Dutch paint vocabulary — what goes on walls, wood, radiators, and outdoor work
Part of: Klussen
At a Dutch DIY shop, verf means paint, but it is not one product. The first question is always: what are you painting, and is it inside or outside? Buying a colour first and working backwards is how people end up putting wall paint on a radiator or indoor lacquer on an exterior window frame.
| What you are painting | Ask for | English | The important extra step |
|---|---|---|---|
| Plastered or previously painted wall | Muurverf | wall paint; often called “latex” | Use voorstrijk first on new or very absorbent walls |
| Interior door, skirting board, window frame, or furniture | Grondverf + binnenlak | primer + interior lacquer | Sand lightly between coats when the product instructions say to |
| Exterior door, window frame, or timber trim | Exterior primer/undercoat + buitenlak | exterior paint system | Use products intended to work together; do not paint in rain, mist, or strong sun |
| Radiator or heating pipe | Radiatorlak | heat-resistant radiator paint | Do not substitute wall paint or ordinary interior lacquer |
| Exterior wood where you want to see the grain | Beits or houtolie | stain or wood oil | These are different from a solid lacquer layer |
| Rusting metal | Metaalprimer or menie | metal primer / anti-rust primer | Remove loose rust and use a compatible finish coat |
The word lak means a hard-wearing paint or lacquer for wood, metal, and similar smooth surfaces. It is not the same as muurverf, which is formulated for walls and ceilings.
Dutch shops sell several products that English speakers may lazily call “primer.” They do different jobs.
| Dutch | Use it for | Do not confuse it with |
|---|---|---|
| Voorstrijk | New plaster, gypsum board, concrete, or an unevenly absorbent wall before mural paint | wood primer |
| Grondverf / grondlak | Bare wood, and the appropriate versions for metal or plastic, before lacquer | wall sealer |
| Fixerende voorstrijk | Powdery, chalky walls that rub off | a normal colour-changing primer |
| Vlekisolerende voorstrijk | Stains from nicotine, soot, or leaks | ordinary wall paint |
| Menie | Rust protection for suitable metal, or specialist protection products | a general-purpose primer |
For a new wall, voorstrijk reduces uneven absorption so the finish does not dry patchy or consume excessive wall paint. For bare wood, grondverf improves adhesion and gives you a surface that can be sanded smooth. Gamma’s wall-paint guide and preparation guide make the same distinction.
Binnenlak is interior lacquer. Water-based (watergedragen or acrylic) versions are the usual easy choice indoors: lower smell, faster drying, and less yellowing in pale colours. Buitenlak is made for weather, moisture, and UV exposure. Exterior work needs an exterior-rated system from primer through finish coat — an indoor product is not made durable by placing it outside.
Paint labels also name the sheen:
For exterior wood, beits is often the better option for softwood such as the vuren, grenen, or Douglas discussed in Hout. Unlike lacquer, it soaks into the wood rather than forming one solid layer over it. That can make maintenance easier when the wood moves with changing weather. Gamma’s comparison of lacquer, stain, and oil is a useful starting point.
A radiator needs radiatorlak, also sold as radiatorverf. It is designed to cope with repeated warming and cooling, and is available in white and other colours. Turn the heating off and let the radiator cool before painting. Read the tin for its temperature limit, drying time, and whether it is suitable for metal, because these vary by product.
At Gamma, Karwei, Praxis, and paint specialists, common names include Flexa, Histor, Sigma Coatings, Sikkens, and Wijzonol, alongside the shop’s own brand. The expensive option is not automatically necessary for a low-wear spare-room wall, but do not mix an exterior primer from one system with an unrelated finish coat just because both are the right colour. Read the label and follow the system it recommends.
RAL and NCS are standard colour languages. They let you tell a painter, shop, architect, or landlord exactly which shade you mean without relying on “warm white” or a photo that looks different on every screen.
RAL is the simpler code you will see most often in DIY shops and construction. The familiar RAL Classic system uses four digits: RAL 9010, for example. The first digit indicates a broad colour family — 1 yellow, 3 red, 5 blue, 7 grey, 8 brown, and 9 white or black — but the remaining digits are identifiers, not a recipe you can decode. RAL is especially common for window frames, doors, metalwork, and standard building colours. RAL’s own guide explains the different RAL collections.
NCS (Natural Colour System) is more precise and more common in interior design. A code such as NCS S 1040-R20B describes what the colour looks like: 10 is blackness, 40 is chromaticness (how vivid it is), and R20B means red with 20% blue. Neutral shades end in -N: NCS S 0500-N is an almost-white neutral with 5% blackness and no chromatic colour. NCS’s explanation of the system is useful if you want to read a full code.
A colour code identifies the shade, not the exact final appearance. Gloss level, surface texture, paint brand, light direction, and surrounding colours all change what your eye sees. Bring the code, a physical sample, or a removable piece of the old material when possible; a phone photograph is a poor colour reference under shop lighting.
P plus a higher number means a finer gritThe reliable order is: clean and degrease, repair, sand where needed, remove dust, apply the right primer if needed, then apply the finish coat. The exact drying and recoating times belong on the tin — temperature and humidity change them.
Do not paint outside in rain, mist, or full hot sun. Many exterior products specify conditions around 10–25°C and limited humidity, but the tin is the authority for that paint. Weather affects both drying and how long the coating lasts. Histor’s current advice is a good reminder to check the product rather than trust a generic rule.
Do not rinse brushes, rollers, or paint down the sink, even when the product is water-based. Keep usable leftovers in the sealed tin and take paint, primer, and related liquid waste to the milieustraat (municipal recycling centre). Gamma also advises against washing tools under the tap. See its disposal guidance.
