When homeowners choose low-cost plastering options, the finish may look perfect at first. Within a few months, things start falling apart. This is a common issue which experienced plastering companies in Melbourne come across while working on plaster repairs.
What usually happens when you choose cheap work:
- Visible cracks within 3 to 6 months.
- Lines are seen after painting.
- Ceiling movement and cornice gaps.
- Early shrinkage and defects on the surface.
Vista Plastering has over 35+ years of experience with plastering in Melbourne. Our Melbourne plasterers have fixed hundreds of installations that failed because of rushed workmanship. This blog will discuss the hidden cost of cheap plastering and how working with professionals will prevent failure.
Cheap plastering often cracks within six months because of rushed jointing, poor plasterboard installation, building movement and use of low-quality materials. In Melbourne, timber shrinks and expands with the seasonal changes, which puts more stress on weak joints. Professional plasterers prevent this by using the right fixing, reinforcement, drying time, and movement allowances.
Why Do Cheap Plastering Jobs Crack Within Months?
Most early cracks show up at plasterboard joints. Cheap installations often skip the time it takes to layer and dry.
Some of the common shortcuts include:
- Thin coats of joint compound.
- No tape for reinforcement.
- Sanding too quickly.
- Painting before drying.
Joints can’t handle normal building movement without reinforcement. After building, many homeowners look for “plasterers near me” to get local support. Proper jointing makes sheets stronger and ensures they don’t come apart.
Common site errors that can shorten the life of a project. Working with the right plastering team can help you avoid these common plastering mistakes.

How Does Poor Plasterboard Installation Lead to Cracking?
Incorrect plasterboard installation is one of the biggest causes of early failure.
Cheap work usually means the following:
- Incorrect spacing of screws.
- Fixing the loose board.
- No back-blocking.
- Boards not aligned to framing.
When boards flex, stress shifts to the joints. This causes cracks to appear along seams. Professional gyprock plasterers implement Australian standards for screw spacing and reinforcement, which reduces movement.
Ceilings are especially vulnerable. The stress on a poorly installed roof increases due to a rise in heat and roof movement.
Does Building Movement Affect Plastering in Melbourne Homes?
Movement is normal, especially in Australian houses with timber frames. Proper Melbourne plastering accounts for the following:
- Shrinkage of the timber frame.
- Settlement of the slab.
- Seasonal soil movement.
- Changes in temperature.
Cheap labour work does focus on movement fixes. Control joints and expansion gaps are skipped. Cracks form quickly when the building settles.
This is why even small problems can get worse. Small damage can quickly turn into major plaster repairs.
Why Do Low-quality Materials Increase Cracking Risk?
Cheap compounds shrink more during drying. They also have weaker bonding strength.
Problems caused by low-grade materials:
- The joint is sinking.
- Cracks in the hairline
- Weak adhesion.
- Bubbles on the surface.
Experienced plasterers use premium compounds designed to minimise shrinkage. These materials include fibres for strength and better bonding.
The durability of the work also depends on the quality of the materials used. Many homeowners underestimate the lifespan of plastering, and working with professionals will help you get the most of it.
What Role Does Drying Time Play in Plaster Cracking?
One of the most common problems is rushed drying. Cheap plastering jobs in Melbourne often put on multiple coats too quickly.
This ensures:
- Excess shrinkage.
- Weak bonding.
- Lines where the joints are visible
- Cracks appearing after cracks.
Before you put on the next coat, each one must dry. Professional plasterers allow the plaster to dry naturally to avoid stress from shrinkage.
Why Do Ceiling Cracks Appear More Often?
Ceilings move more than walls do. Cheap ceiling work often lacks the following:
- Proper screw spacing.
- Back-blocking.
- Proper support for joints.
When heat gets into the roof cavities, movement increases. Weak joints break easily. This is why ceiling cracks are often the first things visible when a Melbourne plastering company didn’t do a proper job.
Avoid Cheap Work From Costing You More Later
The Real Cost of Cheap Plastering
Cheap work saves money upfront but leads to:
- Repainting
- Joint repairs
- Section replacement
- Full re-plastering
The cost of repairs is often more than the original savings. This is why people often call on experienced plasterers to do corrective work.

Cheap plastering may look smooth at first, but cracks will appear in a few months due to poor jointing, improper plasterboard installation, and rushed drying.

FAQs
How long should quality plastering last?
If done right, plastering should last for a long time without cracking. Natural movement of the building can cause small hairline cracks to form, but major joint separation within six months usually means that the plasterboard was not installed properly, dried too quickly, or was not solidified enough.
Are cracks in new homes normal?
Settlement can cause small cracks in the hairline. But large cracks in joints, ceilings, or corners are not normal. To control movement and stop early failure, professional plasterers place control joints and reinforcement.
Can cheap plastering be repaired?
Yes, but repairing often means taking off joint compound, re-taping, and re-finishing. In severe cases, boards have to be reinstalled. A qualified plastering company in Melbourne can tell you if it’s better to fix or if replacing is the right thing to do.
Do better materials really make a difference?
Yes. Premium compounds shrink less and stick together better. Experienced plasterers use high-quality materials to lower the risk of cracks and make the plaster last longer, especially in Melbourne’s changing weather.
