The Process of Drywall Finishing
November 4, 2024
Drywall finishing is the art of transforming raw drywall sheets into smooth, polished walls ready for paint or other finishes. At Saskatoon Drywallers, we know how important a quality finish is to the overall look of your space. If you’re planning a drywall installation, here’s an in-depth look at the drywall finishing process and what you can expect for a flawless outcome.
Understanding the Levels of Drywall Finishing
Drywall finishing consists of several stages, each adding to the final appearance. Industry standards define five distinct levels of drywall finish, from Level 0 to Level 5. Choosing the right level depends on your aesthetic preferences and the final surface treatment.
- Level 0: No finishing is done. This is just bare drywall installed, with no tape, mud, or sanding.
- Level 1: Basic taping and mudding for joints and screws. Often used in unfinished spaces like garages or attics.
- Level 2: Adds a second coat of joint compound over tape, suitable for areas that will be covered or tiled.
- Level 3: A third coat of compound, smoothed out, intended for walls that will receive a textured finish.
- Level 4: For smooth walls with a light or flat paint finish. Sanded to an even, seamless surface.
- Level 5: Adds a thin layer of joint compound over the entire surface for a pristine finish, ideal for high-end walls under bright lighting or glossy paint.
For most interior walls, Level 4 is a common standard, while Level 5 is popular in areas with high lighting or visible imperfections.
Step-by-Step Drywall Finishing Process
1. Preparation
Before any finishing work begins, proper preparation is crucial. At Saskatoon Drywallers, we ensure that drywall sheets are securely installed, with minimal gaps and firmly fastened screws. Small issues like rough edges or misalignments are corrected in this stage. Additionally, a clean workspace is essential, as dust or debris can interfere with the finishing process.
2. Taping the Seams
Taping involves covering the seams between drywall sheets with joint tape, usually made of paper or fiberglass mesh. Paper tape is more common and is applied over a thin layer of joint compound. Fiberglass tape is typically used for extra strength and durability. Taping strengthens the joints and prevents cracks as the building settles over time.
- Pro Tip: Paper tape is less prone to stretching or bubbling when applied correctly, which makes it a popular choice for walls and ceilings.
3. First Coat of Joint Compound (Mudding)
Once the tape is in place, the first layer of joint compound, also known as “mud,” is applied over the taped seams and screw indentations. The goal of this layer is to fill in gaps and create a smooth transition between drywall sheets.
- Drying Time: Joint compound usually needs at least 24 hours to dry, depending on room temperature and humidity levels. Faster-setting “hot mud” compounds are also available, which dry within hours and can be useful for time-sensitive projects.
4. Second Coat of Joint Compound
After the first layer has dried, a second coat of mud is applied. This coat is slightly wider than the first, extending beyond the edges of the tape to ensure a smooth blend with the surrounding drywall. At Saskatoon Drywallers, we pay careful attention to smoothing this layer, as each coat builds toward a flawless surface.
5. Third Coat and Sanding
A final coat of compound is applied, further smoothing any remaining unevenness. This coat provides a polished base and is especially important for Levels 4 and 5 finishes. After it dries, the surface is sanded carefully to remove any visible lines, bumps, or rough patches.
- Sanding Tip: Using fine-grit sandpaper (such as 220 grit) ensures that the finish is even without damaging the drywall surface.
6. Level 5 Skim Coat (Optional)
For high-end finishes, an additional skim coat of joint compound is applied across the entire wall or ceiling surface. This final layer provides an exceptionally smooth finish that prevents any minor imperfections from showing through paint, particularly under direct lighting. After the skim coat, a final round of sanding ensures that the surface is flawless.
7. Priming the Surface
Priming is a critical final step before painting. The primer seals the porous surface of the drywall and joint compound, creating a uniform base for paint application. It also enhances paint adhesion and ensures that the color appears consistent across the wall. Without a good primer, paint can appear uneven, especially in areas where joint compound is applied.
