Hi I'm Mark Tomassino
owner of Mark's Quality Painting
With over 12 years of hands-on experience, we provide Drywall Repair & Installation across Eastern Ontario with a focus on preparation, craftsmanship, and finishes that last. Homeowners trust us because we take the time to do the work properly — without rushing or cutting corners.
Below is the proven process we use to apply our drywall process
Drywall done properly makes all the difference once paint goes on.
Our process emphasizes correct preparation, multiple finishing passes where needed, and careful sanding so the final result looks clean once painted.
Cleanup is included — not left to the homeowner.
Remove or Repair Damaged Drywall
Before any new drywall or finishing work begins, we carefully assess the area and remove or repair damaged drywall as needed. This includes sections affected by cracks, holes, water damage, previous poor repairs, or loose material that could compromise the final finish.
Damaged drywall is never covered or patched without proper preparation. Any unstable or failing sections are cut back cleanly to ensure repairs are solid and long-lasting — not temporary fixes that show through paint later.
Why this step matters:
Prevents future cracking or failure
Ensures repairs bond correctly
Creates a stable base for new drywall and finishing
Eliminates visible flaws once painted
This first step sets the foundation for clean, professional drywall results and is never skipped or rushed.
Reinforce and Install New Drywall
(When Needed)
Once damaged areas are removed or properly prepared, we reinforce the framing as needed and install new drywall to restore the surface. This includes adding backing where required, securing panels correctly, and ensuring everything is level, tight, and properly supported.
Drywall is installed with correct fastening patterns to prevent movement, sagging, or future cracks. We take the time to make sure seams align properly and edges are secure, creating a solid, stable surface before any finishing work begins.
Why this step matters:
Prevents shifting, popping, or cracking over time
Ensures drywall panels sit flat and secure
Creates clean seams that are easier to finish smoothly
Provides long-term durability, not short-term fixes
Proper installation and reinforcement are critical for a professional finish and ensure the drywall holds up once plaster, sanding, and paint are applied.
Plaster Joints, Seams, and Repaired Areas
After new drywall is installed and secured, we apply plaster to all joints, seams, fastener areas, and repairs. This process builds a smooth transition between panels and repaired sections so the surface looks continuous — not patched.
Multiple passes are applied where needed, allowing proper drying between coats. This ensures strong joints, minimizes shrinkage, and prevents seams or repairs from showing through once the surface is painted.
Why this step matters:
Creates seamless transitions between drywall panels
Strengthens joints and repaired areas
Prevents visible seams and patch lines
Builds a smooth, uniform surface for sanding
Plastering is done with care and precision, forming the foundation for a clean, professional finish before sanding begins.
Protect the Space & Contain Dust
Before sanding begins, we properly plastic off the work area to contain dust and prevent it from spreading through the rest of the home. Floors, doorways, and nearby surfaces are protected so drywall dust stays where it belongs.
Drywall sanding creates fine dust that can travel easily if not controlled. Taking the time to properly isolate the space keeps your home cleaner and avoids unnecessary cleanup later.
Why this step matters:
Keeps drywall dust out of the rest of the house
Protects floors, furniture, and nearby rooms
Makes cleanup faster and more effective
Shows respect for your home
This step is often skipped — we don’t.
Sanding for a Smooth, Even Finish
Once the plaster has fully dried, we sand the surface to achieve a smooth, even finish. This step removes excess compound, blends seams and repairs, and eliminates ridges or imperfections so the drywall surface looks flat and uniform.
Sanding is done carefully to avoid over-sanding while ensuring all joints and repaired areas are properly feathered. The goal is a surface that looks clean and consistent under all lighting conditions — especially once paint is applied.
Why this step matters:
Removes visible seams and ridges
Ensures a flat, uniform surface
Prevents imperfections from showing through paint
Prepares the drywall for a professional paint finish
Proper sanding is what turns drywall repairs into invisible repairs and is essential for a high-quality final result.
Full Cleanup & Dust Removal
Once sanding is complete, we thoroughly clean the work area. This includes removing drywall dust, collecting debris, and leaving the space clean and ready for paint.
Too often, drywall or plaster work is left messy, forcing homeowners to deal with dust and cleanup themselves. We don’t leave that behind. Cleanup is part of the job, not an extra.
Why this step matters:
You’re not left cleaning drywall dust
Prevents dust from affecting paint finishes
Leaves the space ready for the next step
Delivers a professional, complete job
When we’re done, the area is clean — not something you have to deal with afterward.
Prime, Seal & Paint
Drywall repairs are always primed and sealed before painting.
Once the drywall work is complete and the area is clean, we apply a primer/sealer to the repaired or newly installed drywall. This step seals the surface, evens out porosity, and ensures the paint applies smoothly and consistently.
Drywall without proper priming can lead to flashing, uneven sheen, and visible repairs after painting. Using the correct primer prevents these issues and creates a uniform base for the finish coats.
After priming, we apply the finish paint to complete the space with a clean, professional result.
Why this step matters:
Seals new drywall and repairs
Prevents flashing and uneven paint appearance
Ensures proper paint adhesion
Delivers a consistent, professional finish
Priming isn’t an add-on — it’s part of doing drywall and paint work the right way.
