With this idea book, we would like to give you a guide that explains step by step how to make DIY stucco and attach it to walls and ceilings.


Before you start your project for DIY stucco, you should be aware of the later picture of your stucco decorations. Take the time to measure the walls and ceilings, sit down with pen and paper at the desk and determine where to put the stucco moldings, rosettes or brackets.

Possibility Number 1 - Beautiful stucco elements can be bought in many hardware stores. These components are usually made of polystyrene. For assembly in DIY you need the following tools: stucco rosette, stucco molding and possibly stucco console, miter saw, miter box, universal glue, acrylic varnish and brush.

Option 2 - In DIY stores you can also buy gypsum-molded stucco, which corresponds to a traditional construction method. The material plaster makes the assembly of the DIY stucco a time-consuming project that you need this working tool: stucco elements of your choice, plaster adhesive, mixing vessel, small spatula, bucket of water, sponge, brush, sandpaper, nails, hammer, possibly screws and Screwdriver.

Rosettes, consoles and moldings are the three forms in which the stucco element can show itself. With moldings, surfaces are edged or bounded, while stucco rosettes usually form the center of a ceiling. Consoles are stucco elements that are particularly reminiscent of the Baroque architecture and are mounted on this model on walls. Real stucco, which you find on the ceilings and walls of old-style apartments, is traditionally made of plaster. However, the most modern variant for the stucco types mentioned is styrofoam - and not without reason, as you will learn in the next section to DIY stucco.

Plaster or styrofoam?

For your DIY stucco project with plaster and styrofoam you have two materials available that present themselves as ledges, rosettes and consoles in similar decorative forms, but their features could not be more different. The choice of gypsum or polystyrene is not only a matter of taste, but is even more dependent on the load of your walls and ceilings. This could already be a first decision to one or the other base material for your DIY stucco fall. 

In contrast to gypsum, Styrofoam is an extremely lightweight material that can be easily carried by all room surfaces. In addition, this plastic is inexpensive and easy to install. Especially after the attached Styrofoam is painted, a difference to the natural material plaster can hardly be recognized. But disadvantages are also attributable to the polystyrene ornaments: the material is flammable and can quickly deform when exposed to heat. A fire seal guarantees you the purchase of such components security. 

The natural product gypsum is absolutely fireproof and has a regulating effect on the indoor climate. While styrofoam components are often dedicated to more modern ornaments, gypsum can be used to faithfully reproduce original designs by using old molds. However, mounting this DIY piece may be difficult when thin elements such as stucco moldings begin to break.

Design profiles and shapes

Creating DIY stucco single-handedly is actually a breeze: A rubber bowl is mixed to 1/4 with water and carefully with model plaster. Steady stirring with a metal spatula results in a lump-free mass whose strength is optimal when no more water can be absorbed. Now it is very important to continue working on the plaster. Carefully brush your plastic molds with the plaster and then fill in the plaster. With a spatula, you smooth the mass accurately and let the plaster rest and become firm. After about 24 hours you can carefully plunge your DIY stucco and attach according to our instructions at the desired location.

Styrofoam or plaster moldings are cut to the desired size using a miter box and stonework saw. Rosettes, which are used as lamp rosettes, must be added by drilling a cable opening.

Prepare the ceiling

Before your DIY stucco can show up in your room, you need to have the structural integrity of the ceiling checked by a structural engineer. Bless this from your plan, it can finally start with the attachment. First you grab a pencil and transfer the position for your strips, rosettes & Co. on the ceiling. To keep your DIY stucco securely on the ground, it must be cleaned meticulously. Removes old plaster, paint and wallpaper remnants or uses plasterboard as the ideal carrier material. A flat surface also promises a secure hold for DIY stucco. You can determine any bumps with a chalk line, which is set there, where stucco moldings and rosettes should later find their place. Then you balance uneven areas by applying or removing mass first, until the chalk line marks this area as level. Before you can apply the DIY stucco, you roughen his later position on the ceiling with a spatula and wet it about 15 minutes before you begin the gluing process.

Attach stucco

Keep in mind that you need DIY Stucco Styrofoam Universal Glue and DIY Stucco Plaster Gypsum Glue. The latter is mixed with water until the firmness resembles quark, and this is immediately distributed on the stucco elements. With slight jerking movements, you press the shapes on your markers and try to align them accurately. It is guaranteed to emerge adhesive on all sides, but you simply wipe with sponge or spatula. One hour can pass until the adhesive cures. Until then, particularly heavy plaster components are temporarily held in place with nails and, if necessary, screwed tight. After one hour, the glue is hard, so the fine sanding can be done. Unclean transitions between the DIY stucco and the ceiling are grouted in the last step by filling filler with fillers on gaps is gekleistert. With fine-grained sandpaper, the supernatants are carefully sanded off. Creating stucco in DIY is a challenge, if not a masterpiece, that will be worthwhile in spite of all the effort. Those who want to give their living space a new aura with a DIY project should also take a look at this book of ideas.
