12mm vs 18mm Shuttering Plywood - Know The Difference
Shuttering is a process of creating molds for setting up architectural structures like walls, ceilings, pillars, columns, and other customized structural shapes. And shuttering plywood is a special type of plywood designed for the shuttering process.
It's made from multiple (around 9) layers of plywood bonded together with waterproof glue and is available in a variety of sizes and thicknesses. 12mm thickness plywood is commonly used in construction but when you'll go for buying the shuttering plywood, you'll also come across plywood of 18mm thickness or even more!
So, which one to choose from?
This article explains how 18mm or thicker plywood is any different from the thinner ones along with other important details to help you choose the best plywood for your next construction project.
How 18mm plywood is different from 12mm or other plywood?
The thickness of shuttering plywood is achieved by adding more layers of veneers on top of each other. So technically or in terms of construction, 18mm plywood is no different from 12mm shuttering plywood.
The difference lies when it comes to offering repetitions. An 18mm plywood will give more repetitions than the thinner counterpart.
So, what is meant by the term repetition? Repetition of shuttering plywood means the number of times a plywood can be used for fastening without getting swelled or cracked due to water or moisture absorption. Denser plywood offers more repetitions and the thicker the plywood, the higher its density.
In general, a standard 12mm shuttering ply with an (8 x 4) ft size can allow 7 repetitions on one face totaling 14 repetitions with one ply. And the same size of plywood with an 18mm thickness is good for 20 repetitions per face!
Also, 2 plywood with the same thickness may vary in their densities as the density depends upon the number of layers/sheets compressed within the same thickness. But the rule of repetitions will still go the same i.e. denser the shuttering plywood, the more the number of repetitions it can offer.
So, which one to choose from? Well. It depends upon the requirement. Generally speaking, the thicker or denser ply is best suitable for heavy and lengthy construction projects while the 12mm works otherwise.
Some Other Factors Affecting the Repetition
Apart from the thickness, there're several more factors affecting the number of repetitions with shuttering plywood.
The thickness of the Coating
The repetition also depends upon the thickness of the coating done on the sides of the plywood surface. 45GSM is the standard coating thickness done on any shuttering panel but higher quality panels with 60GSM up to 120GSM are also available in the market.
Usage Factor
The way shuttering plywood is used also matters when it comes to its repetitions.
Shuttering plywood if coated with oil will not only offer more repetitions but will also give a good finish and better resistance against moisture and chemicals. The oil mainly protects the coating mantled on the panels.
Likewise, any cut or wear found on the shuttering plywood must be sealed with acrylic paint to prevent water from entering inside the plywood.
What's the price of 18mm shuttering plywood?
The price of 18mm shuttering is slightly higher than the 12 mm thickness shuttering plywood. The price of 12mm thickness plywood ranges from Rs (30-45) per square foot whereas the price of 18mm thickness plywood ranges from Rs(50-70) per square foot. The price also depends on the quality and thickness of the coating done on the panel.

Lightweight
It's lightweight but strong enough to support the weight of the concrete mixture. This makes it easy to transport and handle, even in large projects.
It can be used with metal clamps for forming complex shapes and it also has a smooth surface that is ideal for creating a better finish on the concrete structure.
Durable
It's resistant to water, moisture, chemicals, and other building materials. It can also be used repeatedly since it is relatively easy to clean and maintain than wooden lumbers.
Cost-Effective
Shuttering plywood also becomes cost-effective as it can be used repeatedly during construction. And it's also easy to transport and use which further reduces the overall cost of the project.
Installation and Handling Tips for Shuttering Plywood
The installation and handling of shuttering plywood is important to ensure its durability and also the success of the construction work. Some tips and tricks to achieve the same are:
Before installation, it's important to check the condition of the panels to ensure that they are not too thin or weak.
During installation, it's critical to ensure that the panels are sealed properly and that all the edges are properly aligned.
After installation, make sure that the shuttering plywood is properly secured using the appropriate screws and adhesives.
When handling shuttering plywood, it is best to wear protective gloves, safety glasses, and a dust mask. It is also essential to keep the panels dry and clean to prevent any damage during transport and storage.
When storing, it's important to store shuttering plywood in a dry and well-ventilated area to avoid any damage due to water or moisture.

How Helpful is Shuttering Plywood? - 4 Applications
Shuttering plywood is one of the most common building materials seen at a construction site. It's used to create a mould where cement mixture is poured. It is then allowed to solidify thereby giving the architectural shape as that of the mould.
Due to the effectiveness and affordability of shuttering plywood, it has found its applications in building a wide variety of structures. Structures like walls, ceilings, bridge columns, dams, etc, and across different industries like automotive, furniture, interiors, etc use shuttering plywood.
This article explores in detail the different uses of shuttering plywood along with some top plywood brands in India to go with when it comes to buying shuttering plywood for your construction work.
What is Shuttering Plywood?
Shuttering is a common construction method where a temporary mould of the desired structural shape is first created to pour a cement mixture into the mould. The cement mixture is then allowed to solidify thereby giving a rigid concrete structure. This temporary mould can be made of steel, glass fibre-reinforced plastics, and other materials like wood or plywood.
Shuttering plywood is plywood especially meant for the shuttering process to carry out. It is made the same way as any other plywood or wooden panel, with thin multiple veneers laid on top of each other and glued together with waterproof glue.
Shuttering plywood can help reduce the risk of cracking and warping of the concrete structure during the curing process. It helps by providing a stable and secure surface for pouring and curing the wet concrete. It is also resistant to water and moisture, making it ideal for use in wet environments.
Additionally, shuttering plywood is lightweight and durable and is easy to install and remove. This saves time and labour costs, in comparison to traditional wooden planks used for the shuttering process.
