Painting too soon after drywall installation is one of the most common mistakes homeowners make. Fresh drywall needs time to fully dry, cure, and settle before any primer or paint is applied. Rushing this process can cause bubbling, cracking, or uneven coverage. All Star Walls provides professional drywall installation and finishing for Edmonton homes and offers expert guidance on when it is safe to paint.

Why Timing Matters After Drywall Installation
Proper drying ensures a smooth surface and long-lasting paint adhesion. New drywall goes through several stages, including mudding, sanding, and priming, each of which adds moisture to the surface. Painting before that moisture fully evaporates traps it under the paint layer, leading to visible flaws and premature wear.
In Edmonton’s fluctuating climate, temperature and humidity also play a major role in how long drywall takes to dry. Allowing proper time between each stage protects your investment and ensures a professional-looking result.
Drying Time for Joint Compound (Mudding)
After drywall panels are hung, joints and screw holes are covered with joint compound or “mud.” Each coat of mud must dry completely before the next layer is applied.
- Typical drying time: 24 to 48 hours per coat
- Influencing factors: room temperature, airflow, and humidity levels
- Dryness test: compound should be hard, chalky, and evenly colored before sanding
In cooler or more humid environments, drying may take longer. Increasing airflow with fans or slightly raising the room temperature helps speed up the process without compromising quality.
Priming Before Painting Drywall
Once all sanding and cleaning are complete, the next step is applying primer. Primer seals the drywall surface, evens out porosity, and helps the topcoat adhere properly.
Allow primer to dry for at least 24 hours before painting, though Edmonton’s dry indoor conditions may shorten that slightly. For new drywall, a PVA (polyvinyl acetate) primer works best because it binds directly to the drywall paper and joint compound. Always check the manufacturer’s label for specific drying times.
Environmental and Seasonal Factors in Edmonton
Edmonton’s climate significantly affects drywall curing times. During winter, indoor heating creates dry air, which can cause mud to dry too quickly on the surface while staying damp underneath. In summer, higher humidity can slow down drying and lead to longer wait times.
To maintain ideal conditions:
- Keep room temperature between 15°C and 25°C
- Maintain humidity around 40% to 50%
- Use fans or dehumidifiers for ventilation
- Avoid painting during extreme cold snaps or humid days
Controlling the environment helps the compound cure evenly, preventing future paint adhesion problems.
Risks of Painting Too Soon
Painting before drywall has properly dried can create multiple issues, including:
- Bubbling or peeling: trapped moisture pushes paint off the surface
- Uneven color or texture: wet mud can bleed through primer
- Cracking or blistering: excess moisture expands under paint layers
These issues not only affect appearance but may require complete repainting later. Waiting the recommended time between each step ensures your walls look clean, smooth, and professional for years to come.
Best Practices for a Flawless Finish
Follow these steps for an even, durable result:
- Let each coat of mud dry for 24–48 hours
- Sand and clean surfaces thoroughly before priming
- Apply a quality PVA primer and let it dry fully
- Wait at least 24 hours before painting
- Use balanced temperature and humidity during the entire process
For homeowners seeking a perfect finish, professional drywall installation in Edmonton ensures every stage meets local conditions and material standards.
