Painted MDF furniture looks similar across a wide price range at first glance, but the differences are in the board grade, the spray schedule and the edge detailing, none of which are obvious from a showroom sample alone.
Understanding these variables is the difference between comparing two genuinely equivalent quotes and comparing one that's quietly cut corners.
Board grade and thickness
Moisture-resistant grades cost more than standard MDF, and within moisture-resistant grades there's a range of density and consistency — a cheaper board can be more prone to swelling at a poorly sealed edge even before the finish is applied.
Thicker boards used for larger doors or panels cost more per sheet and are heavier to handle and hang correctly, which affects both material and labour cost.
Door profile and machining
A flat slab door is the cheapest to produce; anything with a routed shaker frame, a raised panel or a curved edge adds machining time and increases the risk of chipping during production, which in turn affects the finishing time needed to make it good.
More complex profiles also have more edges and internal corners that need sealing and spraying evenly, which adds to the finishing labour beyond the machining cost alone.
Spray schedule and edge sealing
A proper spray schedule for MR-MDF furniture includes sealing primer coats, at least one fill-and-sand stage, and multiple top coats, particularly on edges where the exposed fibre is most absorbent — skipping stages here is invisible until the finish fails or an edge swells.
A quote that's noticeably cheaper for what looks like the same specification has often reduced the number of coats or the sanding stages between them, which shows up later as a less durable or less even finish rather than at handover.
What a cheaper competing quote has usually substituted
The most common corners cut are a lower board grade, fewer primer or top coats, and reduced edge sealing around sink and appliance cut-outs — all of which look identical on installation day and only show themselves once the furniture is in daily use.
- Board grade
- Standard vs premium moisture-resistant density
- Door profile
- Flat slab vs shaker frame or raised panel — more machining and finishing
- Spray coats
- Full primer/fill/top-coat schedule vs a reduced number of passes
- Edge sealing
- Full sealed edges at cut-outs vs minimal treatment
Common questions
Why is one painted MDF kitchen quote cheaper than another for the same design?+
Almost always board grade, the number of spray coats, or how thoroughly edges are sealed around sink and appliance cut-outs, rather than a different amount of material used.
Does door profile really change the price that much?+
Yes — a shaker or raised-panel door has more edges and machining steps than a flat slab, and each of those edges needs the same careful sealing and spraying, which adds labour cost on top of the extra machining.
How can I check the spray schedule on a quote before committing?+
Ask how many primer, filler and top coats are included and whether edges around wet areas get additional sealing. A specific answer with a stated number of coats is a good sign; a vague answer usually means it hasn't been thought through.
