Video Summary - Peintures MATHYS, tests et avis

Product reviewed

Mathys (Rust-Oleum group) ceiling/wall paint—specifically discussed as an “ultra clean / matte” type paint. The reviewer initially treats it like a ceiling paint, but later argues it’s better suited for interior walls.

Key features mentioned

Open time / drying claim
- Manufacturer/technical data emphasizes:
  - Touch-dry in 2 hours
  - Completely dry in 2 hours
- The reviewer finds this notably slower than typical acrylics (often around ~30 minutes).
Mixing & application
- Must be well mixed before use.
- Perfect brush glide; paint doesn’t run.
Finish / appearance
- Very white
- Final look described as semi-velvet / almost velvet / almost matte
- Not truly “ceiling matte” in practice.
- Labeled washable, which the reviewer says fits the observed sheen/finish.
Coverage (reported vs observed)
- Technical sheet: about 8 m² per liter (ceiling).
- Reviewer’s tests: about ~6 m² per liter.
- Porous/unsealed surfaces reduce performance, increasing consumption.

Pros (what works well)

Consistency
- The paint has the “right” viscosity and is easy to handle with roller/brush.
No need to dilute
- Reviewer says it didn’t require thinning to apply well.
Open time
- Useful workability for larger ceiling areas; reviewer mentions covering up to ~20 m² while working.
Value for money (sometimes)
- Described as a strong entry-level professional paint, with better affordability than basic DIY-store paints.
Odor / applicator comfort
- Smell is light and not unpleasant during application, though it becomes more noticeable as it dries over larger areas.

Cons (main issues / complaints)

Opacity / hiding power is the biggest problem
- First coat may show the paint’s “composition” due to weak hiding.
- If you rely on one coat (or touch-ups), results can look uneven, especially under varying sunlight or grazing light.
- Reviewer suggests that adding extra layers can sometimes worsen the final look depending on lighting.
Sheen and defect highlighting
- Despite being called “matte,” the paint produces a specular sheen.
- Technical sheet reference: up to ~3% at around 80° (reviewer says real-world sheen is higher).
- Sheen reveals roller imperfections and ceiling defects (e.g., plaster drips/holes).
Coverage mismatch
- Advertised 8 m²/L vs reviewer’s observation of ~6 m²/L.
- Reviewer partially penalizes the product based on this gap.
Use-case mismatch (labeling/accuracy)
- Core criticism: the can says “matte”, and the reviewer assumed ceiling suitability.
- Technical sheet clarification: it’s “matte interior wall paint.”
- Strong warning from the reviewer: don’t use it as a ceiling paint unless it truly matches the ceiling specification.
Smell (after application)
- Not bad, but noticeable in bedrooms/hallways once drying progresses, leading to a rating penalty.

Comparisons mentioned

Versus other ceiling paint (Levis)
- Reviewer says Levis disappointed them compared to Mathys.
Versus competitors generally
- The open time/drying claim stands out versus competitors.
- Reviewer suspects the wording may be “games,” but still notes the practical difference.
Versus basic DIY-store “basic paints”
- Reviewer claims Mathys is dramatically better (at least in avoiding messy-looking results on walls/ceilings).
Positioning vs entry-level pro paints
- Reviewer places Mathys entry-level alongside Comptoir de l’Ours or Théodore.

Ratings / numerical scores included

Drying / open time
- No explicit star rating, but key claims are:
  - Touch-dry in 2 hours
  - Fully dry in 2 hours
Opacity / finish / odor / value
- Star ratings are described inconsistently across segments.
- What’s explicit:
  - Coverage / consumption: 1 star (using ~1 liter per ~6 m² vs expected)
  - Consistency / glide / whiteness / smell “tolerable”: multiple sections award 2 stars
  - Value for money: 1 star in one part due to overall opacity/application shortcomings
Dry performance numbers (sheen)
- Technical sheet reference: up to ~3% at about 80°.
- Reviewer claims the actual sheen is higher.

User experience (as described)

Painter-type experience emphasizes:
- Easy brushing/rolling, good glide, and no running
- Works well over extended working time
The final look suffers on ceilings because of:
- Sheen
- Poor hiding
- Especially noticeable when using one coat and when the ceiling isn’t perfectly prepared.

Unique points mentioned (consolidated list)

Mathys brand background and distribution (Belgium; founded 1845; Rust-Oleum acquisition).
Drying/open time claim: touch-dry and complete dry in ~2 hours.
Technical sheets are emphasized as a key resource for professional paints.
Coverage advertised ~8 m²/L vs observed ~6 m²/L; porous surfaces can consume more.
Requires mixing; brush/roller application is smooth; doesn’t run.
Whiteness and consistency are praised.
Opacity is inadequate for touch-ups / one-coat use; lighting affects perceived finish.
Smell is mild during application but noticeable as it dries; not intolerable.
Finish is not truly “matte ceiling” (semi-velvet appearance with measurable sheen).
Sheen highlights roller imperfections and surface defects.
“Washable” likely correlates with the sheen/finish behavior.
Major warning: labeled “matte,” but technically interior wall paint, not ceiling paint.
Overall positioning: good entry-level professional paint; better than DIY basics.
Comparisons include contrasts with Levis and mentions of Comptoir de l’Ours / Théodore.

Speakers / views

Single main reviewer/narrator provides essentially all opinions and testing observations (no clearly separated co-speakers).

Verdict / recommendation (based on the video)

Recommended as an entry-level professional paint for interior walls, but not recommended as a ceiling paint.

Main reasons:

Sheen and poor opacity/hiding power
Can expose defects and make one-coat touch-ups look bad, especially under grazing light

If buying for ceilings, the reviewer advises checking the technical sheet first and avoiding this “matte” product as a ceiling paint unless it truly matches the ceiling spec.
