Why is my epoxy still sticky?

The usual problem is an incomplete mix or the wrong resin-to-hardener ratio. Scrape the sides and bottom while mixing, and measure both parts exactly as that product directs; adding fresh epoxy over a soft layer only traps the bad mix underneath.

Will extra hardener make epoxy cure faster?

No. Epoxy needs its stated chemical ratio, and changing it leaves unreacted material in the joint. If you need a faster cure, choose a faster formulation instead of altering the mix.

Can I use epoxy when the two parts do not fit perfectly?

Yes, within reason. Epoxy can bridge an irregular joint, but it still needs clean, scuffed surfaces and enough contact area on both sides; a large unsupported blob is filler, not structure.

Why did epoxy pop off a flexible repair?

Cured epoxy is rigid, so repeated bending concentrates stress at the edge of the glue line until it cracks loose. Use a flexible adhesive when the materials are expected to fold, stretch, or move against each other.

Utilisation

Comment utiliser Époxy

01Mélangez soigneusement les deux composants — un époxy mal mélangé n’atteint jamais sa résistance maximale.
02Dépolissez les surfaces lisses et dégraissez pour que la résine puisse accrocher.
03Serrez modérément ; un joint de colle mince et régulier est plus solide qu’un joint épais.
04Laissez durcir complètement avant de mettre en charge — « pris » ne veut pas dire « durci ».
