Knowledge base

Technology before promise.

Practical explanation for real estate managers, companies and executive partners. The library is divided into sections, so that new articles can be added later in a clear manner.

New knowledge cluster

New construction: from design to demonstrable delivery.

8 in-depth guides for developers, contractors, designers and administrators on waterproofing, flooring, planning and quality assurance.

Start with the question at hand.

01 / Decide

Renovate or replace?

For managers who want to know when an existing roof structure is likely to be renovated.

Roof coating privately

9 minutes leestijd

Polyurea, fast-drying PU or silicone for a private flat roof?

A binding agent name does not yet select a reliable roofing system. Compare substrate, primer, details, water load, walkability and maintenance before selecting a technology.

When is a private flat roof suitable for coating?

Coating is especially interesting when the existing roof structure can be technically preserved. A visually reasonable roof is not automatically suitable for this.

Coating a flat roof or replacing the roof covering?

Coating can postpone demolition and replacement, but only if the existing structure is sufficiently healthy and repairable.

White roof coating for home, extension or large garage

White waterproofing can limit sun absorption and keep the roof surface cooler on sunny days. The comfort and energy effect remains building-specific.

What determines the price of roof coating per m²?

The number of square meters is only one price factor. Preparation, details, accessibility, recovery and system construction often determine a more important part of the project sum.

Fast-track roof renovation

Fast drying roof coating for a short or changeable weather window

A fast product can limit exposure between layers, but only a well-prepared and monitored implementation plan makes the renovation responsible.

When does a BROOF classification apply to an existing commercial roof?

In case of renovation, the actual existing roof structure must fall within the limits of the classification report. The same color coating alone is not sufficient for this.

What does BROOF(t1) mean for roof coating?

BROOF(t1) is a classification of external fire performance for a tested roof structure. The designation does not automatically apply to every surface or layer thickness.

What documentation is required for a professional roof coating system?

A business system selection requires more than a product sheet: performance, components, implementation and project registration must be aligned.

CE marking and ETA for liquid roof waterproofing

CE and ETA provide insight into performance, but do not independently choose the right system for an existing roof.

What is the difference between ETAG, EAD and ETA?

ETAG 005, a current EAD and a product-specific ETA are often confused. This article clarifies what each document does and does not prove.

Why a product certificate is not yet an approved roof structure

A technical document can contain reliable product performance without approving every combination of substrate, primer and roof construction.

Polyurea or silicone for a white commercial roof?

A fair Cool Roof choice is not about one binding agent, but about the substrate, primer, details, mechanical load, reflection, water load and demonstrable system documentation.

Coating or completely replacing the commercial roof?

The condition of roof covering, insulation, adhesion and details determines whether renovation is technically justified. A good choice therefore starts with examining the complete roof structure.

What does a white waterproof roof membrane do?

A white final layer can combine waterproofing and sun reflection, provided the existing roof structure is suitable and all details are part of the same controlled system.

Floors

Compare epoxy, PU and polyaspartic

The choice of an industrial floor should not be determined by the product name, but by the use of the space, the surface and the available implementation time.

How do you limit downtime during floor renovation?

A short business interruption is not only caused by fast material. Recording, preparation, logistics, phasing and commissioning must be coordinated in advance.

Why concrete damage must be repaired first

A protective coating cannot solve loose concrete, active reinforcement corrosion or moving structural cracks. Recovery starts with the cause of the damage.

Positive and negative water pressure explained

The direction from which water presses on a structure influences material choice, adhesion and detailing. This is especially important in basements and elevator pits.

Why corrosion returns on metal roofs

Simply painting over rust often leaves the real cause, contamination and vulnerable details intact. Sustainable recovery requires preparation and an appropriate layer structure.

What should be included in a technical delivery report?

Good reporting makes the system structure carried out verifiable, supports maintenance and prevents important project knowledge from disappearing after delivery.

Spraying or rolling latex in a commercial building?

The fastest application method is not automatically the fastest project route. Surface, shielding, details and use determine where airless really provides an advantage.

Can a company remain open during latex spraying?

Phased work can limit business downtime, but requires clear boundaries for access, ventilation, mist and recommissioning.

Waarom is een primer belangrijk bij dakcoating?

Een primer is geen verkoopaccessoire en ook niet altijd hetzelfde. De functie volgt uit ondergrond, porositeit, vocht, bestaande lagen en gekozen membraan.

Wanneer wordt geotextiel in een dakcoatingsysteem toegepast?

Geotextiel kan kritieke zones versterken, maar is geen willekeurige extra laag over ieder volledig dak. Detailtype, beweging en systeemdocumentatie bepalen de inzet.

Hoe wordt materiaalverbruik en laagdikte van dakcoating gecontroleerd?

Een witte dekking is geen bewijs van voldoende membraan. Oppervlak, materiaalhoeveelheid, werkvakken en systeemdocumentatie moeten samen kloppen.

Hoe lang duurt de renovatie van een bedrijfsdak van 1.000 m²?

De netto applicatiesnelheid is slechts één onderdeel. Reiniging, herstel, details, primer, weersvenster, logistiek en bedrijfscontinuïteit bepalen de werkelijke doorlooptijd.

No product advice without project data.

The knowledge base helps with orientation. A final choice requires substrate information, loads, application conditions and official documentation.
