Floor variations

[DavieA]

Quick post, Just wondering whats the best method for determining how off a floor is interms of flat and dips/humps before applying Slc and are screws the best way to mark rquired height?



Never used Slc before and want to do it right.

anyone used a Water level for this ....?

use a long straight edge, run it along the floor and you will see the dips in the floor, mark them with a pencil, and you know these are the areas that require leveling, you can use screws or packers to help you, but i tend to do it by eye.

Screws are ok, make sure no pipes in the floor though. Water levels really ned 2 people. Laser level needs just one but a straight edge and a level is my way mostly.

 

[DavieA]

what do you use as a straight edge and whats its length?
Was to get an 1800mm level but could just use a straight edge and my 1200 level ontop if required. I Think its a water level in this video and looks like other end has been setup next to wall allowing one man to operate it but i could be wrong, what do you think?

Yes water levels can be used and great if yo need to go around corners etc. A laser is easier to set though.
oh and I posted about thes pins over a week ago

I either use screws or even bits of ply or plastic sheet about an inch square dabbed on with silicon to the required thickness. Don't go wasting money on any specialist gear for doing nothing but giving you a guide for a depth of slc.

Yeah sir ramic your post is whats set me thinking, haha. When your on about a laser level do you mean set it up at a desired height and measure using a tape from floor to where the laser hits the tape? Done that before but took ages and water level look quick in your previous post SLC Advice and if one ends setup at your required height, syringe marked say with tape and water coloured youll be able to see it at a distance or am i just trying to convince myself??

 

[Gazzer]

Nope laser lot quicker. Just set laser at about 600mm height then use a ruler

ok, is it as accurate over 10+m? not sure my stanley laser will beam that far:lol:
