Project Overview and Location

This project took place on Rue Muriac in Montréal, Québec, as part of a residential renovation Montreal homeowners commonly undertake when updating bathrooms and service spaces.

Based on the site notes and takeoff, the work centered around a compact room (noted as approximately 8′ x 9′) and included:

• Drywall installation (bathroom): ~374 sq. ft.
• Joint plastering (bathroom): ~374 sq. ft.
• Primer (bathroom + first-level local areas): ~374 sq. ft.
• Painting (bathroom + first-level local areas): ~598 sq. ft.
• Masking / protection: ~254 sq. ft.
• Localized plaster repairs noted for other areas (small ceiling/wall repairs)

The photos show the bathroom/compact room portion in detail: framing and spray foam insulation in place, a partially open ceiling early on, then full board installation, joint compound stages, and finally a crisp white finish.

Project Scope Overview

As a dedicated drywall contractor Montreal homeowners call when they want clean, durable finishes, our scope here was focused and measurable. The project scope—based on the provided worksheet and the photo set—included:

Protection and site preparation

• Masking and floor/wall protection (~254 sq. ft.) using jobsite protection materials (including protective board and plastic sheeting).

Gypsum board installation (bathroom)

• Gypsum board installation using 1/2″ x 4′ x 8′ UltraLight Mold Tough drywall (14 sheets noted).
• Fastening with #6 x 2″ flat head drywall screws.
• Installing metal corner bead trim where required for clean outside corners and edges.

Plastering / joint finishing (bathroom)

• Taping and joint reinforcement with ADFORS FibaFuse drywall tape.
• Joint compound build-up using setting-type products (including Sheetrock 90 and Durabond 90) and finishing compound (CGC Sheetrock Lite).

Primer and paint application

• Priming with Sherwin-Williams ProMar 200 HP Primer.
• Painting using:
  • SW ProMar 400 Flat (ceiling paint)
  • SW ProMar 200 Acrylic Latex (wall paint)
  • SW Duration Home Bathroom Enamel (bathroom-rated enamel; 2 gallons noted)

Clean-up

• Jobsite containment, debris control, and disposal using contractor-grade clean-up bags.

This is the core of what most clients mean when they ask for “drywall, plastering services Montreal, and painting”—but the difference is in how the steps are sequenced and detailed.

Drywall Installation Process

The photos show the room in its open stage: exposed studs, spray foam insulation in the wall cavities, electrical rough-ins visible, and plumbing penetrations coming up through the floor. This is where the success of a drywall installation is decided—before the first screw goes in.

Board selection for a bathroom environment

For this project, the specified board was UltraLight Mold Tough drywall in 1/2″ thickness. In a bathroom or moisture-prone room, using a mold- and moisture-resistant gypsum board is a practical choice for durability. Montréal homes deal with large seasonal humidity changes, and bathrooms amplify that stress.

This is a key detail for drywall installation Montreal projects: the “right” board isn’t always standard white drywall—especially when the space will see humidity.

Layout and planning before hanging

Even in a compact room, the layout matters:

• Minimizing unnecessary seams (fewer joints = fewer potential crack lines)
• Planning around penetrations (plumbing stub-ups and electrical boxes)
• Keeping corners straight and reinforcing outside edges

One of your photos shows a close-up of measurement on a sheet—exactly the kind of precision step that prevents gaps, misaligned seams, and time-consuming patchwork later.

Ceiling first, then walls

The progression visible in the photos shows ceiling boarding underway first (with a portion still open early on). Hanging the ceiling first is common practice because:

• Wall sheets can help support ceiling edges
• It keeps corner geometry clean for later finishing
• It reduces the chance of edge cracking at the wall-to-ceiling junction

Detailing around visible features

A major design/structural feature in this space is the exposed wood beam running across the ceiling area (clearly visible in every stage, from open framing to final paint). That beam creates two challenges for drywall work:

1. Tight, clean drywall-to-wood transitions
2. Straight lines that stay straight after mud, primer, and paint

The final photos show the beam left exposed and contrasted against clean white surfaces—meaning the drywall edges and paint cut lines had to be controlled and consistent.

Fastening and corner reinforcement

The material list includes metal corner bead trim (corner bead is what gives outside corners their straight, impact-resistant edge). In tighter rooms—especially bathrooms where installers, plumbers, and cabinet crews work close to walls—strong corners reduce chipping and edge damage.

Plastering & Skim Coating Details

In Montréal, “plastering” on renovation projects often refers to drywall joint finishing: taping, embedding, building coats, and smoothing to a paint-ready surface. Your photos show this stage clearly: green boards with white compound at seams, corners, and screw heads.

Joint reinforcement with FibaFuse

The worksheet specifies ADFORS FibaFuse Drywall Tape. FibaFuse is a fiberglass mat tape used to reinforce joints and reduce the risk of future cracking compared to basic paper tape in some conditions.

In a bathroom environment (humidity cycling), strong joint reinforcement is a smart choice—especially at long seams and inside corners.

Setting-type compounds for strength and control

This project also included setting-type joint compounds:

• Durabond 90
• Sheetrock 90

Setting compounds cure chemically (rather than only drying by evaporation). They’re commonly used to:

• Build a stronger base coat
• Reduce shrinkage compared to some air-drying compounds
• Improve durability in high-traffic or higher-stress areas

This approach makes sense for a small bathroom room where corners, seams, and penetrations are numerous and where long-term crack resistance matters.

Finishing coats for smoothness

After structural coats, the finishing stage needs to sand and feather cleanly. The listed CGC Sheetrock Lite Drywall Compound is consistent with that role—lighter, easier to sand, and ideal for final smoothing.

When people search for a plaster skim coat in Montréal, what they usually want is that final “disappearing seam” look. On this project, the photos show:

• Wide feathered joints (horizontal and vertical seams)
• Clean inside corners
• Full screw-head spotting across the walls and ceiling
• Attention around the window opening and beam transitions

A smooth paint finish starts here. If joint finishing is rushed, paint will highlight every ridge and repair.

Primer Application & Surface Preparation

Once joints are finished, priming is not just a formality—it’s a quality-control checkpoint.

For this project, the primer specified was Sherwin-Williams ProMar 200 HP Primer (2 gallons noted). Primer has three critical roles on fresh drywall:

1. Seals porosity differences between paper face and joint compound
2. Reduces flashing, where patches show through paint at certain angles
3. Reveals surface imperfections early—before finish paint makes them permanent

This is where experienced plastering services Montreal teams slow down and inspect. Under raking light, small ridges, pinholes, and tool lines become visible. Correcting them after primer is faster and cleaner than after finish coats.

Because the job included primer and paint application across the bathroom and additional first-level areas, consistent primer coverage was necessary to keep sheen uniform across all repaired and newly boarded surfaces.

Interior Painting Process

The final photos show exactly what a homeowner wants at the end of a renovation phase: clean, bright walls and ceiling with crisp edges and a uniform finish.

The specified coatings on this job were:

• SW ProMar 400 Flat Paint (Ceiling)
• SW ProMar 200 Acrylic Latex (Walls)
• SW Duration Home Bathroom Enamel (Bathroom enamel, 2 gallons)

Ceiling paint selection and finish

Flat ceiling paint is commonly used to reduce glare and hide minor ceiling texture variations. In a small room with a window (and strong natural light), this matters—a ceiling sheen can highlight joint lines.

Wall paint for consistent coverage

Acrylic latex wall paint is a reliable choice for most interior spaces, and it pairs well with properly primed fresh drywall.

Bathroom enamel for moisture durability

Bathrooms are tougher than standard rooms. Even with good ventilation, moisture spikes happen. That’s why the bathroom enamel selection is important: it’s designed to stand up better to humidity and cleaning than a standard flat wall paint.

From an interior painting Montreal perspective, this is a practical move. Montréal winters can drive indoor humidity down, and summers can push it up—those swings expand and contract materials. Durable coatings help surfaces stay clean and stable longer.

Cut lines and detailing around features

The space includes several details that require careful paint handling:

• The exposed beam
• Window returns and trim transitions
• A boxed-out vertical bulkhead/chase (visible in the final photos)
• Multiple mechanical/electrical penetrations

The final photos show straight lines, clean corners, and even sheen—signs that the paint stages were not rushed.

Challenges & Solutions on This Project

Every renovation has constraints. This one had several that are common in Montréal homes, and the photos make them easy to identify.

Challenge: Tight working space

A compact room forces efficient sequencing—drywall handling, ladders, and finishing work all happen within a small footprint.

Solution: Careful board planning, fewer unnecessary joints, and controlled staging of tools and materials.

Challenge: Multiple penetrations and rough-ins

The floor and wall show plumbing stub-outs and electrical boxes that require precise cutting and later clean finishing.

Solution: Accurate measurement (as shown in the drywall measurement photo), tight cutouts, and disciplined finishing around penetrations so plates and fixtures sit flat later.

Challenge: Exposed beam transitions

A visible beam means every imperfection is framed by contrast.

Solution: Clean drywall edges at the beam interface, controlled plaster build-up, and careful cut-in work during painting.

Challenge: Moisture considerations in a bathroom

Bathrooms amplify humidity and are less forgiving when standard drywall and standard paint systems are used.

Solution: Mold-resistant drywall and bathroom-rated enamel, supported by proper priming and thorough joint finishing.

Challenge: Cleanliness during renovation

Drywall work creates dust, and paint demands protection of adjacent surfaces.

Solution: Masking and protection materials included Ram Board, plastic sheeting, and painter’s tape, supported by proper debris disposal (clean-up bags listed in the materials).

Quality Control & Finishing Standards

For homeowners, “quality control” should translate into visible and lasting results:

• Walls that look flat under natural light
• Corners that are straight and impact-resistant
• No visible seam lines after painting
• Clean edges where materials meet (beam-to-drywall, window returns, bulkheads)

On this project, quality control came from process:

1. Confirming board fastening and alignment before finishing
2. Using reinforced tape and appropriate compounds for joint strength
3. Building and feathering joints so they disappear under paint
4. Priming to lock down porosity and reveal imperfections
5. Applying finish coats suited to ceilings, walls, and bathroom conditions

These standards matter in Montréal homes because renovations often connect new work to older assemblies. Temperature and humidity cycles can expose weak joints and poor paint prep quickly.

Before & After Results

• Exposed studs and insulation
• Electrical rough-ins visible
• Ceiling partially open
• A prominent wood beam spanning the room

This is the stage where precision matters most—because once drywall goes up, the structure is hidden, and any missed planning becomes a finishing problem.

During (drywall installation and joint finishing)

• Mold-resistant green drywall on walls and ceiling
• Taped seams and coated joints
• Screw head spotting across the field
• Progressive build-up at corners and transitions

These photos show a methodical finishing approach—exactly what you want before primer.

After (primed and painted finish)

• Bright, uniform white walls and ceiling
• Clean edges and corners
• The exposed beam preserved as an architectural feature
• Bulkhead/chase finished cleanly, ready for the next renovation stages (fixtures, trim, etc.)

The result is a clean, modern shell that’s ready for final bathroom fit-out without needing additional patchwork.

Why Professional Drywall & Painting Matters

Many renovation problems show up late—often after the bathroom is nearly complete:

• Hairline cracks along seams
• Uneven corners
• Paint flashing over patches
• Rough walls that don’t look “high-end”

A professional Montreal renovation contractor (or specialized finishing contractor working within a GC team) prevents these issues by treating drywall, plastering, and painting as one connected system—not separate tasks.

This is also why drywall repair Montreal calls often come from renovations where the finishing stage was rushed. It’s easier and more cost-effective to do it correctly the first time than to fix it after tile, cabinetry, and lighting are installed.