- Primer Selection: For high-moisture areas like bathrooms or basements, moisture-resistant or mold-inhibiting primers are ideal. For walls with a Level 5 finish, a high-build primer can further smooth the surface.
Common Challenges and How Professionals Overcome Them
Drywall finishing may look straightforward, but achieving a smooth and seamless look requires skill and experience. Here are some common challenges and how professionals at Saskatoon Drywallers handle them:
- Joint Compound Drying and Cracking: Inconsistent temperatures can cause joint compound to dry too quickly or unevenly, leading to cracks. We maintain a stable environment to prevent this and use compounds suitable for the specific space.
- Achieving Smooth Seams: Blending drywall sheets seamlessly requires precision. Our team uses the right tools, including wide drywall knives and sanders, to create a clean, level surface.
- Dust Control: Sanding drywall can create a lot of dust. Our professionals use dust barriers and vacuums to contain dust, keeping the work area clean and safe for residents.

When considering the comfort and health of your home, indoor air quality (IAQ) plays a critical role. While many people focus on ventilation systems, furniture, and cleaning products, drywall can significantly influence the air you breathe. At Saskatoon Drywallers , we understand the importance of using high-quality materials and proper installation techniques to ensure your drywall contributes positively to your home's environment. How Drywall Affects Indoor Air Quality 1. VOC Emissions Drywall itself is primarily composed of gypsum, a natural and safe mineral. However, the compounds used in joint compounds, adhesives, and finishes can emit volatile organic compounds (VOCs). These emissions may impact indoor air quality, especially in poorly ventilated spaces. Solutions: Choose low-VOC or zero-VOC drywall products and finishes. Opt for eco-friendly, water-based paints and primers. 2. Mold and Mildew Growth In regions like Saskatoon, where fluctuating humidity levels are common, moisture can infiltrate walls and lead to mold and mildew growth on drywall. Mold releases spores into the air, potentially causing respiratory issues and allergies. Prevention Tips: Install moisture-resistant or mold-resistant drywall in high-humidity areas like bathrooms and basements. Address leaks and condensation promptly to prevent moisture buildup. 3. Dust from Installation and Repairs Drywall installation and repairs often generate dust from cutting and sanding. This fine dust can linger in the air, irritating the respiratory system and exacerbating conditions like asthma. Mitigation Strategies: Use dust containment systems during installation. Clean up thoroughly with HEPA-filter vacuums to minimize airborne particles. 4. Air Purification Properties of Specialized Drywall Innovative drywall products, like air-purifying drywall, are now available. These options are designed to absorb and neutralize airborne toxins like formaldehyde, contributing to cleaner air indoors. Benefits of Air-Purifying Drywall: Reduces harmful chemical compounds in the air. Enhances overall indoor air quality, especially in newly constructed or renovated homes. The Role of Professional Installation Professional drywall installation ensures that the materials are properly handled and applied, reducing risks to IAQ. At Saskatoon Drywallers, we follow strict protocols to: Minimize dust and debris during installation. Seal joints and edges to prevent air leaks. Recommend and use high-quality, low-emission products. Long-Term Maintenance for Better IAQ Maintaining your drywall is just as important as its initial installation. To ensure your indoor air quality remains high: Inspect for Damage Regularly: Address cracks, holes, or water stains promptly. Control Humidity Levels: Use dehumidifiers and proper ventilation to prevent moisture issues. Repaint with Low-VOC Paints: When refreshing your walls, opt for eco-friendly options.

