I need to plaster a wall. The picture of the wall can be found on this link: //www.diynot.com/network/BorisBollok0v/albums/6601/26416
Area of the wall: 4m squared
Maximum thickness of the palster to eb applied: 10mm
Plan of action:
1.) Sand the wall, clean with brush, apply primer coat (1 part Unibond PVA to 5 part water)
2.) Undercoat: apply 2 coats of Thistel Hardwall upto 7mm
3.) Finish-coat: 1 coat of Thistel Multi-Finish upto 3mm
Q1.) I have chosen Hardwall instead of Bonding because I belive that those bricks have high suction, is that a correct assumption?
Q2.) Is my plan correct or does it need any improvement?
Q3.) What the hell is keying and how is it done??? I keep reading that the hardwall coat needs to be lightly scracthced before applying multi-finnish. I read on one site and it suggested to use a nail to scratch the plaster another site suggested using a plank off wood. What do you suggest?
Q4.) If I created a key on the Undercoat would i need to apply (1 part Unibond PVA to 5 part water) before skimming with multi-finnish.
Thank you very much for your input.
