gibby Posted July 22, 2019 Report Share Posted July 22, 2019 Evening all, Spent the weekend with a drum sander and am happy with the results but left with one annoying bit left. A narrow hallway where the boards have been laid perpendicular to the light coming in, annoying! The drum sander wouldn’t go width ways so had to go length ways to get the old stains out, but now left with scratched boards as I expected. Should I just use a hand belt sander to go with the grain widthways, or am I missing a trick? Also, any idea how to get carpet mastic/ glue off the edges with ease without gumming up the paper? Again, belt sander job or orbital? Appreciate the help. Gibby Quote Link to comment Share on other sites More sharing options...
Ultrastu Posted July 22, 2019 Report Share Posted July 22, 2019 Ramdom orbit sander is what u need This will remove most the scratches .but your gonna have to work hard .as going across the grain with a belt or drum sander will put really deep scratches in it and id never do that unless the floor was so cupped as to be almost beyond repair. You have made a lot of work for your self . Even the drum sander with the grain will require work to get the scratches out again a random orbit sander and work up through the grits from 80 up to 120 . Go down to 60 grit if you have to but dont use 40 its too scratchy. 80 .100. 120 . And 150 if you want a perfect finish . (If you using an oil ) 120 if a lacquer.

Ultrastu Posted July 22, 2019 Report Share Posted July 22, 2019 If the floor was previously finished with an oil or oil based varnish i hugely reccomend recoating with an oil and not a water based polyurethane lacquer. It will be very patchy when dry . If it was finished with a lacquer to start with .you may get away with a lacquer on top .but i wouldnt put oil over it .again it will look patchy .. The key is to get ALL the existing finish off . Its very hard work . Good luck . Quote Link to comment Share on other sites More sharing options...

I think he didn’t want to hear that 😂. It might be true but we both know how much work is involved now. 58 minutes ago, gibby said: Evening all, Spent the weekend with a drum sander and am happy with the results but left with one annoying bit left.

Buy some course grit and allow some time Quote Link to comment Share on other sites More sharing options...
gibby Posted July 22, 2019 Author Report Share Posted July 22, 2019 Thanks gents. Is it too late to say that I wasn’t in charge of the hallway? Gibby Quote Link to comment Share on other sites More sharing options...
figgy Posted July 22, 2019 Report Share Posted July 22, 2019 Use a sharp scraper to remove the old adhesive. As above the only way is going through the sanding stages to get the proper finish. Quote Link to comment Share on other sites More sharing options...
vampire Posted July 23, 2019 Report Share Posted July 23, 2019 I have a customer waiting for me to do this to her hall boards, not in a hurry to get there. Quote Link to comment Share on other sites More sharing options...
