Plastering help required!

Hello Tahira 1. In my experiance i would use around a 50/50 pva, water mix and apply two coats, mix up your multi finish while its drying and when its tacky apply your first coat of plaster 2. It will require no sanding at all if two coats are put on correctly. You should not wait untill first coat its dry to put on the second coat because it will dry out before you have a chane to get a perfect finish, you should wait until its like firm clay and then apply second coat that way you will have covered every thing you wanted to cover and you will have a good back round to apply your finish coat 3. I would say always remove wall paper before plastering if not the plaster can make the wall paper come away from the backround and you can end up with bumps where paper has come away from the wall and the plaster has dried leaving you with a holow bump thats will crack if touched. I hope that helps with you project and good luck. Best regards Greg GMG Plastering.

After reading all that,my advice would be to get a professional in.

Hi there. Each plasterer may have their own preferred methods, which will vary slightly, but generally speaking the following is pretty much the standard (In my opinion!) 1. PVA Dilution - 4 to 1 is the standard dilution, however I find a stickier, thicker solution helps with timing, so 3 to 1 is what I tend to use. If the existing surface is particularly porous, and you have the time, then applying a coat and allowing it to dry may be of benefit in the long run. Generally speaking, a good lathering, a short time to get tacky and then skim away is the best method. The wetter the Pva, the longer it will give you to apply your skimcoat, but if it is too wet you will get bubbling and shifting in your finish coat. 2. The two coat finish should be applied in one go. The first coat should be applied, then flattened to a reasonable standard. When tacky, apply a thinner coat over the first to smooth out any inconsistency. Then polish up with a wet polish and dry polish to follow. If timed correctly, everything falls into place very easily at this point. Furthermore, if done correctly there should be little or no sanding necessary before decoration spare the odd splatter in corners. 3. I know of some plasterers who say it is ok to skim over wallpaper. I however would strongly advise never to do so, and any plasterer worth his weight would agree with me I'm sure. It may be a hassle, but ultimately it's a no-no. Get rid of the paper before skimming. Finally, the only thing I can recommend is, find a good plasterer. If you aren't 100 percent confident of doing the job yourself, you will save money and be much happier with the result by doing so. If you are going to have a go yourself, then I wish you all the best and hope that my advice will help you along your way! All the best and Kind Regards Tom Williams

My advice to you is,leave it well alone as you obviously have not got a clue what you are doing.Plastering is an art that takes years of practice to perfect.Do yourself a favour,post your job on here,find a decent tradesman and throw the sandpaper in the bin.

firstly, remove all wall paper , remove all loose plaster and fill with carlite bonding [base coat] when all filled flat , 50/50 p.v.a. x2 coats then on the day of plastering another coat by roller or brush , it will require two coats of multi finnish plaster , first coat lay on evenly, when greasy to touch lay on the second coat , again when greasy to touch flatten trowel lines , remember if right handed work from the left and viser verser for left handed, finish the wall by using a good wide water brush and trowel flat adding water from the brush where required .clean floor and local areas with scraper and brush ,GOOD LUCK

best way for a smooth finish is employ a professional plasterer

Hi. after my plastering(skim) all my customer just paint the ceilings and walls, they don't need to sand, all the time and any plastering job I'm doing 2 coats of plastering. you can't skim on the paper, you need to strip of all the paper first, P.V.A. 1 part -water 3 parts. some times 2 coats P.V.A. is enough, some times 3 coats but this only the builder decide. you don't need to wait 24hrs for P.V.A.

Hi Tahira, As a rule you put a bonding plaster on the walls first then one coat of multi finish,each to there own I use pva at 50/50, you should not have to sand down the finish plaster it should be finished smooth,never plaster over paper for one it won't stick and the paper peel off when wet,the only thing I can recommend is that you get a plasterer to do the job for you. hope this is of some help to you.

hi i would put 1 coat of pva on at a 50 % pva 50% water as this will give you more time to apply plasterer. As for the second coat the 1st coat should still be able to trowl . Around 20 mins after 1st coat was applied you apply 2 nd coat . with thanks lee (lsb plasterers )

Hi Tahira you are correct in thinking 2 coats of plaster are required, there is a product called plaster prime which can be applied to a previously plastered surface, ideally remove and fill any loose or damaged areas first, leave for 24 hours then commence plastering. No need for PVA. You need to apply 1 coat of plaster and than recoat straight after the first coat, then you need to smooth it out starting at the same place each time, possibly up to 4 times depending on temperatures, no sanding required. Dont try and go over wall paper, it needs to be removed. hope this is a help, if you contact a plasterer in your area im sure they would be happy to help. Chris Furness Construction LTD

hi with regards to your question i would suggest you use neat pva on the first coat a day before and a 70 30 mix before you plaster when you plaster the wall you apply a coat then re apply a second coat when slightly tacky and then go through the steps of finishing if you can trowel the plaster up well enough you should not require sanding and filling, with regards to plastering the ceiling over wallpaper its not a good idea as the moisture from the plaster will soak through the wallpaper and it will all come off, if you do require some fine filling a good solution it gyproc easy fill as it sands back really well

I think your best bet would be to employ a plasterer, then you wont have to sand it down and worry about "pva and 2 coats". Paul

Sanding down the plaster etc etc is it worth it? If you are not 100% Confident in your abilitys then employ a plasterer. Danny
