DIY concrete flowerpots: formwork shapes and pouring technology

A fun and creative do-it-yourself project that gives your garden or home decor a personalized touch is making your own concrete flowerpots. You can create stunning and long-lasting pots with the correct supplies and a little advice. For novices and experienced do-it-yourselfers who want to learn more about the versatile world of concrete, this project is ideal.

To begin creating concrete flowerpots, one must first recognize the significance of formwork shapes. The frames that give your concrete its shape are called formwork or molds. These can be as basic as straight-sided boxes or as complex as decorative patterns. If you want something more personalized, you can make your own molds out of silicone, cardboard, and plastic containers instead of buying pre-made ones. Take your time when choosing or designing a shape that meets your aesthetic vision, as the formwork you choose will have a significant impact on how your pots turn out in the end.

It’s time to mix and pour the concrete after your formwork has been ready. To get a smooth, workable consistency, the proper amounts of cement, sand, and water are combined during the mixing process. A thorough mixing is necessary to prevent lumps and dry areas. Concrete must be poured into the molds carefully and patiently. Gently tap the mold’s sides to eliminate any air bubbles and guarantee a consistent, sturdy structure after the concrete hardens.

The concrete requires time to cure after pouring. Curing is an important process that gives concrete its strength and hardness. Several days may pass during this process, based on the size and thickness of your flowerpots. To stop the concrete from cracking during this time, it’s critical to keep it moist. After the formwork is completely cured, you can enjoy your brand-new, hand-made flowerpots. You can turn a straightforward do-it-yourself project into a distinctive addition to your living area with a little imagination and work.

Concrete flowerbed: what"s so great about it?

The most prevalent component of public landscape design is concrete flowerbeds. And the reason for their popularity isn’t just their affordability and usefulness—there are other benefits to concrete as well.

Positive characteristics

There are plenty of materials, even contemporary ones, that can be used to create a street flowerbed. Glass, plastic, or metal can be used to create flowers.

You can use pricey, yet ecologically friendly materials like wood. The allure of concrete, however, lies in its ability to mimic any surface because it is an entirely unique material.

Concrete can be treated in a specific way to make flower beds made of wood or metal. The product will be highly affordable and ecologically friendly at the same time.

Among this material’s other appealing qualities are:

• Resistance of concrete structures to temperature changes.
• Concrete products, if properly treated, have a very significant service life.
• Due to their significant weight, concrete flower beds can be used for zoning space and as a protective barrier.
• The ability to install and mount concrete flower beds vertically can allow you to green the yard area while preserving space.

A little about the disadvantages

Although there aren’t many drawbacks to concrete flower beds, they should be considered when creating and arranging one.

• In order for concrete to serve for a long time in outdoor conditions, frost-resistant additives must be added to the solution, which will increase the cost of the product.
• The appearance of the surface of untreated concrete is not very attractive, so the flowerbed will require decorative treatment.
• The significant weight of the flowerpot limits its movement, so it is better to immediately determine the place for its installation.
• A concrete flowerbed, even a small one, looks quite impressive, so it may not always fit into the proposed space.

Making your own concrete flowerpots at home is an easy, fun project that blends imagination and usefulness. This guide will help you choose the formwork shapes that work best for your space and style, from straightforward plastic containers to more complex molds. Additionally, you will discover the critical procedures for blending and pouring concrete to create long-lasting and eye-catching pots. You can create one-of-a-kind flowerpots that complement your home or garden’s aesthetic and give your plant displays a personal touch with a few simple tools and supplies.

Sizes and installation locations

Concrete flowerpots can be made at home in practically any size or shape. Here, your only constraints are physical space and your creativity.

The flowerbed’s weight and degree of mobility are determined by its size. Concrete flowerbeds for decoration can be moved or left stationary.

In addition to being decorative, the stationary concrete flowerbeds in front of the display case also serve as a deterrent to vandalism.

