Want to try Dulux Diamond Semigloss for kitchen cupboards, rather than alkyd melamine, but was concerned about brush marks and general lack of working time. Repainting our bathroom ceiling using Dulux Diamond Eggshell and Floetrol mixed 16:1 was not a success - wet edge did not hold and overlap marks were pretty severe. Had to roll on a second coat to even it out. I thought I might be OK because the bathroom is only 9' x 6'.
General consensus is that XIM Externder is better to work with than Floetrol, but I have not found a source around here (Halifax, NS). So Floetrol is my only option.
Mixed it in a ratio of 1 part Floetrol to 12 parts Diamond Semigloss, brushed it on three flush doors with these results:
- slightly better open time
- flow is a little better
- no appreciable effect on gloss
- have to work really quickly
More remarkably, the paint still dried well and when sanded 10 hr later it powdered, rather than turning to latex worms. Even with that short drying time it felt harder than the semi-gloss Aura which had previously covered these doors.
Brush was Wooster Jaguar, Ultra Firm, nylon-poly - wow, gorgeous fine filaments.
Assessment thus far: certainly good enough for the inside of the cupboards. Not quite certain about the doors and frames.
So first coat looked good, second coat is drying now. I'll wait for 10 hr or so before final judgement. I still have a litre of B-M Advance (waterborne alkyd) to try- test platform is a small table. It's going to get the full treatment - sand, fill, prime, etc.
How do people get finishes so smooth they claim they "look like sprayed"? Seems like an elusive Grail.
