Episode 99 Epoxy Floor Treatment: Shield-crete

Episode 99 Epoxy Floor Treatment: Shield-crete

So what did I do in the shed today?

Nothing much. Unless you count surfacing the floor that is!




It took almost 4 hours, and almost every bit of epoxy from 3 kits (I might have had about 1m2 of epoxy left, if that. Either I went with a heavy coat, or the surface was significantly more porous after the acid etch. Not a problem- either way (and most likely both), it will be a better finish because of it.

I might have been a bit heavy handed with the paint flakes, but it is personal preference- either would be a good option.

Tomorrow I will apply the glaze, which will seal the vinyl paint chips in, while finishing off the floor coating (and it will have some non-slip agent stirred through- provided in the Shield-crete kit).

Video coming- once glaze is added to the footage recorded. Oh, and note to self- the GoPro does not change exposure settings during a video, so if you start a time lapse early morning when it is quite dark, the resulting footage will be too overexposed by 11am!

I would have stopped recordings during camera moves, but a. I didn’t know this fact before now, and b. while applying the epoxy, my hands became so sticky with epoxy (and paint chips!), if I had touched it, the GoPro would have become a permanent fixture!

Concrete Makeover

The shed is coming along quickly now, and so it is time for some thought to be given to the concrete slab.  Sure, it has been cast and finished well, but there is something more that I want to do with it.

The inspiration initially came from seeing the floor of Marc (The Wood Whisperer) Spagnuolo’s new shed and floor.  It looked like a million bucks.

A friend then recently mentioned that there was a sponsor of the Australian Woodwork Forums that had a product that might be worth considering, and the idea quickly germinated, as it was just what I was looking for.

The company is Globak Woodcare, and among the other products they have on offer (including Miniwax wipe-on poly and other interesting products for woodworking), they have Shield-Crete for concrete floors (be that garage, shed, etc).

I was always intending to seal the slab, but this achieves that in style.

The hardest thing was deciding on the colour, but in the end I have opted for Ivory.  Each pack of Shield-Crete will cover 20m2 according to the description, so hopefully I can push it that extra 5 – Steve from Globak thought so, but I’ll double check with him before I start!  There are extra beige and ivory flakes to add, to give good coverage of the colour, adding depth to the floor.  The Shield-Crete is a 2 part epoxy – this is not a painted floor effect!

In the pack there is a packet of powder to give the finished surface grip, and a degreasing agent (more important for coating floors that have already been in use, but I’ll prep the surface with it anyway).  It is interesting to read about how to coat existing garage floors, where cars have already been parking on it.  The chemicals in the tyres will have been leaching into the concrete surface, and if you have been using a wheel polish, that is silicon-based so these floors need a bit more preparation before the epoxy can be applied.  Any floor that has previously been sealed (which is very hard to spot just by looking) also needs extra consideration.  If you drip some water on the concrete floor, if it forms droplets on the surface, this is a fair indication that it has been sealed.

Fortunately for me, I haven’t sealed my slab yet, so I don’t have to do an acid-etch, sand etc.  Not that these are difficult, it is just a bit more work if needed.  Down track I may do the garage floor as well, and that will definitely need extra steps.

The application of the Shield-Crete is pretty straight-forward – it is applied with a paint roller.  The flakes are then rained down on this surface (throwing handfuls into the air – there is a video demonstrating this on their website).

You can leave the finish here, but to really complete the surface (and that is what I am aiming for), a clear acrylic glaze is then rolled over the top.  This gives a better finish, and locks the flakes into the surface better.

I’m not sure at this stage when I will apply the epoxy to the concrete – it is all a matter of timing, between when the shed is finished, and to give it the 48 hours to harden before I start moving into the shed.  Ideally, if the shed can be finished on Wednesday, I will be able to apply this Thursday morning, so it will be ready for the weekend.  However, whatever happens I need to apply this to the concrete before I begin using the shed, as it would be impossible once the machines are in there (and especially when I start making a mess (no, I am not going to make a mess, I am going to keep this shed clean – repeat 3 times!)

The finish will look something like this

The slab becomes a reality

6am start, with the cement truck arriving at 7:30.  It may have been drizzling to start, but the day sure cleared up by the end.  Irrespective, a pump truck was used to get the 6.4 m3 of concrete on site. Made the job go very quickly.

So it is in and done.  The expansion joints will be added tomorrow (done by saw, rather than trowel).

It can be walked on tomorrow, and built upon in a week.  Given the shed is a week away on Monday, the timing was getting pretty tight in the end (although there will still have been a few days grace as the erectors won’t be on site the day the shed arrives!  I’ll soon be able to take delivery of the SawStop as well (finally!).

Shed Progress (sorta)

Bit more waiting required before things are locked in – perhaps Monday.

In the meantime, the Report and Consent is still with the council – they indicated they may have a response by today (which presumably means in the mail, so again early next week to hear how it is progressing, and if there is any further work required).  My phone call to them last week didn’t throw up too many issues, but I’ll know more when I get their official response.  I am hopeful.

Had a concreter out today for a quote – again they will put it together over the weekend.  Looks like the potential for a lot of news on Monday, but I’m not pinning too much on that likelihood!  One thing to say – this was the first concreter even willing to turn up to quote.  I equate it to standing at the side of the road, waving a cheque book (or cash) and no one interesting in taking my money.

At least these guys sound competent.  Will be interested to see their quote!

9 Minutes

Another small milestone has been passed – I now have an exact partslist and specifications sheet for the shed, along with a diagram of the required slab and footings.

Interesting point – the structure has around 2900 fasteners (majority self tapping screws), and will weigh almost 2 tonnes (not counting the slab obviously!)

The concrete slab (including footings) I have calculated to require 6m3 of concrete – approx 13 tonnes (wet).  That allows 100mm thick slab, with an additional 300x300x300 footing under each column, and 300x300x500 footings under each column that supports the mezzanine.

Time to start looking at concreters, and finding out about pump trucks.  Also, I want to have a chat to an electrician and plumber to see what needs to be considered before the pour, because once the slab is down, there is no adding electrical ducts, drains, or under-floor dust extraction.

Finally – so much to think about!
