Understanding Cumaru Deck Tile Dimensions and Area Coverage
Lumber Plus offers Cumaru deck tiles in two primary sizes: 12 x 12 inches and 24 x 24 inches. While both are square formats, their area coverage differs significantly, impacting how many tiles are needed for a given space.
A 12 x 12 inch Cumaru deck tile covers 1 square foot. This compact size is often chosen for smaller areas or layouts that incorporate numerous edges, curves, or transitions, as it offers greater flexibility in fitting irregular spaces.
A 24 x 24 inch Cumaru deck tile covers 4 square feet. This larger format is well-suited for more expansive terraces and open surfaces where a clean, less segmented appearance is desired due to fewer tile seams.
Designing with 12 x 12 Cumaru Deck Tiles
The 12 x 12 inch Cumaru deck tile provides design flexibility, particularly for intricate layouts or smaller, irregularly shaped areas. Its smaller module size allows for more precise cuts around obstacles like columns, planters, or unique architectural features. This can be advantageous when creating patterns or defining distinct zones within a larger space.
For projects like apartment balconies, pathways, or areas with frequent changes in direction, the 12 x 12 tile can minimize waste from complex cuts, provided the layout is carefully planned. The increased number of seams can also add a textural element to the overall design.
Designing with 24 x 24 Cumaru Deck Tiles
The 24 x 24 inch Cumaru deck tile is ideal for projects that prioritize a broad, uninterrupted surface. Its larger size reduces the number of seams, creating a more expansive and contemporary aesthetic, often preferred for rooftop terraces, large patios, or open-plan outdoor living areas.
While the larger tile can simplify installation over large, unobstructed areas, it requires careful consideration for edges and cuts. Any cuts made to a 24 x 24 tile result in a larger offcut, which may be less reusable than offcuts from a 12 x 12 tile if not planned strategically. This size is generally more efficient for rectangular or square spaces with minimal obstructions.
Worked Example: Calculating Tiles for a 10-foot by 8-foot Terrace
Let's consider a hypothetical rectangular terrace measuring 10 feet (120 inches) by 8 feet (96 inches). The total area is 80 square feet. We will calculate the tile quantity for both 12 x 12 and 24 x 24 Cumaru deck tiles, accounting for edge cuts.
For 12 x 12 inch tiles (1 sq ft per tile):
Along the 10-foot (120-inch) side, you would need 120 inches / 12 inches/tile = 10 tiles.
Along the 8-foot (96-inch) side, you would need 96 inches / 12 inches/tile = 8 tiles.
Total tiles for a perfect fit: 10 tiles x 8 tiles = 80 tiles. In this specific scenario, with dimensions perfectly divisible by 12 inches, no cuts are strictly necessary, and the area-equivalent coverage matches the purchase quantity.
For 24 x 24 inch tiles (4 sq ft per tile):
Along the 10-foot (120-inch) side, you would need 120 inches / 24 inches/tile = 5 tiles.
Along the 8-foot (96-inch) side, you would need 96 inches / 24 inches/tile = 4 tiles.
Total tiles for a perfect fit: 5 tiles x 4 tiles = 20 tiles. Again, in this specific scenario, with dimensions perfectly divisible by 24 inches, no cuts are strictly necessary, and the area-equivalent coverage matches the purchase quantity.
Now, consider a slightly different scenario: a terrace measuring 11 feet (132 inches) by 9 feet (108 inches). Total area is 99 square feet.
For 12 x 12 inch tiles:
Along the 11-foot (132-inch) side: 132 inches / 12 inches/tile = 11 tiles.
Along the 9-foot (108-inch) side: 108 inches / 12 inches/tile = 9 tiles.
Total tiles: 11 tiles x 9 tiles = 99 tiles. Still a perfect fit, no cuts.
For 24 x 24 inch tiles:
Along the 11-foot (132-inch) side: 132 inches / 24 inches/tile = 5.5 tiles. This means you need 6 full tiles to cover this length, with the last tile cut to 12 inches.
