Browse Forums General Discussion 1 Aug 07, 2010 4:37 pm Hi there guys, I have what may seem like a very silly question but I will post it anyway. Our new house is nearly complete and we will have to paint the interior ourselves. The walls are brick covered in plaster. Do you need to do an undercoat or primer on the bare walls? Or can I paint straight on to them. I will be grateful for any advice as I am very new to all this. Thanks Re: Painting - Where to start 3Aug 08, 2010 4:21 pm ref_kt After my own experience painting a 24sq house all alone - use an oil based undercoat before painting. I agree. Also you can hire paint guns that spray the paint on for you. You might need to have abit of a play with them first before you go painting your walls.

Thanks Apply an undercoat yes oil based never but then again I came from a meditterranean society so oil based never been available and if you ever decide to change colour schemes. Welcome to my nightmare! Re: Painting - Where to start 6Aug 09, 2010 12:13 am ref_kt After my own experience painting a 24sq house all alone - use an oil based undercoat before painting. WHAT!! couple of things when you say plaster are you having paper faced plasterboard over brick or actual SET plaster applied over brick if it is plasterboard used a WATER BASED sealer such as Ultraprep(Taubmans) Oil Latex UC (Solver) but you can used these on SET plaster as well you can use oil based but they smell, take forever to dry, and well using water based is just SO much easier You can not use Oil based sealer/undercoat on MDF (they dont play nice) However if you have water stains in the plaster etc then you need a oil based sealer I went outside once.

Re: Painting - Where to start 7Aug 09, 2010 12:18 am here are my tips regarding what and where Ceilings - Ceiling white(Ultra flat) to all ceiling areas except bathroom and laundry Bathrooms and laundry - Satin/Semi gloss (Walls and Ceiling) better moisture resistance and can have a higher mould resistance ( you can get a Low sheen product too but coating performance is not as good IMO) Walls - Low sheen superior hiding of wall imperfections and good stain resistance Now just be aware there are different kinds if grime and the different brands tackle certain types One major brand has Superior water based stain resistance (wine, etc) while another has Superior Oil based stain resistance( finger marks etc) Most common stains are oil based so it made my choice easy (PM me for the products if you want to know) both can handle the others stain resistance but to a lesser degree Interior Trims, windows, and Doors - Satin/Semi-gloss or High Gloss ENAMEL Thats right OIL based enamel wash it up with TURPS Hard wearing, and smooth and does not flex like a Water based Gloss Sure clean up is a pain in the bum but the finish is superior Now also remember that there are varying levels of product every paint manufactuer has a Ultra premium Premium Trade Premuim Trade Budget plus Speciality finishes too So buy Ultra Premium regardless as it will be easier to apply, easier to clean, and look absolutely professional for any DIYer Also if you want the best advice face to face, Avoid big box Hardware stores and go to a Paint specific retailer (Bristol, Dulux, Taubmans, Wattyl, Luxury etc) you dont have to buy there but they should give the right advice first time So many times I have helped a customer in a Big Box hardware store as the guy/girl behind the counter had no idea whilst I was buying paint for my own projects I went outside once.

Re: Painting - Where to start 8Aug 09, 2010 1:47 am oil based sealer. semi gloss or e satin paint not flat for moist areas for colour coat. We used a satin type paint. same for everywhere. 2 shades through the entire house. make sure you have well ventilated rooms when using the sealer as it will make you ill otherwise. This time we were lucky enought o be able to afford to get the builder to do doors, door frames and ceilings/cornices so these are wall tips. wear old clothes, use a roller except from trims and wear a shower cap or hat on your head to avoid paint in the hair. paint tapes help a little but you still get bleeds. have damp clothes to wipe pain spills. ( turns dipped when sealing, water dipped when doing the wall colour. I coat of sealer and then 2 coats of wall colour or 3 if you are willing to go there. .

My sister's place was done in oil based sealer, mine in a water based sealer. Paint over the water base sealer showed every run, drip etc of the sealer - not to mention took 3 coats of paint to cover effectively. My sisters place didn't show any drips or runs and only required 2 coats of paint to cover the walls effectively. Yes the oil based has more toxic fumes and requires turps to clean things, but the paint job was a lot easier and has much better coverage then the water based sealer.

If you are applying the sealer properly there should not be any runs or drips as the sealer is asorbed by the plaster and fills the pores allowing the top coat to be applied to achieve an even finish but yes an oil based sealer is thinner and is more readily asorbed When you had to paint 3 coats of top coat what colour and product did you use Ref Kt?? I know when I painted a wall in my house in a rich red (mind you it was red from the factory) that it took me 12 coats thats right 12 coats (does look good though)But for Pastels and off whites 2 topcoats are more than enough IF you have a ULTRA PREMIUM product some of the cheaper brands and products do not have the covering power and will make you do multiple coats to achieve a satisfactory result I have seen a BUDGET can of white paint take 4 coats to cover a off white By all means feel free to use oil based but you can achieve the same results with a water based product why suffer nausea, dizzy spells, and headaches from high VOC product??? I feel semi gloss/satin walls is overkill when a Ultra-premium LOW sheen has better hiding and can have similar stain resistance and looks SO much nicer But stay away from flat paint on walls it is hopeless totally hopeless I went outside once.

Re: Painting - Where to start 11Aug 09, 2010 3:32 am Oil based sealer was a recommendation by a professional painter my dad knows, after we had started with the water based one. It was solver paint, colour was Solver Whitetone which is an off white colour. Djembe asked for advice - I gave advice I wish I hadn't be to late to take based on my own experience.

Re: Painting - Where to start 13Aug 09, 2010 5:24 pm I've spoken to my friend who will be painting my house and she recommends (in summer) a minimum of 3 months drying time or 6 months in winter, followed by an oil based sealer. But the longer you can leave the walls to dry out, the better. Re: Painting - Where to start 14Aug 09, 2010 9:08 pm Huggy_B I've spoken to my friend who will be painting my house and she recommends (in summer) a minimum of 3 months drying time or 6 months in winter, followed by an oil based sealer. But the longer you can leave the walls to dry out, the better. yes for the plaster good period of drying before painting I did a little more research regarding using the oil based sealer vs water based on set plaster and found a few different POV on sealing but seems that oil sealer is better alternative (I spoke to a few old workmates) as it will bind any loose plaster as well so So I retract my previous statement regarding Water V Oil (go the oil sealer) but recommend you when you paint the sealer EVERY DOOR and WINDOW is WIDE open I went outside once.

Re: Painting - Where to start 17Aug 10, 2010 12:46 am Oil based types of undercoat have some + and water based has some + . I think thats why they invented Oil latex. I like the stuff , everyone i know who has had to sand back the walls after a spray likes it. Its great on exposed moisture sucking materials. To be honest i have never coated a whole house in oil based sealer.Its something that has never been on the spec sheets of the builders. Technology changes and paint aint just paint. If you want my honest opinion about what you should use, go the oil-latex from solver as wombat first suggested. Yes you can washout in water with Oil-Latex, impressive stuff. Hi, Have used the Dulux 1 step, oil base on my walls(white set), out of can it’s already a more thinner product than a final coat paint Also in water base Water or… 3 5016 Thanks mate, is there a standard off the shelf type breathable product I can apply DIY?
