The top 3 most asked sealer questions

Your burning questions about sealers will finally be answered.

Just because you’ve had your stone sealed in the past doesn’t necessarily mean you’re an expert on every aspect of sealers. After all, we may all own cars, but most of us couldn’t pop the hood and diagnose every breakdown or malfunction with nary a glance.

That doesn’t mean you couldn’t become better informed through by having a few quick questions answered however. The following are three of the most commonly asked questions when it comes to sealers – and the answers that come with them.

1. Can I still get stains with a sealer?

The point of undertaking surface protection with an impregnating sealer is that it will penetrate beneath the surface of the stone and prevent the ingress of water, oil and other stain-forming substances. In most cases, this will be enough to prevent damage to your stone.

However, it’s important to note that sealers only resist the penetration of these substances – they can’t prevent them 100 per cent of the time.

If allowed to sit on the surface for long enough, it will likely eventually stain. Alternatively, if it’s an acidic substance, it may cause etching of the surface. Therefore, sealed or not, you’ll want to clean spills up straight away. Use HANNAFIN Oxy-Klenza™ to be sure.

2. How long will my sealer last?

It’s hard to say how long any one individual sealer last. Not only does it all depend on the effectiveness of the sealer itself, but it also depends on where it’s applied.

A sealer will naturally lose its bonding strength and evaporate. However, there are certain factors that can hasten this process. For instance, if you’ve sealed a tile floor in a kitchen, dining room or bathroom – areas that are liable to see a lot of foot traffic – the sealer will  wear off quicker in those areas.

That’s why you need to be diligent about reapplying sealers. If you want to test whether or not your stone needs re-sealing, put water droplets on the surface of the stone. If after around 10 minutes the stone darkens, it’s time to reapply. Bear in mind that Dry-Treat sealers have a warranty of as much as 15 years when applied by an Accredited Applicator.

3. Can I simply seal my stone and forget about it?

As alluded to above, you can’t simply apply sealer and assume your stone is invincible. You still have to be diligent about cleaning up spills and stains, otherwise the money and effort you spent sealing your marble, terracotta or what-have-you will be all for naught.

Maintain the stone as you would have without the sealer being present, such as by having it undergo repairs and polishing. In addition to this, you might want to think about banning shoes from being worn on the surface, as well as choosing the right kind of furniture to sit on a stone floor that won’t damage the stone.
