Concrete grinding in Geelong is one of the most sought-after processes that requires the most attention. Many homeowners or commercial property owners in Geelong often choose sealing concrete following grinding the concrete floors to tone down the concrete and extend its life. As much as these processes are essential for effective surface preparation, knowing their costs is important to prepare the budget effectively.
In this blog, we will uncover common and hidden costs of concrete grinding and sealing in Geelong and Melbourne to help you set aside an effective budget.
Understanding Concrete Grinding and Sealing
Concrete grinding in Geelong is a popular and essential surface preparation technique for layering out the top concrete. This practice helps in achieving a smooth concrete that is free of any imperfections.
On the other hand, sealing concrete is the next step after the grinding process. Many homes or commercial spaces in Melbourne consider high-quality concrete sealants for this purpose to protect the concrete against moisture, wear, and staining issues.
Now, let’s understand the average costs and factors that can increase or decrease the costs of grinding or sealing a concrete for your area.
Factors Affecting the Cost of Concrete Grinding and Sealing
It is important to note that the average cost for concrete grinding in Geelong is $10 – $60 or higher, depending on many factors.
Here are a few factors to consider when undertaking the concrete grinding process in Geelong.
Factors Influencing the Cost of Concrete Grinding
1. Impact of Square Footage on Cost:
The size of the area significantly affects the overall cost. Larger areas require more time, materials, and labour which adds up to the total costs. Contractors often provide a per-square-foot rate, however this can be economical if you are aiming for multiple rooms.
It is always wise to consult with contractors performing concrete grinding in Geelong in advance to be clear about the final price.
2. Condition of the Concrete
The condition of the concrete impacts the grinding costs as well. For example, if the concrete has minor cracks or pits or looks uneven, then filling cracks and smoothing the rough structure calls for additional repair costs. This can be an additional repair cost ranging from $1 – $3 per square foot, which is a must-repairing process before commencing grinding.
3. Investment in Specialised Grinding Equipment
In addition to the size of the area and the condition of the concrete, the type of grinding tools used in the process can also influence the cost of concrete grinding.
For example, if a contractor allows the use of a basic grinding tool for the basic grinding process, then the price will be lower. However, if your contractor invests in renting or purchasing the advanced or planetary grinding tools, then you may have to bear additional costs.
4. Intricate Designs Adds Costs:
Projects requiring grinding intricate designs or patterns can increase costs because they involve more labour and clarity on completion. Decorative elements such as inlays or borders add complexity.
Some projects may require multiple grinding steps with different grits, adding to the time and labour involved. Complex designs and multi-step processes can add $1 to $3 per square foot.
Factors Influencing the Cost of Concrete Sealing in Melbourne
1. Type of Sealer Used
Here are all the types of sealers used in concrete sealing that affect the total costs.
● Acrylic Sealers:
These types of sealers are easily available and are generally used for basic protection and adding medium shine. Acrylic sealers are the most affordable option and cost only $0.50 to $1.50 per square foot in Melbourne.
● Epoxy Sealers:
If you are sealing concrete in commercial or industrial spaces with heavy foot traffic, then investing in high gloss and durable epoxy sealers becomes a necessity. Their prices can range from $2 to $4 per square foot.
● Polyurethane Sealers:
These sealers’ costs range from $2 to $4 per square foot for their use in heavy industrial settings, requiring a complete chemical resistance shine on concrete floors.
● Penetrating Sealers:
Designed to protect the concrete from within, these are ideal for outdoor surfaces exposed to harsh conditions. Costs range from $1 to $3 per square foot.
2. Cleaning After Grinding
Thorough cleaning of the surface before sealing is necessary to ensure the sealants apply well to the surface. This process can add $0.50 to $1 per square foot.
Addressing any remaining imperfections after grinding, such as minor cracks or pits, adds to the cost. Minor repairs might add $1 to $2 per square foot, while extensive repairs can add $2 to $5 per square foot.
3. Desired Finish
Concrete sealing in Melbourne requires additional coatings and finishes, which can increase the cost. However, the decision to choose a type of finish is often subjective; for instance, opting matte finish can add about $1 to $2 per square foot, and glossy ones can charge you $2 to $3 per square foot.
Lastly, textured finishes are more expensive than the former two due to their application on custom or decorative surfaces, combining $2 to $5 per square foot.
4. Number of Coats
Applying a single coat of sealer is less expensive and is ideal if you are using high-quality finishes. Multiple coats enhance durability and appearance but increase labour and material costs. Each additional coat can add $0.50 to $1 per square foot.
5. Application Method
Using rollers is less expensive and is suitable for smaller or less demanding areas. On the other hand, spraying sealants for larger areas or even finishing will definitely spike the price.
Additional Costs to Consider:
Here are extra costs that you must consider before hiring a contractor to grind or seal concrete.
● Labour Costs:
Hiring experienced professionals for concrete grinding or concrete sealing in Melbourne ensures high-quality work but comes at a higher cost. Labour costs in Melbourne typically range from $2 to $5 per square foot
● Environmental Conditions
Sealing outdoor concrete might require more durable sealers that can withstand weather conditions, potentially increasing costs than indoor. The local climate can affect the drying and curing time of the sealer, influencing labour costs and the number of coats required.
● Accessibility of the Site
Sites that are difficult to access or require significant preparation to reach (e.g., high-rise buildings, confined spaces) can increase labour costs.
● Timeline and Urgency
If you are allowing concrete grinding or sealing work outside of normal business hours (e.g., nights or weekends), then additional charges may apply for urgency.
● Cost of Removing Existing Flooring or Coatings
Removing old paints, tiles, carpets, or other coatings off the concrete before grinding comes at an additional cost. Likewise, asking for anti-slip additives, decorative dyes or custom patterns in sealants comes at a higher price.
Final Words
Budgeting for concrete grinding in Geelong is essential considering the area size, condition of concrete, using specialised grinding tools and techniques, and the length of time. Similarly, sealing concrete in Melbourne requires looking after cleaning, removing leftover imperfections, and using effective sealants, finishes, and techniques of application to arrive at the final price.
