MR. JO Artglue — CG50
The balanced, moderate-cure gloss that makes large flat work look effortless
Hook — late-afternoon at the workshop
Meera runs a small studio that makes decorative trays and wall panels. She gets commissions for large, flat pieces — sometimes 2–3 ft across — and every time she pours a glossy topcoat she battles the same headaches: streaks from rushed spreading, random dimples from popped bubbles, and long cure times that force her to hold up shipping. She needs a resin that gives enough time to spread perfectly, levels without fuss, and cures reliably so she can finish and ship on schedule.
If you do flat panels, tabletops or large trays, Meera’s problem is yours too.
The problem — why flat surfaces are deceptively hard
On large, flat pieces you face a different set of issues than with small or curved objects:
- Too-fast resins level poorly and lock in brush marks or streaks.
- Too-slow resins increase dust pickup, extend turnaround time and risk substrate contamination.
- Bubbles and dimples are more visible across a wide surface and ruin the glossy look.
- Uneven thickness causes patchy gloss and may require heavy sanding or recoat.
These problems cost time, materials and reputation — and they’re usually caused by choosing the wrong resin for the job.
The solution — why CG50 is the right fit
MR. JO Artglue — CG50 is formulated as the moderate-cure, balanced member of the Artglue family. It gives you enough open time to spread and level large flat areas evenly, while curing quickly enough to reduce dust and speed up production.
Core advantages:
- Moderate working window — spread confidently without the panic of ultra-fast gels.
- Good self-leveling — minimizes brush marks and streaks on flat panels.
- Hard, glossy finish — deep shine that polishes beautifully.
- Predictable cure — shorter overall lead time than slow systems, fewer rejects.
In short — CG50 lets you control the pour, not the other way round.
How to use — a practical workflow (Meera’s preferred method)
- Prep the panel: sand to final grit, remove dust with tack cloth, and ensure substrate is dry and free from oils. Mask the edges if you need clean drop lines.
- Measure & mix: follow the TDS mix ratio. Mix slightly larger batches for a big panel but avoid huge volumes (exotherm risk). Stir gently and consistently for the recommended time.
- Degas (optional): for showroom pieces, degas mixed resin briefly under vacuum or let it sit 2–3 minutes to let entrained air rise.
- Pour & spread: pour in a zigzag and spread with a notched trowel, squeegee or soft spreader to achieve even coverage. Thin pours (1–2 mm) level best.
- Bubble control: pass a heat gun or small torch quickly and at a distance to pop surface bubbles — short bursts only.
- Cure: leave in a dust-free area. Initial skin forms in the CG50 moderate window; full cure as per TDS.
- Finish: if you need extra depth, sand lightly and apply another thin coat. CG50 sands and re-coats predictably.
Dos & Don’ts — quick field rules
Do:
- Use slightly warm workshop temps (within TDS limits) for consistent flow.
- Work in a clean, low-dust environment.
- Mix only the volume you can apply within the working time.
- Pop bubbles immediately after pour.
Don’t:
- Don’t over-stir or whip air into the mix.
- Don’t pour very thick in one go — multiple thin coats beat one thick coat.
- Don’t rush spreading; take the 5–10 extra minutes CG50 gives you.
Troubleshooting — common issues and fixesons
- Persistent bubbles: reduce mixing speed, let mix rest 1–2 minutes before pouring, use light heat after pour.
- Fish-eyes / uneven wetting: substrate contamination — re-clean surface and test adhesion on a scrap.
- Dust trapped in cure: increase cleanliness or use a dust-cover tent for the cure period.
- Matty finish in spots: likely uneven thickness — sand and apply a thin finishing coat.
Artisan takeaway — Meera ships on time
Meera switched to CG50 for her flat trays. She spreads confidently, gets a uniform glassy surface, and finishes faster with less sanding. Her customers notice the depth and clarity — and she spends less time fixing mistakes.
If your work is large and flat and you need a dependable, easy-to-level gloss without a snail-pace cure, MR. JO Artglue — CG50 is your go-to.
