What glue to use underwater? To repair or assemble a part directly in an submerged environment, conventional glue is generally not suitable. You must choose a underwater glue specially formulated to adhere in the presence of water, while taking into account the material, the flexibility sought and the constraints of the repair.
For this type of use, Colle21 Flex Water is a flexible, transparent epoxy adhesive developed for demanding repairs and can be applied directly underwater. Its double syringe format also allows precise dosing of the two components.
Why use a specific underwater glue?
Water represents a significant constraint for many adhesives.
Glue not designed for submerged application may have difficulty adhering properly or may not provide the desired strength.
A glue underwater must therefore be chosen according to:
-
material to be repaired;
-
the permanent or temporary presence of water;
-
the flexibility of the part;
-
the necessary resistance;
-
of the environment in which the repair will be used.
Colle21 Flex Water has been developed to work on demanding repairs and assemblies, including where application directly underwater is necessary.
Which underwater glue to choose for a swimming pool?
For a swimming pool repair, the choice depends above all on the surface concerned.
Colle21 Flex Water can be used on:
-
liner ;
-
PVC;
-
EPDM;
-
fiberglass.
Its flexible epoxy formulation makes it possible to work on certain rigid surfaces as well as on materials requiring more flexibility. Once hardened, the adhesive becomes transparent, allowing for a more discreet repair.
For any major repair linked to the structure or safety of a swimming pool, it remains necessary to check that the planned repair is adapted to the support and the real constraints of the installation.
Can you use glue underwater for a boat?
Yes, provided you use a product specifically designed for this environment.
Boats and marine environments subject bonding to humidity, immersion and various mechanical stresses.
Colle21 Flex Water is intended in particular for boats, marine environments, aquatic facilities and maintenance work.
It can therefore be interesting for certain repairs where we are looking for both:
-
water resistance;
-
flexibility;
-
transparency after hardening;
-
adhesion to different materials.
How to use glue underwater?
To obtain a reliable repair, preparation remains essential.
1. Identify the material
Before gluing, check the exact nature of the surfaces to be joined.
2. Prepare the area
Remove as much dirt, deposits, dust or loose items as possible that could reduce adhesion.
3. Mix the two components
Colle21 Flex Water is presented in the form of double syringe, allowing the two components of the epoxy to be dosed in a controlled manner.
4. Apply to the area to be repaired
Apply the necessary amount to the affected area, including directly under water when the application requires it.
5. Hold and let harden
Follow the instructions for use and avoid requesting repairs before sufficient hardening.
What materials to use Colle21 Flex Water?
Versatility is one of the main advantages of this solution.
According to the product sheet, Colle21 Flex Water can be used in particular on:
-
metal;
-
drink ;
-
glass ;
-
carbon fiber;
-
concrete ;
-
ceramics;
-
cloth ;
-
neoprene;
-
PVC;
-
EPDM;
-
fiberglass.
After curing, the adhesive can also be sanded, cut or painted in order to work on finishing the repair.
Underwater glue or classic glue: what’s the difference?
A traditional glue can perform very well in a dry environment without being suitable for a directly submerged application.
The main difference is therefore the use intended by the product formulation.
With an epoxy glue like Colle21 Flex Water, the objective is to be able to carry out certain repairs even when the presence of water makes the use of a traditional adhesive difficult or impossible.
For other applications outside of water, a SUPER GLUE Colle21 cyanoacrylate, a flexible glue, gel or other specialized solution may be more relevant.
With more than 140 references, SUPER GLUE Colle21 offers a wide range of bonding solutions allowing you to choose the product according to the material and the desired application.
Mistakes to avoid with underwater glue
To maximize the quality of a repair, avoid:
-
to use a glue that is not intended for immersion;
-
neglecting the preparation of the support;
-
apply the product to unstable or detached parts;
-
to immediately request compensation;
-
to use the same adhesive for all materials;
-
carry out a structural or safety-related repair without checking the technical constraints.
The choice of a underwater glue adapted to the support remains one of the most important elements to obtain a lasting repair.
