  • Essential Preparation for Painting Bare Concrete


    Floorsaver floor paints are designed to last for years, so the last thing you want is a problem with adhesion. Floorsaver Floor Etcher cleans, etches and opens up the pores of bare concrete, giving your paint a sound, keyed surface to grip.

    Ideal for new or dirty bare concrete floors, it removes the gritty, dusty surface layer, neutralises alkalinity on new concrete and lifts ingrained dirt, leaving a clean surface that is ready to paint.


    Why use Floorsaver Floor Etcher?


    • Removes the gritty, dusty surface that paint would otherwise stick to, so the paint doesn't break away from the concrete beneath
    • Keys the surface, making the concrete slightly porous so paint can penetrate
    • Neutralises alkalinity on new concrete (less than 6 months old), which single pack floor paints don't like
    • Lifts ingrained dirt and dust, leaving bare concrete looking much "whiter" and ready for painting
    • Ready to use as supplied, with no dilution needed


    Ideal for:


    • New bare concrete floors before painting
    • Old, dusty or dirty bare concrete
    • Garage, workshop and warehouse floors before painting


    Where to use:


    • Bare concrete only


    Not suitable for:


    • Painted or sealed surfaces, where it is ineffective
    • Sand & cement screeds
    • Self-levelling compounds


    Coverage:

     

    • 5L covers approx. 15-20m²

     

    There are 4 good reasons to use floorsaver Floor Etcher.

    • Concrete often has a gritty dusty surface. If you apply paint to it, the paint will stick to the grit, but the whole lot will break away from the concrete beneath. floorsaver Floor Etcher removes this.
    • Concrete should be slightly porous to allow the paint to penetrate. floorsaver Floor Etcher keys the surface to make this happen.
    • Single pack alkyd based paints, such as floorsaver Floor Paint, do not like high levels of alkalinity. New concrete (less than 6 months) is alkaline and floorsaver Floor Etcher neutralises the surface alkalinity.
    • floorsaver Floor Etcher is a diluted hydrochloric acid based liquid, which is great for removing ingrained dirt and dust. If used on dirty, bare concrete the concrete will end up looking much 'whiter' and it will look like a surface which is now ready to be painted.

  • Application

    Only use on "Bare Concrete", it is ineffective on painted or sealed surfaces.

    • Tip into a plastic watering can fitted with a plastic rose and apply evenly to no more than 15-20m² at a time
    • The etcher froths as it hits the concrete. This is the acid base reacting with the alkaline concrete and biting into the surface, removing impurities and keying it.
    • Scrub with a stiff broom, or hire a scrubbing machine for large areas
    • When the frothing stops, the etcher has done its job. Any solution left on the floor has been neutralised by the reaction.
    • Scrub and flush with clean water before the etched surface dries, to remove all the residue
    • When the surface is dry you can apply Floorsaver Floor Paint. If you're using Floorsaver Epoxy Floor Paint, it doesn't matter if the concrete is still a little damp from cleaning.

      Top tip:
    • Use a watering can with a rose. If you pour the etcher straight from the can, you may be left with "acid scarring" where the concrete has been unevenly etched, and this may show through the paint.

      What if it doesn't froth?
    • If the etcher doesn't froth or react, the surface is probably sealed and should be lightly abraded to give a key instead. It could also be that the concrete is so smooth, dense and hard that the etcher can't penetrate. In that case the floor may not paint well either, so please check with our team for advice before you start.

      Never etched concrete before?
    • Don't worry, it's a simple job: apply, scrub and rinse.

QUESTIONS & ANSWERS

Ask a Question

  • What is the dilution rate

    This should not be diluted. Please apply it directly to the surface, as supplied.

  • Hello I have a bare concrete floor in the garage that I’d like to use as a home gym. It gets really dusty so is there a solution where I don’t kit the garage out and then my gym equipment gets dusty.

    Hi,

    On a new concrete surface the dust is often surface laitance, This is when fine particlaes that have risen to the top of the surface during the drying process have simply resettled. Often they create a constantly dusty finish to a concrete floor. In fact, this can easily be removed using our Floor Etcher. This is used to remove the very top layer of the surface which is loose and dusty and expose the harder surface just below.

    Once complete you can then either paint the harder floor you are left with, for a dust free and clean finish, or simply user a clear penetrative sealer. Our Concrete Dustproofer would soak in and stop the floor from conitnuing to dust up without siginificantly changing the appearance.

    Kind Regards,
    Michael

  • Is this suitable for use on a new (dusty) concrete slab before applying sealer?

    You could use it for this purpose, but it isn't necessary. The Concrete Sealer will bind the dust together and prevent the floor dusting up again.

  • We need to paint the floor of our garage with a hard wearing epoxy paint, what would you recommend? We are after a semi gloss, grey finish. We're moving into a new home (New Build) and it has an attached garage and we want to paint the floor with a hard wearing epoxy paint. Can you recommend what we need and how we should proceed? It's a single garage and we're after a grey semi gloss type finish. Thanks

    If the concrete is new use our Floor Etcher first, as this will remove surface laitance (a dusty layer) and it will slighly open up the surface of the concrete so the epoxy paint can bond to it.  Epoxy Floor Paint is really hard wearing and it's between a semi - high gloss finish (depends on the porosity of the concrete) and comes in both light and mid grey.  See our data sheet for colour swatches and step by step preparation, application, etc.

  • I have a concrete garage floor that was "sealed" many (20+) years ago which has then been painted over at least twice. The existing paint sticks to car tyres and lifts away if a car is parked on it for a couple of days or more. There are only a few patches where the concrete is exposed, and 5L of etcher would be way more than I'd need - is there another solution that will ensure that a fresh coat of paint over the top of the existing and onto the exposed concrete will stay down?

    Thank you for your enquiry. We do not advise using the etchant on a previously painted substrate. We would advise that the substrate is abraded to remove any previous coating/sealer before the applying a 2 pk coating.

  • How many square feet does your Floorsaver Etch cover. Do you have to dilute it or use it straight from the container? Regards John.

    Hi John, this will cover 20sqm and you do not need to dilute it. Please see Floor Etcher - 5L - concrete etching surface preparation and cleaning – floorsaver
