Which Floor Sealer Is Right For Me?

By KleanSTONE | Jan 5th, 2019 | 0 Comments

So you have decided you need to seal your floor, but now you need to find the right sealant for the job.

There are lots of different sealers on the market, so in this blog we will take a look at the varieties, what they do and which one is right for you. 

There are two different types of sealers on the market, they are called coaters and impregnators. Coaters will simply coat the top of the stone providing a temporary barrier to water and dirt. Impregnators will penetrate the surface of the stone and line the pores, preventing liquid from penetrating, making the whole stone more durable and allowing it to retain its natural beauty. 

You can get two different types of impregnators, Oleophobic Impregnators will repel water and oil by forming a barrier in the pore. Hydrophobic Impregnators will repel water by bonding to the stone but still allowing it to breathe. Water repellent impregnators tend to last a lot longer than most sealers, high quality ones can last up to 15 years. 

 Picking which impregnator to use will depend largely on which room your floor is in and what substances it is most likely to come into contact with. Our advice would be to use an oil repellent sealer in the kitchen and a water based sealer in other rooms. If you are sealing exterior stone such as a patio or stone sculpture then a water based impregnator would be ideal. Stagnant water such as puddles will eventually penetrate the stones surface but will be evaporated thanks to the stones ability to breathe.  Using an oil repellent outside may cause water to become trapped with could result in moulding of the stone. 

In order to pick which sealer is right for you, it is important to look at the pros and cons for each and decide which factors are vital for you.

  • Easy to apply
  • Will take most of the wear and tear from heavy traffic
  • You can buy non slip coaters to increase safety.
  • Cheaper in price than an impregnator
  • Coaters are often softer than the stone itself, so can easily scratch or scuff which will lessen the effectiveness of the coater.
  • You will need regular re-application.
  • Tends to show up the traffic patterns on the floor when the coater starts to wear away.
  • Can sometimes provide a tacky, glossy and plastic finish.
  • Can block the stone ability to breathe, which cause moisture to be trapped leading to spalling.
  • Due to the fact it penetrates below surface level, it will not change the stones appearance. 
  • Will last for several years.
  • Can be used both inside and outside as it cannot be effected by light.
  • Cannot be scuffed or scratched.
  • The initial cost is higher than a coater.
  • Requires more skill to apply, so you may need to hire a professional. 
  • You need to ensure to buy from a reputable source as some solvent based impregnators release vapours on application that are harmful to the environment and banned in certain countries
