Choosing the right building materials is one of the most important decisions in any construction or renovation project. Materials influence not only how a space looks when work is completed, but also how well walls, floors, facades and wet areas perform over time.
The best results rarely come from selecting individual products in isolation. They come from matching the substrate, the environment and the final finish with compatible construction materials that work as a complete system.
At Eder Trade, construction solutions cover waterproofing and concrete protection, tile installation, thermal insulation, surface preparation, interior and exterior painting, and protection for different surfaces. This allows a project to be planned by application rather than by buying unrelated products.
Why Surface Preparation Comes First
Before applying paint, tile adhesive, waterproofing or insulation, the existing surface must be checked carefully. Dust, weak plaster, cracks, moisture, old coatings and highly absorbent substrates can reduce adhesion and shorten the lifespan of the finished system.
For porous or dusty surfaces, UNIGRUND TOP can be used as a deep-penetrating primer, while smooth or dense concrete may require a bonding primer such as BETONKONTAKT. Where walls contain holes, cracks or uneven areas, fillers and smoothing compounds should be applied before priming and finishing. Surface preparation is therefore the foundation for reliable renovation work.


Waterproofing Materials for Wet and Exposed Areas
Waterproofing materials are particularly important in bathrooms, terraces, balconies, roofs and foundations. The correct waterproofing system depends on the location, movement of the substrate and whether the surface will remain exposed or be covered with tiles.
HIDROBLOCK VH 2K is intended for bathrooms and internal wet areas before tiling, while HIDROBLOCK FLEX 2K is designed for balconies and terraces requiring flexible undertile waterproofing. Critical corners, drains and wall-floor junctions can be reinforced with FIXBAND waterproof tape.
This system-based approach is more reliable than depending on tiles and grout alone to stop moisture.
Choosing the Right Tile Installation Materials
Tile installation depends on more than the tile itself. The substrate, tile size, moisture exposure and project location should determine the adhesive and grout system.
For standard ceramic tiles on stable interior surfaces, MrFIX EXTRA 300 is one available option. For larger tiles or more demanding applications, FLEX 500 or FINAL KERAMIK can provide higher-performance bonding.
In bathrooms, showers and terraces, the adhesive should be combined with an appropriate waterproofing membrane below the tiles. Compatible grout such as NANOFILL or FINAL FUGAFIX then completes the joint system.


Thermal Insulation and Exterior Facade Systems
Thermal insulation materials should be treated as part of a complete facade system rather than simply choosing an EPS board. A professional ETICS build-up can include surface preparation, adhesive, insulation boards, fixings, reinforcing mesh, primer and the final decorative coating.
Eder Trade offers system ranges including REDETHERM, FINALIT and TERMOPROOF. For facade preparation and finishing, UNIGRUND TOP or X10 Universelle Grund can prepare suitable substrates, while WEISSCRYL TOP and BRAVO FAS provide exterior coating options.
Selecting compatible layers is important because exterior walls face rain, sunlight, humidity and temperature changes.
Interior Paints and Finishing Materials
Interior renovation often ends with paint, but the final coat performs best when the wall has already been repaired, smoothed and primed correctly.
BRAVO and UNIWEISS TOP suit general interior painting, while KEMOPOL PLUS and PROFIWEISS TOP target standard residential applications. For areas requiring stronger washability or additional protection, LATEX STRONG, KEMOPOL PROTECT and KEMOPOL PREMIUM PROTECT are more specialized choices.
The correct interior paint should therefore be selected according to the room, traffic level, moisture conditions and desired finish.



How to Choose Building Materials for Your Project
When comparing building materials for construction and renovation, price should not be the only criterion. Consider the substrate, indoor or outdoor exposure, moisture, temperature changes, required durability and compatibility with other products in the system.
A cheaper choice can become more expensive if poor compatibility leads to peeling paint, loose tiles, moisture damage or premature repairs.
Eder Trade supplies paints, coatings, adhesives and professional construction materials from Chromos Svjetlost, MrFix and Reder, together with technical support for product selection and quantity planning.
Whether the project involves a bathroom renovation, facade, thermal insulation or interior finishing, choosing renovation materials as a coordinated system can help achieve a more durable, consistent and professional result.