Installation levels

Concrete flower beds can be positioned either vertically or horizontally, and at varying elevations above the ground.

There are differences between the following kinds of flower beds:

• Floor. No restrictions on the installation location. As a rule, they have a significant mass and are stationary. Such flower beds are often used to limit access areas or fence off parking lots.

• Pedestal. This type of vases is lighter and is installed above ground level. Sometimes mounted on railings or stairs. During installation, for safety reasons, additional fastening mechanisms are always used.

• Vertical. Such concrete vases have the least weight. Attached to the surface of walls or fences. They are often used to create green barriers.

Although it won’t take up much room, a tiny vertical flower bed can be a great accent piece for a vacant yard corner.

Forms

Since concrete mortar is a liquid plastic, practically any shape can be achieved for a concrete flower garden. The challenge is in forming the formwork with the necessary contours. However, contemporary building materials like fiberglass and ABS (acrylonitrile, butadiene, styrene) plastic come to the rescue in this situation.

Since the creation of these forms necessitates specific financial outlays, formwork for repeated use is created with their assistance. However, using such forms to produce concrete flowerpots allows for the creation of more intriguing flowerbed arrangements.

Fiberglass

Kind of material used in composites. The technology used in manufacturing is straightforward:

• Take a ready-made, liked flowerbed and glue it with fiberglass.
• As a binder, a composition based on epoxy resin is usually used. It fills the space between the fibers of the fabric, and, hardening, retains the shape of a given object.
• To obtain a working form from fiberglass, you need to glue the flowerpot you like on all sides. After the material dries, the form is cut off. Usually several cuts are made in order to carefully remove the sheets.
• After removal, it is necessary to determine how it will be more convenient to fill the formwork and form the parts. For this, the cut pieces are glued together with the same fiberglass.
• Such forms have a long service life, are unpretentious in storage. They can be used to make any, relatively small items.

ABS plastic

Contemporary synthetic polymer with a yellowish hue. Acrylonitrile, butadiene, and styrene—the constituent monomers that make up its composition—are the sources of its name.

These monomers combine with thermoplastic resin to form a stable polymer. Owing to its technical properties, it has been widely used as a structural and engineering material.

Completed forms have a lengthy service life and are very robust. The qualities are similar to those of fiberglass, but less expensive. It is possible to create a mold with a lot of tiny pieces using ABS plastic.

Speaking of which, You can make these forms yourself, or you can buy them ready to pour. Although there isn’t much of a price difference, ABS plastic has a marginally longer service life.

Preparing the mold or installing the formwork

The only difference in producing concrete flowerpots through the use of formwork or pouring into a completed form is the kind of structure that will eventually house the flower garden. The finished form’s walls should be treated with a water-repellent substance before construction begins.

The purpose of doing this is to keep the concrete structure strong. Furthermore, this will make it simple for you to take the concrete product out of the mold.

DIY formwork

A concrete flower bed form is something you can create with your hands. Basically, you have to put together formwork that is the specified size and shape. Simple formwork is typically created separately using thick cardboard or different-sized plastic bottles.

When contemplating crafting concrete flowerpots by hand, consider the following subtleties:

• In the lower part of the formwork, you should install objects that will later form holes for the drainage of excess water from the flowerbed.
• Ordinary plastic bottle caps can be used as such objects. After the solution has hardened and the formwork has been removed, they should be removed
• When assembling the outer and inner parts of the formwork and fixing them relative to each other, keep in mind that the thickness of the concrete wall should not be less than 30 mm. Otherwise, there is a high probability that the flowerpot will quickly crack.

Note: An external formwork can be made out of a hole in the ground if you need to make a large flowerpot. To prevent water loss from the concrete, the hole needs to be covered with polyethylene film before the solution is poured.

Production technology

How can you create a concrete flowerpot by hand? We’ve thought about the possible forms for forming. We will now instruct you on how to mix and pour the mixture.

