Hi guys!

Just wondering if my walls are actually painted white or is it plaster? Because the wall feels chalky, does it need sealer when getting repainted? Its a BTO Premium flat if that helps.

 

take a torch light to shine on the wall. if you see the wall is perfectly smooth, then would be plaster. if you see small imperfections, would be paint due to the paint roller.

usually can just paint over the existing paint since the paint is still quite new ( I assume you just got the keys for your new BTO). sealer is more for sealing skim coat or raw plaster before painting.

@snoozeeOhhh thanks for telling the difference! I guess it's really just plaster then cause it's quite smooth. so I guess I need a sealer. 

Wondering if anyone knows how bad smelling are Expresskote fumes? Thinking of getting that as a sealer for the entire house

So, i took another look, actually it's not smooth and I found out that its a skim coat of emulsion paint, well i think I should still seal it shouldnt I?

 

Also i saw little brown dots..that were crawling on the wall. I think they may be book lice, so i think i gotta do some cleaning first using a fungicide or something ??
