I know this is an old thread but it was useful advise regarding the use of sugar soap.
I read the comments on gloss paint yellowing etc with interest, plus the reference to Dulux paints. I feel the need to pass on some personal advice based on experience.
Last year I redecorated my bedroom following an en suite conversion. At first I used a Dulux undercoat for a gloss finishing coat. The smell was indescribably strong and persistent, driving us to move bedrooms for over a week.
I returned to Homebase and looked for low odour paint, gradually being attracted to water based products that also claimed to be non yellowing. An attendant, good old boy, advised me to avoid Dulux water based satin finish like the plague. He said that no water based paint would adhere to previous oil based paint, would run and when dry would peel off. I knew that a neighbour had used just that product so I borrowed a half full tin and tried it on a well sanded door. Well, it was horrible to use, being very runny, but I persevered. It also looked very light on pigment in the tin, sort of see-through! I was then astounded to discover not the silk finish promised, but a gloss so bright that it reflected like a mirror. It didn't peel however. For all these reasons I started Googling for water based, satin finish paint.
The first thing I found was a forum where the Dulux paint I'd used was slated by dozens of people on page after page. Then I found a professional painter and decorator website. One chap, backed up by others, recommended a Sikkens paint with the hard to remember name of Rubbol BL Satura. More Googling revealed that this Dutch product was actually made in the same factory as Dulux. However, having once used Sikkens paint on a boat, and having been a fan of beautifully painted Dutch houses, I was prepaired to give it a try.
I scouted around for this and discovered it was stocked by a firm called Brewers. Their website had a nifty nearest branch finder, so I rang up about the paint. The smaller branches didn't stock it but the main one in Poole did. I drove down, bought the paint and some nice synthetic brushes and as well as getting lots of good advice, was amazed to be told that in future I shouldn't drive so far, but just ring and they would deliver....Free!!
I used the paint. It looked very highly pigmented and was easy to use as long as I was a bit careful not to over apply it, though any runs could be quickly brushed out. It can be used indoors or out. I soon got used to it and painted without any runs at all. It covered very well indeed and dried extremely quickly, being dust dry in 1-2 hours and recoatable in 5 hours, should that be necessary. Only the odd bit of door surround required a second coat. It was so odourless that we slept in the same room unbothered. It is a tough polyurathene product and, being water based, is free of the Iodine based additive that EU regulations insist is in all oil based paints, so it will stay white. Oh yes, it produces a lovely white soft satin finish. After a year it is unchanged, cleans easily and not peeling at all. I am about to use it on the 11 doors of my hallway. Wish me luck.
Oh yes. I'm sugar soaping the very dirty downstairs doors and surrounds prior to sanding and any recesses upstairs that are difficult to sand into. I want it to last and be absolutely sure that the doomsayer in Homebase doesn't get the last laugh.
