A practical guide to ensure that you always choose the right primer
We are sure that it would no surprise you to hear us say that every project is different. The characteristics of each project are determined by the type of substrate to be treated, as well as its state, prevailing climate conditions (temperature and humidity) and the system to be used.
Based on our experience we can affirm that one of the most important steps to guarantee the system’s success is the primer, both in terms of choosing the right product and as regards its application. Carrying out this step correctly guarantees the success of the job and avoids the setbacks and problems that could arise in the future.
At the moment we have a range of 5 different kinds of primers that cover the wide range of substrates and conditions that you may have to deal with in your projects.
- PRIMER EP-1020. 100% solids epoxy based primer
- PRIMER EPw-1070. Water based epoxy primer
- PRIMER PU-1000. Polyurethane primer solvent based
- PRIMER PU-1050. Polyurethane primer 100% solids
- PRIMER PUc-1050. Polyurethane primer 100% solids for low temperatures
The following comparative table shows the main characteristics of our primers:

THE RIGHT CHOICE
THE DESMOPOL POLYURETHANE AND TECNOCOAT PURE POLYUREA SYSTEMS
(concrete, cement, etc.)
|5 -15ºC||PRIMER PUc-1050|
(metal, ceramic, laminate, asphalt, wood, etc.)
|3 - 35 ºC||PRIMER EPw-1070|
* Use only in DESMOPOL systems

The steps described below are for guidance purposes only; to ensure correct application we suggest you read carefully the technical specifications for the product, available on our web page.
Prepare the substrate correctly, in accordance with the procedures indicated in the technical specifications.
Mix the two components using a mechanical agitator for approximately 2 minutes.
Apply one or several coats using a roller or suitable airless equipment until the required thickness is achieved. Wait until touch dry between each coat and do not exceed, in any case, the maximum re-application time. If this time is exceeded, the substrate preparation must be repeated and the process started again.
Wait until the drying time has elapsed before continuing to apply the chosen system.
EXCELLENT REPAIR CEMENT
A “trick” to achieve an excellent and extremely hard repair cement without using any water in the mixture, which avoids retraction and makes it really quick drying, is to mix 1 part of PRIMER EP-1020 resin with three parts of calcium carbonate CaCO3.
