    Plasterboard adhesive not set after 2 weeks, clay like consistency

    It is in date so I don't think that is the issue, I have been having a closer look at a lump of it that I have taken off, I am starting to think that maybe it wasn't mixed properly. It is really crumbly and wet, maybe that in combination with the coldness of the doorframe area have caused it. I...

    Plasterboard adhesive not set after 2 weeks, clay like consistency

    I have fitted some plasterboard a couple of weeks back using plasterboard adhesive. All seem to be ok but I have come to do some more today and on inspecting the bits nearest the doorframe it is really damp and the consistency of clay. I can just pull it all off by hand, the stuff further back...

    Setting out a garden fence at right angle from house

    So do the initial triangle setup and put a stake in the ground, then string line from the house to the end of the garden making sure the string is touching the stake?

    Setting out a garden fence at right angle from house

    Hi Bernard, thanks for the suggestion. My issue with this method though is how to carry on the measurement to the bottom of the garden. A string line is stretchy so my measurements are inaccurate. Could I just do this with regular string / twine instead? Or is there a recommended way to extend...

    Setting out a garden fence at right angle from house

    I am attempting to put a fence up along a rather large (150ft) garden. The actual fencing process itself I am ok with having completed fencing at the front of the property successfully. My question is one of setting out. I need to fence to be at a right angle from the house and to extend in a...

    Sister joists with plywood instead of C16

    In fact, just turned the spirit level round the other way and the first one is accurate. So looks like faulty spirit levels are a thing after all

    Sister joists with plywood instead of C16

    I am having a bit of a strange one with this. I worked out the highest point and started from that joist. I used a spirit level and fitted the length of 47x125 to the joist with poly glue and turbo coach screws. I then moved on to the next joist and did the same thing. I then went back with the...

    Sister joists with plywood instead of C16

    Point taken, I can also foresee issues with screwing into the chipboard and it crumbling. Think I am going to go for 47x125 carcassing timber. It is smaller than the original joists but as I am not repairing it then it seems like a good trade off between price and size.

    Sister joists with plywood instead of C16

    Thanks for confirming, always nervous about weight for some reason :) As I am not repairing the joists but merely slightly levelling them, could I just use chipboard 18mm flooring glued either side of the joist? I have lots of pieces already so would be a cheaper option for me.

    Sister joists with plywood instead of C16

    I am about to put a chipboard new floor down in a bathroom and want to level the existing joists as they slope towards the party wall. It is only a very small span (1m) that needs levelling as the floor that sits underneath the bath has not been removed. I have looked at sistering the joists...

    Use expanding foam to close cavity round window

    Thanks, just wanted to make sure before I caused myself more problems than I am trying to solve :) The debris is snots of mortar which are attatched so I can't remove them. What sort of insulation would you expect to find in there? I don't have any insulation on any of the walls which I...

    Use expanding foam to close cavity round window

    I am replacing plasterboard round a UPVC window. I have already added expanding foam round the window frame to close up any gaps. But I also want to close up the cavity round the window, am I safe to use a small amount of expanding foam for this?

    35x80 Ceiling Joists - Equivalent size?

    I am about to embark on a loft hatch enlarging project, I am trying to find some appropriately sized timber so I can sister some joists. My current joists measure 35x80mm, I can't seem to find a direct replacements. Is this an older joist size that is no longer used?

    Void filled with bricks underneath front garden?

    Not sure if this is the right place for this, building might be more appropriate... I am attempting to install a fence post in my front garden against a retaining wall. I have dug gown about half a metre and have uncovered a void filled with bricks. Is this normal? I am assuming it is where...
