Black oxide polished concrete floor rejuvenation

POLISHED CONCRETE FLOOR REJUVENATION

The brief was to give the existing polished concrete floor a freshen up

REJUVENATE AN EXISTING FLOOR

The existing polished concrete floor was completed by NZ Grinders many years ago.
It was time for a freshen up – we call this a rejuvenation.
It was a simple matter of going in and buffing the floor, then reapplying a stain guard.
A stunning result to this floor which was installed with a black oxide in the concrete

A tired warehouse had a new tenant – the fabulous Boheme Home furniture moved premises and needed a floor polish – an industrial finish in 400 grit satin was chosen to complement their extensive showroom aesthetic.

OLD CONCRETE REPAIRED AND POLISHED

I often get asked if I can repair less than ideal concrete. Well, the answer is YES, we can repair pretty much any concrete with-in reason.

A lot of old floors, old pubs, garages and the likes can have some pretty bad looking concrete. Underneath all that glue lays something exciting and ready to be exposed.

Here at NZ Grinders we deploy some pretty heavy tactics in bringing this type of dusty, pitted and soft concrete back to life. We make it dense and shinny, a floor the owner is proud to have.

Here we have a few pics in the slide show, showing the before then the after.

You can see that this floor was covered in old glue. We ground this off to expose the natural stone. The floor looked terrible with extreme pitting and holes.

Using special chemicals we hardened the floor. This floor was given special care and attention. We then used a solution to pit fill the floor to a glassy finish without any holes. You can see this in the next photo. We then polished the concrete and added a full stain protection polish to give the stones their  natural hues.

POLISHED CONCRETE

This job was polished concrete Auckland for a residential property.  We needed to grind and polish the floor for an indoor/outdoor swimming pool area.  All control joints had to be tidied up by re-cutting and filling.

The result was a 50 Sq/m concrete floor took shape rather quickly. All control joints were pre-filled and then the grinding process took place to expose a  heavy consistent grind. We found the concrete grind had left the floor with lots of air pockets. We carefully filled these. The floor was then harden and taken to a 800 finish with high detail given to corners and edges. A water based polished was then burnished into the floor to give the shine and luster the customer ordered.

EPOXY COATING

Whitaker Construction asked us for a hygenic epoxy coating system for a new toilet facility for the council.  We coated the floor in a 10 year warrantied coating system that can withstand constant foot traffic and cleaning. A specific colour was also chosen.

We ground and prepared the floor. A high build solvent free epoxy was used to prime the floor using vinyl flakes to give texture and depth and anti slip. The floor was then over coated using BASF’s high build epoxy system. This gives the floor a very high abrasion resistance.

VICTORIA PARK PROJECT – CONCRETE GRINDING

This project was the Auckland Council’s Victoria Park alliance project with Fletchers, Concrete grinding or honing for basketball court.

Fletcher Construction required a safe dust free environment while concrete grinding to show the natural stone and to provide a slip co-efficent rating of +.6.

The concrete mix was a combination of sea shells and river stone combined with exposed aggregate. Our job was to grind certain areas and seal the concrete in an invisible sealer to provide protection from the elements.

The project went smoothly and quickly with NZ Grinders removing 1.2 ton of concrete grinding dust from the site in 12 hours.  Attention to detail was given around bollards and ramp areas plus the impressive circle ground for the 3 point score line for playing basket ball.

PUKE ARIKI MUSEUM NEW PLYMOUTH

The project was the exhibitions area, approximately 450 sq/meters – Remove old concrete sealer and polish to give a robust concrete polished finish that compliments the art on display.

Requirements: Grind off existing epoxy sealer. Leave the natural cracks and joins in the concrete. Then diamond polish to give a rustic but elegant finish that has good light reflection and compliments the modern design of the museum. All concrete grinding was to be completed in a completely dust free environment due to the sensitive nature of existing pieces in other areas of the museum.

Our first exercise was to remove the existing coating, level and flatten the floor. There was a heavy emphasis on being dust free while grinding. We achieved this with our state of the art vacs that let us dry grind.   We also found extensive water damaged concrete that was caused from rain at time of pour that required special chemicals to harden and strengthen. With our strong grinding team we made it happen with-in the tight working-time frames to deliver the floor back to the New Plymouth Council within the required 3 days. The gloss shine is a brilliant semi satin finish that is proving to be excellent for the council’s needs.

POLISHED CONCRETE FOR FRESHER

The project was polished concrete for a supermarket.

POLISHED CONCRETE – FRESHER

The project was Fresher  – Polished concrete for supermarket

Using grinding and concrete polishing to create a flat diamond ground floor that is able to be cleaned and is presentable and tidy to the public.

The 500 SQ/M floor had intense carpet glue that had to be removed with diamond blades, even before polishing could begin. A light grind was achieved without showing too much stone. The floor was taken up to a 400 finish and then protected with polish that was burnished into the concrete substrate. The job took 3 days. The result is a satin finish that is customer friendly, clean and tidy. A must for supermarkets.

POLISHED CONCRETE STIRLING SPORTS

POLISHED CONCRETE – STIRLING SPORTS

The project was a refurbishment floor for retail sports store concrete grind and polish.

To remove the existing flooring glue and overlay on approximately 300 sq/meters. Fill existing holes and polish the 50 year old concrete to give a rustic concrete polished floor appearance that is suitable for a retail outlet. Time frame given 4 days.

Our first exercise was to remove the existing coatings, level the concrete and flatten the floor. We used a mixture of all our machines – even thou there was a large amount of floor space, it was broken by many column supports. The concrete was soft and needed a lot of hardening to create a surface that could be polished to be dust free. Even thou the floor is 50+ years old and soft,  the result has been fantastic.

EPOXY & POLISHED CONCRETE VAN DYCK’S

The project was Van Dyck’s concrete polish with stain colouring, full stain protection, coving and epoxy coating for mixing room

EPOXY & POLISHED CONCRETE – VAN DYCK’S

The project was Van Dyck’s concrete polish with stain colouring, full stain protection, coving and epoxy coating for mixing room

Using a colour stain system with solvent based polish from Superfloor, we were to polish 700 sq/meters for protection against food spills and to be easily cleanable and slip resistant. Epoxy floor coating was also needed in the mixing room. The epoxy floor was done in BASF Mastertop 1080.

This project used a mix of different flooring systems. Ramps and coving made from resin and polished concrete for the factory floor. The polished floor was shaved to produce a bronze Superfloor finsh. All control joints were correctly filled to move with the 30MPA concrete without failure and provide a simple hygienic solution that made the floor cleanable. The customer Marcel was so impressed with the results we did another 500 sq/meters. This brought the other areas of existing concrete floors up to a cleanable polished concrete system.

All the coving was done in concresive 25/25 with a arrow head, this was joined into a chase 10mm cut to anchor the coving to the floor while still retaining the polished concrete.

The epoxy mixing room was done in a epoxy paint system to save money instead of the usual screeds

We are very please with the results and the job flowed smoothly with no issues of time restraints

Grind the top surface only and produce a water proof polished floor that can handle high foot traffic and food spills.

Working within another tight time frame of 2 days our team produced exciting results of shine and beauty. The floor was gently ground to remove only a small fraction of the surface to give a salt and pepper finish the best we could with the concrete supplied. The floor was treated with a methanol based polish to stop food and liquid spills from soaking into the pores of the new polished concrete, an important aspect for this job.
