I was really wary about using Dulux Easy Care after reading reviews on mumsnet and elsewhere online.....but I really wanted to wipe marks off the walls without the lovely matt finish going shiny.
Dulux Customer Helpline gave great advice :-
Prepare the suraface. We were painting over ordinary Dulux Matt emulsion which was fine but don’t paint directly over ‘soft sheen’ cos it won’t grip.
Even painting over matt emulsion, we sanded lightly over the whole surface to ensure a ‘key’, followed by washing down with ‘sugar soap’ solution and rinsing with plain water.
We turned the heating off in the room and put strips of newspaper over the window glass to keep the glaring sun out (south facing room)
As advised, we stirred the paint gently and cut in around the edges of just one wall at a time, before filling in using a decent synthetic (but not foam) roller for the main parts of each wall and let it dry completely for 4 hours.
Because I was still nervous about this paint, based on bad reviews from experienced DIYers, we very lightly sanded, washed down with weak sugar soap solution, rinsed and allowed to dry thoroughly.
For the second coat we changed tack and cut in all the walls then left it to dy completely overnight. Next day we filled in all the walls with the roller (it had been kept wrapped in cling film since the first coat)
First and second coat went on like a dream with roller and brush, lovely paint, creamy and covers well. Amount of paint on the roller is important - not too much to be drippy, not too little that it won’t spread,
It is also important to work fairly quickly, not a mad dash but don’t dawdle and don’t go back to a previous section because, once its tacky, it won’t like being rollered again.
Once the second coat is dry, the surface finish is perfect. We’re really pleased with it. Don’t know yet how it will wear but thought it was important to give a view on its application in case other people are unsure about using it.
