How to glue terracotta?
A broken pot, a cracked vase, a statuette or a terracotta decoration to repair? To glue terracotta, you must above all choose a glue capable of remaining on this porous surface while allowing precise assembly.
For routine repairs, two solutions are particularly interesting: DENSE cyano glue, whose thick texture facilitates precise application, and the cyano GEL glue, particularly suitable for porous, irregular or vertical surfaces.
The product range superglue colle21 also includes different viscosities allowing the glue to be adapted to the type of break and the object to be repaired.
What glue should I use to glue terracotta?
For a clean break where the pieces fit together correctly, a thick cyanoacrylate glue or gel is particularly practical.
Terracotta is a porous material. Very liquid glue can quickly penetrate its surface. On the contrary, a thicker formulation allows you to better control the application and maintain more product at the joint.
DENSE cyano glue: for precise repair
The DENSE cyano glue is particularly interesting when the two broken pieces fit together correctly.
Its high viscosity allows the glue to be deposited precisely on the edges and to limit dripping.
It can be used in particular to repair:
- a terracotta pot;
- a vase;
- a statuette;
- a decorative object;
- a broken pottery;
- a small ceramic piece.
For a clear break requiring very localized application, the DENSE cyano glue allows you to work cleanly without using an excessive quantity of product.
Cyano GEL glue: ideal for porous terracotta
When the terracotta is particularly absorbent or the break presents irregularities, the cyano GEL glue is an excellent alternative.
Its consistency allows the glue to stay in place and also facilitates repairs on vertical surfaces.
The FREEZE can therefore be particularly practical for:
- flower pots;
- raw terracotta objects;
- irregular breaks;
- porous surfaces;
- vertical elements;
- repairs where leaks must be avoided.
For this type of support, the cyano GEL glue offers a particularly interesting level of control.
Why does terracotta require a suitable glue?
The main characteristic of terracotta is its porosity.
When something breaks, the edges may also be uneven and covered in dust. These two characteristics directly influence the quality of the bonding.
Before any repair, it is therefore necessary:
- remove dust and particles;
- check that surfaces are dry;
- reposition the pieces without glue;
- choose a viscosity suitable for breakage;
- avoid applying an excessive amount of adhesive.
This is why having several viscosities within the range superglue colle21 allows the solution to be adapted to the work actually needed.
How to glue terracotta step by step?
1. Reassemble the object before applying the glue
Start by repositioning the pieces dry.
This step is particularly important when an object has broken into three or four pieces. It allows you to understand in what order the fragments must be assembled.
2. Clean the break
Gently remove dust and small loose fragments.
Surfaces must be clean and dry so that the glue can adhere directly to the terracotta.
3. Choose between DENSE and GEL
For a relatively clean break, use the DENSE cyano glue.
For a more porous, irregular or vertical surface, choose the cyano GEL glue.
4. Apply a small amount of glue
Adding more glue does not automatically mean better bonding.
Place a controlled quantity on the surfaces to be assembled. A thick or gel formulation allows for better control of the product.
5. Immediately reposition the pieces
Align the two parts correctly and then hold them firmly in position according to the product recommendations.
Avoid dragging the pieces once they are correctly positioned.
6. Let the bonding stabilize
Even when the initial setting is rapid, avoid immediately stressing the repaired object.
Allow sufficient time for bonding before returning the part to use.
How to glue a broken terracotta pot back together?
For glue back a terracotta pot, start by examining the breakout.
When the pot is simply separated into two or three pieces that fit properly, a thick cyanoacrylate or gel glue can be used.
For very porous terracotta, the FREEZE is interesting because its texture allows more product to be retained in the bonding area.
For a clean break requiring more precision, the DENSE is particularly practical.
On the other hand, for a very large pot intended to support a lot of soil or permanently subject to bad weather, mechanical constraints, humidity and temperature variations must also be taken into account.
A small decorative repair and a major structural repair do not necessarily require the same solution.
How to repair a vase or terracotta pottery?
For a vase or decorative pottery, the priority is often to obtain a repair clean and discreet.
So use a small amount of glue and avoid overflow.
DENSE allows precise application, while GEL is interesting if the edges are very absorbent or irregular.
For a piece with great decorative value, if possible, carry out a test on a discreet area before final gluing.
What other SUPER GLUE COLLE21 should you use on terracotta?
The range superglue colle21 allows you to choose different formulations depending on the repair.
FAST: for extremely thin spaces
FAST is a very fluid formulation.
It can be interesting when an adhesive must penetrate a particularly fine gap.
On very porous terracotta, however, it requires more precision than a thick formulation.
Colle21 classic: for routine repairs
Classic cyanoacrylate is a versatile solution for many small repairs when neither very thick viscosity nor extreme fluidity is required.
SLOW DRY: to have more positioning time
When several pieces need to be perfectly aligned, having more time before setting can make the job easier.
SLOW DRY can be interesting in this type of situation.
FLEX and DENSEFLEX: when the assembly undergoes more movements
These formulations provide more flexibility than a classic cyanoacrylate and can be interesting for certain assemblies subject to small movements or vibrations.
Mistakes to avoid when gluing terracotta
Do not clean the break
Sticking directly on a dusty surface reduces the quality of contact between the two pieces.
Add too much glue
Excess adhesive can overflow and make the repair less clean.
Do not test the assembly before gluing
When several pieces are present, always piece the object together without glue before starting.
Always use very liquid glue
On porous terracotta, a very fluid formulation can be quickly absorbed.
A DENSE or GEL generally allows more control.
Trying to fill a large missing piece with glue alone
When a significant part of the pottery has disappeared, simple gluing is no longer necessarily enough. A solution that also allows reconstruction or filling of the area may be necessary.
Can you glue a terracotta pot intended to stay outside?
Yes, but the conditions of use must be taken into account.
An outdoor pot can undergo:
- humidity;
- rain;
- the weight of the earth;
- shocks;
- temperature variations;
- freezing and thawing.
It is therefore necessary to distinguish a small decorative repair from a bonding that must support significant structural stress.
For a large, heavy or heavily damaged pot, a different repair solution may be preferable.
Can you repair a terracotta cup or plate?
An adhesive compatible with ceramic is not automatically certified for food contact.
For a plate, a cup or any other container intended to come into direct contact with food or drinks, only a solution must be used for which this use is explicitly validated.
Compatibility with terracotta alone is not enough to guarantee this use.
A solution also interesting for professionals
You are ceramist, craftsman, florist, decorator, object restorer or DIY professional ? Having several viscosities allows the glue to be more precisely adapted to the objects encountered in the workshop.
DENSE allows you to work with precision on a well-fitted break, while GEL is particularly interesting on porous or irregular supports. The other formulations in the range then allow you to choose the viscosity adapted to each intervention.
