good for surfaces with heavy vehicle traffic, and essential for non-slip finishes and waterproofing of swimming pools, fountains, water tanks, aquariums, etc.

+ F.A.Q.S

What type of product is the Desmopol waterproofing membrane system?tourner

It is a liquid based pure polyurethane elastomer that produces a continuous, flexible and completely impermeable membrane.


Where can I apply Desmopol? tourner

On any type of flat surface without voids or cracks with prior conditioning of the surface to obtain the maximum adhesion of the system. As a continuous membrane, it provides a versatility of adapting to any irregular surface, even if curved or squared.


How must I apply Desmopol? tourner

Desmopol can be applied with an airless projection machine or with a roller.


Can I apply Desmopol on pavement or existing roofing? tourner

Yes, simply bear in mind the preparation of the surfaces, cleaning them of dust, oils or grease to be able to apply Desmopol correctly.


Does it create joints? tourner

The system Desmopol does not create joints as it is applied direct to the support, to the perimeter parapets, or to the singular points such as drains, corners or finished surfaces. Being a completely adherent membrane, it does not create interior air pockets. In these areas of parapets or points of water collection in drains, it is advisable to use a geotextile mesh casing.


What colors is Desmopol available in? tourner

It appears in a colors variety such as gray, brick-red, white or transparent. Although if it is preferred it is possible to apply aliphatic varnish specific with a wide scale of colors RAL on the surface.


How long does it take Desmopol to dry? tourner

Desmopol has a process of stability and drying of 8 hours approximately after application. Although this time can change perceptibly according to the grade of exterior environmental temperature (pg. 9 of the Desmopol catalog).


What to do in case of a leak? tourner

Desmopol failure is scarce, although in case of escape of moisture due to a mistake in the application of the waterproofing, or a break after application, since it is a completely adherent membrane to the support, the origin of the water, coincides with the area of the break, the location of this point is direct and therefore, it diminishes or limits to the minimum the repair work necessary.


When can I apply Desmopol? tourner

From support temperatures of 5ºC up to 35ºC the previous priming Tecnocoat Primer-PU can be applied. The relative humidity has to be less than 85%.


What other elements can I waterproof or protect? tourner

With Desmopol you can waterproof walls of concrete, deposits, cisterns or swimming pools with finished painting to be chosen.


What resistance does it have? tourner

It is a product with a traction resistance of 55 N/mm2.


Can I apply Desmopol on existing pavement? tourner

Yes, it is very advisable in rehabilitations of patios or roofs, passable or impassable, where the difficulty of work or the excess weight of the existing structure are two factors to be kept in mind.


What certifications does Desmopol have? tourner

Desmopol has the DITE 10/0121 certificate from theInstitute Eduardo Torroja with a useful life of 25 years.