Along the 9-foot (108-inch) side: 108 inches / 24 inches/tile = 4.5 tiles. This means you need 5 full tiles to cover this length, with the last tile cut to 12 inches.
Total purchased tiles: 6 tiles (for length) x 5 tiles (for width) = 30 tiles. This is more than the 99 square feet / 4 square feet per tile = 24.75 tiles (approximately 25 tiles) area-equivalent coverage. The extra tiles account for the necessary cuts, and some offcuts might be reusable if their dimensions match other required partial tiles.
This example illustrates that while 12x12 tiles might seem to generate more cuts in general, in specific dimensions, 24x24 tiles can lead to more significant offcuts if the project dimensions are not perfect multiples of 24 inches. Always consider the actual dimensions and how the tiles will lay out along each edge.
Planning for Cuts and Waste
Regardless of tile size, some degree of cutting will likely be necessary, especially for non-rectangular areas, around columns, or when creating custom borders. It is generally advisable to order an additional 5-10% of tiles beyond your calculated quantity to account for cuts, potential mistakes, or future replacements. The exact percentage depends on the complexity of your layout.
With 12 x 12 inch tiles, smaller offcuts might be more easily repurposed for other small sections or repairs. With 24 x 24 inch tiles, careful planning is crucial to maximize the use of larger offcuts, especially if multiple partial tiles of the same size are needed.
Consider the tools required for cutting. Cumaru is a dense tropical hardwood, so appropriate cutting blades and safety equipment are essential for clean and accurate cuts.
Installation Considerations
Both 12 x 12 and 24 x 24 Cumaru deck tiles can be installed over various stable, level surfaces, including concrete patios or existing decks. They can also be used with pedestal systems, which allow for leveling over uneven surfaces and provide access to the sub-surface for drainage or utilities. Ensure that any chosen pedestal system is compatible with the specific dimensions and weight of the Cumaru deck tiles.
Conversely, the smaller 12 x 12 tiles may offer more flexibility in navigating complex perimeters or curves.
Always review the manufacturer's installation guidelines for the specific Cumaru deck tile products you select to ensure proper assembly and long-term performance.
Before you order
- Project Area Dimensions: Measure the length and width of your outdoor space accurately in inches.
- Layout Complexity: Are there many curves, columns, or irregular shapes to work around?
- Aesthetic Preference: Do you prefer a more segmented look with more seams (12x12) or an expansive, cleaner surface (24x24)?
- Cutting Plan: Sketch out your layout to identify where cuts will be needed and estimate offcut sizes.
- Waste Factor: Account for 5-10% extra tiles for cuts and potential errors.
- Installation Method: Are you laying directly on a surface or using a pedestal system? Confirm tile compatibility.
- Budget: While area coverage differs, the total cost will depend on the unit price per tile and the waste generated.
Confirm installation details, approved uses and warranty terms in the current instructions for the exact product and profile. Your installer should verify the substrate, structure and applicable project requirements.
Questions to help you decide
What are Cumaru deck tiles made of?
Cumaru deck tiles are crafted from Cumaru, a tropical hardwood. It is recognized for its rich reddish-brown color and natural strength, making it a durable choice for outdoor decking.
Can I mix 12 x 12 and 24 x 24 Cumaru deck tiles?
While technically possible, mixing tile sizes typically requires careful planning to ensure a cohesive and structurally sound layout. The different dimensions mean that alignment and support systems would need to be precisely managed. Most designs benefit from using a single tile size for a uniform appearance and simpler installation.
How do I clean and maintain Cumaru deck tiles?
Cumaru deck tiles generally require routine cleaning with mild soap and water to remove dirt and debris. Like all natural hardwoods, Cumaru will gradually silver or gray over time if left untreated. To maintain its original reddish-brown color, periodic application of a suitable deck oil or sealant is recommended. Always follow the specific maintenance guidelines provided by the product manufacturer.