The procedure is very easy to follow:

• After the form is selected or the formwork is assembled, the internal walls should be treated with a water-repellent substance or lined with polyethylene film.
• Then you should install the parts that will form holes to remove excess water from the flowerpot.
• Next, the concrete solution is mixed and poured. You should pour carefully, avoiding the formation of air bubbles.
• After pouring, the form should be tapped to expel possible air.
• The places where the concrete solution comes into contact with air (usually the top of the formwork) should be covered with polyethylene.
• After filling the form with mortar, leave the future concrete flower bed at rest. The first setting will occur within a couple of days, but the formwork or form should be removed no earlier than after 7-10 days.
• At this stage, the concrete walls will still be relatively “soft”. This will smooth out some rough edges or round the edges.

In this article’s video, you can discover more about the manufacturing process used to create formwork for a concrete flower bed.

Solution

One part cement to three parts sand is the ratio used to prepare the traditional base mortar for pouring. In this instance, it is best to use fine-grained materials that have been sifted free of dirt particles.

During the dry component mixing step, powdered coloring pigment or marble chips of different fractions can be added to the concrete composition to add color and texture. Add marble paint right before pouring into the form, but after the mortar has already been mixed, to achieve a marble effect.

Crucial! Plan ahead for the location and usage of the concrete flower bed. Different additives must be used in the concrete composition depending on the operating conditions. The manufacturer’s instructions for using the additive are printed on the packaging.

Decorating a concrete flowerpot

In the event that you skipped the pouring stage and didn’t use any additives, the flowerpot will need to be adjusted. First of all, to improve its aesthetic appeal. Additionally, to shield the concrete from the effects of moisture in the air. Below are some photos and examples of how to decorate a concrete flower bed.

Mosaic solution

You can use seashells, pebbles, colored bottle glass, broken dishes, and leftover tiles as materials for a mosaic. The pieces are joined to the concrete surface with the proper construction adhesive that dries quickly.

• Before applying the mosaic to the flowerpot, draw a sketch on paper. This will simplify the task and speed up the process.
• If the pattern is complex, draw its outlines on the vase with chalk.
• First, the border elements of the pattern are glued, then the rest of the area is filled.
• Upon completion, it is better to cover the mosaic pattern with varnish suitable for outdoor use on stone

Paint

Painting a concrete vase is the simplest method of product decoration. You can paint a pattern or an ornament on the flowerpot, or you can paint it all one color. Paints intended for use on stone or concrete facades are chosen for the task. The fact that this decorating technique is flexible makes it even more amazing.

Relief patterns

Usually, pre-made forms are used to give the outside of the flowerpot an intriguing texture. Such formwork is used to create flowerpots that resemble trees or flowerbeds with intricate bas-reliefs. Largely venous leaves can be used to create a basic bas-relief by attaching them to the inside of the formwork’s outer edge.

Be advised that patterns in relief go very nicely with paintings.

Creating your own concrete flowerpots can be a fun and creative project that gives your landscaping or interior design a unique touch. You can experiment with different designs to fit your style because there are many different formwork shapes available. Whether your style is more for intricate, detailed designs or simple, minimalist pots, formwork can help you realize your vision.

There are a few essential steps in making these flowerpots: getting your formwork ready, mixing the concrete, and pouring it properly. It’s critical to carefully follow each step to guarantee the durability and strength of your flowerpots. The final result can be greatly altered by using high-quality materials and taking your time when pouring.

Don’t forget to give the concrete enough time to cure so that it sets correctly. If this process is rushed, the structure may become weaker and crack. After your flowerpots have completely dried, you can take off the formwork and feel proud of yourself for having made something useful and one-of-a-kind by hand.

All things considered, making your own concrete flowerpots is not only a great way to express your creativity but it’s also very practical. Your living space will be enhanced by long-lasting, exquisite pieces that you can make by learning the fundamentals of formwork shapes and pouring techniques. Try it out, and you might discover your new favorite pastime.
