MikeSharp01 Posted October 30, 2017 Share Posted October 30, 2017 (edited) Just about ready to scrim / skim the drywalls in the garden room. Just need a steer on the best mud (plaster / filler) and perhaps a bit on coverage so I don't over order or miss out on potential price breaks. Do I buy ready mixed or powdered? I will also invest in a ROTAX for sanding / finishing as I don't yet have a large (ish) orbital sander. Any and all contributions accepted.

ProDave Posted October 30, 2017 Share Posted October 30, 2017 Are you taping and filling, or plastering? Completely different answers depending what you are doing. Link to comment Share on other sites More sharing options...

nod Posted October 30, 2017 Share Posted October 30, 2017 Hi Mike You are better using one coat of joint filler Normally stays workable for about 60 minutes Use sparingly as it is quite hard to sand back Just enough to cover the finer tape or paper tape Try about 5 kg Mix a small amount at a time normally about £10 per bag Give any high spots a quit sand Then your ready for two coats of joint cement coat everything including screw holes you can mix as much as you want as it is an air dry product just cover the bucket over night let it dry white and a gently sand Then you can apply the final coat 22 kg bag is around £25 you can get ready mix in a tub But it’s more expensive and can be a bit sloppy Hope this helps Link to comment Share on other sites More sharing options...

Russell griffiths Posted October 30, 2017 Share Posted October 30, 2017 What I would add is go and buy some quality filler knives/trowels/spreaders whatever you want to call them, don't be trying to do this job with your old glue covered paint scraper. Also try to get a good finish of the knife, don't rely on sanding, get it 90%first. 4 trowels 3" 6" 12" and a 3" with an angle for corner work. If you want to buy a really expensive giraffe sander I will buy it of you afterwards as I intend to tape and join our whole house. Link to comment Share on other sites More sharing options...

Yes I have a plan but I don't need a giraffe sander right now as the garden room is quite low but in the main house I will - you can spend of a grand on a good Festool! We may end up needing it at the same time! Link to comment Share on other sites More sharing options...

For a one off house I wouldn’t bother purchasing a graphite sander ive used a pole sander for years if you keep the jointing neat and sand between coats You should be able to sand down and average size house in a day and then seal with a top coat in half a day Link to comment Share on other sites More sharing options...

Other wise it sounds like a plan. Link to comment Share on other sites More sharing options...
nod Posted October 31, 2017 Share Posted October 31, 2017 No gypsum do a top coat primer which seals the boards and helps the paint cover evenly It goes on really quickly You don’t need to keep it even like paint as it soaks into the board and joint Link to comment Share on other sites More sharing options...
MikeSharp01 Posted October 31, 2017 Author Share Posted October 31, 2017 Thanks @nod I was going to do a course on this but think I will have a go at one wall and see how I get on as it looks like a job I should be able to do and it is another chance to buy some tools!

Yes just take your time its worth sponging the outer edge of each joint saves a lot of sanding Link to comment Share on other sites More sharing options...