When it comes to giving your home or office a fresh new look, drywall installation is one of the most essential steps in the renovation process. However, the success of your drywall project largely depends on proper preparation. At Saskatoon Drywallers , we know that getting your walls ready for drywall installation is crucial to achieving a smooth, professional finish. In this article, we’ll walk you through everything you need to know about preparing your walls for drywall installation, ensuring a flawless result. Why Wall Preparation is Important Before you can hang drywall, it's essential to ensure that your walls are properly prepared. Proper preparation helps: Ensure a Smooth Finish: Prepping the walls prevents imperfections that could affect the final appearance of your drywall. Increase Durability: Addressing underlying issues, such as moisture or structural weaknesses, helps prolong the lifespan of your drywall. Save Time and Money: Proper preparation reduces the likelihood of costly repairs down the line. Step-by-Step Guide to Preparing Your Walls for Drywall Installation 1. Clear the Workspace Before starting any drywall project, it's essential to create a clean, clutter-free workspace. Remove furniture, decorations, and any other items that may obstruct your work area. This will not only make the job easier but also ensure your belongings are protected from dust and debris. Tip: Cover floors with drop cloths or plastic sheeting to prevent damage from dust or falling debris. 2. Inspect the Walls for Damage Take the time to thoroughly inspect your walls for any signs of damage. Look for: Cracks: Small cracks may indicate settling, while larger cracks could suggest structural issues. Moisture Damage: Check for water stains, mold, or mildew, which could indicate leaks or high humidity. Pests: Ensure there are no signs of termite or pest damage. Tip: Address any damage before installing drywall to prevent further issues. 3. Repair Any Wall Damage If you find any damage during your inspection, make the necessary repairs before proceeding. Here's how to address common issues: Cracks and Holes: Fill small cracks and holes with joint compound, then sand smooth. For larger holes, use a patch kit or cut out the damaged section and replace it with new drywall. Moisture Issues: Fix any leaks and use a dehumidifier to dry out damp areas. Consider using mold-resistant drywall in areas prone to moisture. Pest Damage: Consult a pest control professional if needed, and repair any damaged wood or insulation. 4. Check Wall Framing and Insulation Before hanging drywall, it's crucial to ensure that your wall framing is solid and secure. Use a level to check that your studs are plumb (vertically straight) and evenly spaced, typically 16 inches apart on center. If necessary, adjust the framing to create a smooth, even surface for drywall installation. Insulation: If your walls aren't already insulated, this is the perfect time to add insulation to improve energy efficiency and soundproofing. Tip: Consider using foam or fiberglass batt insulation to enhance your home’s thermal performance. 5. Install Electrical and Plumbing If you're planning to add new electrical outlets, light switches, or plumbing fixtures, now is the time to do it. Installing these elements before hanging drywall will save you the hassle of cutting into newly installed walls later. Tip: Work with a licensed electrician or plumber to ensure that your installations meet local building codes. 6. Install Vapor Barrier (If Needed) In colder climates like Saskatoon, installing a vapor barrier is essential to prevent moisture from seeping into your walls and causing damage. A vapor barrier helps protect your insulation and framing from moisture build-up, which can lead to mold and mildew. How to Install: Use plastic sheeting or specialized vapor barrier products, securing them with staples or adhesive. Make sure to overlap seams by at least 6 inches and seal them with tape. 7. Add Backing for Heavy Fixtures If you plan to hang heavy items like shelves, cabinets, or a wall-mounted TV, install additional backing between the studs. This will provide extra support and prevent your drywall from cracking under the weight. Tip: Use 2x6 boards as backing and attach them securely to the studs where needed. 8. Clean the Wall Surface Before installing drywall, make sure your walls are clean and free of dust, debris, or any loose materials. Use a vacuum or a broom to clean the surface thoroughly. Tip: Wipe down the studs with a damp cloth to ensure that dust doesn't interfere with the adhesive properties of the drywall. 9. Mark Stud Locations Once your walls are prepped, use a pencil or chalk line to mark the location of the studs. This will make it easier to secure the drywall sheets during installation. Tip: Use a stud finder for accurate marking, and mark each stud along the floor and ceiling for easy reference. 10. Gather Your Drywall Supplies Before you begin hanging drywall, make sure you have all the necessary tools and materials on hand: Drywall sheets Drywall screws or nails Drywall saw or utility knife Tape measure T-square or straight edge Joint compound and drywall tape Sanding block or drywall sander Why Choose Saskatoon Drywallers for Your Drywall Installation?
