How to Clean Substrates before Bonding

Have you ever wondered if a substrate needs cleaned before bonding?

If so, you’re not alone – it’s actually one of the most frequently asked questions we’re asked by inexperienced bonders.

Quite simply, the answer is yes, the substrate SHOULD be cleaned beforehand.

Importantly, however, there’s a right way to do it and a wrong way to do it, which is why we’ve compiled some handy tips to walk you through the process.

To begin with, a substrate must be dry, clean and free from oil, grease or other contaminants before you apply any bonding product.


Because a grimy substrate will result in a bond that’s decidedly below par – and that’s far from ideal when you’ve shelled out hard-earned cash purchasing the product.

The Best Way to Clean a Substrate

To avoid a scenario like the above, you should be familiar with the best way to clean your substrate.

One of the simplest ways is to use a fast drying, solvent-based wipe to remove dirt, making sure to avoid white spirit or an oil-based cleaner altogether.

While white spirit is handy when cleaning other items, if used on a substrate it’s likely to react negatively with the adhesive, which can lead to bond failure.

Instead, keep your eyes peeled for a proprietary solvent cleaner.

In addition, it’s also advisable to avoid natural citrus cleaners, as the residues can cause a negative reaction, causing your bond to break down.

While our range of adhesives are engineered to ensure you achieve the best results, it’s vital you know how to use them in the way they were intended.
