Great build. Tech specs seem to point it could be used in small to medium molds without adding anything. From Sika
■ Minimum application thickness (neat without additional aggregate): 25 mm (1 in). ( less seems fine for what we are doing with spheres) ■ Maximum application thickness (neat without additional aggregate): 150 mm (6 in). Thicker applications are possible with the addition of suitable aggregate. Please contact Sika Canada Technical Services.
I also found it tends to creep if to wet. Reminds me of non newtonian fluid vids on YT. Again from Sika
■ Versatile, can be applied in any consistency from dry pack to fluid by varying water content. ■ Reducing water content accelerates strength development and ultimate compressive strength values.

Very nice. Here is my offer. You send the bunny and I'll pay the postage. I will send ( I'll pay postage to you) my hedge hog mold as a loner. You can make a few castings and do with what you like with said castings (wink). Once you have a few castings send the mold back to me at your cost. I will also put in a few plastic molds in with the loner mold. If this is to your liking PM me for address exchange and payment arrangements. If not feel free to counter offer. Thanks

Nothing like saving a build. Chip-board holder is clever. Looks like the resurface is working for you. Next time you go shopping you might try something different? I think Gris uses same brand but a top coat mix? If you have a Rona closer the Bomix parge mix and the stucco mix seem to bond & work well too. Mind you tough to change product if its working. I still think QW is the best base layer mix. Now if I my 1:1:1 ratio of QW, fine sand & portland experiment survives the freeze thaw this year that might be my new go to. Cuts costs and found it easier apply & better finish. Thanks for posting.

Is there a concrete or building supply store near you? Look for a place that concrete guys buy from. Be it for flat work or countertops. For example here are 3 locations that I deal with. This might help for key words when using google to search in your area.

Balls-aching may be a understatement. Sometimes builds just don't go our way. No expert but this is what I do. Inflate ball till firm but not hard. When applying QW I push in and up ( or down) on the tape to force it into the tiny squares. Sphere does looks good none the less.
Trying out a new product. At 24 hours the feather edge is strong. Has a polymer sheen to it.
What's different about the zika grout 212 as opposed to other grouts?
There are 100's of grouts on the market. I choose this as it was available locally. This is also a cement grout used in construction opposed to a tile grout. Other details I like are below. You should be able to spot the pros when it comes to what we are trying to do with spheres.
SIKAGROUT® 212 High Quality, Well Proven, Versatile and Non-Shrink, Cementitious Grout USE On grade, above and below grade, interior and exterior applications. Structural grouting of column base plates, machine base plates, anchor bolts, bearing plates, bridge seats, precast wall panels CHARACTERISTICS AND ADVANTAGES Pre-blended for easy application and maximum field control. Just add water, mix and place. Versatile, can be applied in any consistency from dry pack to fluid. Non-corrosive does not contain chlorides. Formulated with inert, non-reactive aggregates to eliminate potential Alkali-Aggregate Reactivity (AAR). Excellent pumpability - does not segregate even at high flow; no build-up on equipment hopper. Low heat development. Superior freeze/thaw resistance. Ministry of Transport Ontario approval for use in grouting bridge bearings as well as anchor bars. (Reports MI-110, MI-120 respectively). Meets Ontario Hydro specification M-690-87 for pumping through grout pump and hoses for adistance of up to 60 m (196 ft). Ministère des Transports du Québec acceptance for grouting anchor bolts and reinforcing dowels in concrete. Approved by the Alberta Ministry of Transportation Meets H. A. Simons grout specification 1S-05.01 for grout types 1, 2a, 2b, 2c, 3 and 4. Meets ASTM C1107 for Grade C type grouts. - See more at: can.sika.com/en/residential-construction/home/products/repair-and-resurfacing-of-concrete.html#sthash.HF5JraDi.dpuf
Wow Gunz that sprayer looks really cool it would come in handy for some of my projects. Di you think it would work as well on expanded metal lathe👍
Thats the main use of it.
I'm wondering if this might be a cheaper alternative? You would have to tweak your mix? This is a specific brand but the tool is a texture sprayer. Never used one. $125 at a Canadian Home Depot. vs $300 US + for toolcrete mortar sprayer above.

sigh, quick google and I don't think it is available here in VA. but QW had to be special ordered from big box. maybe this can be ordered also.....
I'm trying out a few more mixes. I will say the reg mix sphere is contender once the 2 layers of resurfacer was applied. The resurfacer is just like any top coat mix made by most portland disturbers. Also think the S mortar may be a winner too? Needs a winter and some freeze thaw to know for sure.

This is a reg mix sphere with 2 layers of resurfacer. This is what I do. Don't do what I do. Wear your PPE. Don't remove guards from equipment and secure the item you're working on. I use a 4.5" grinder sometimes. Sometimes my rotozip.
