I have an indian stone patio, sandstone is not usually attacked by brick acid, but cement and limestone do get attacked. So start with an inconspicuous bit to get used to using it. Brick acid is hydrochloric acid at a medium strength, varies by supplier, you can usually buy it at almost any of...

It is where the mortar is not fully bonded to the sandstone, it has slumped/shrunk or been shaken away from contact with the underside of the stone, so moisture is getting in. If they had used 5 dabs it would be circular marks, possibly laid a little wet. Most likely will stay like that now.

Other timbers you could use outdoors are "greenheart" and "Purple Jarrah", but you would need carbide tools to cut or trim them.

Make sure the trough has holes in th bottom, natural habitat for tulips originated in dry hot deserts, they used to have the bulb about 50cm down to avoid the worst of the heat and spend all the rest of the year bone dry.

Hi, Had a roof done a while ago. I worked out that the "flashings" on the ceramiic tiles have caused a crack in two of them some time after laying. I used some spray on stuff to buy some time, but it was rubbish and has gone hard. I am thinking about solar panels on the roof sometime, so that...

All very well setting up the wedge gap where you want it to go, but you also have to consider where the center of mass of the whole tree above the cut is. If it is significantly off to one side, that is where it is going to fall. You may need to cutoff some of the higher up smaller branches...

It is just Hydrochloric acid, jam jar and a stiff brush to apply, then hose off afterwards. Keep it away from the cement/grout between the bricks etc, it does etch that as well.

Brick acid applied to the sandstone slurry splash with an old toothbrush. Hose the acid awaywhen you are done, or stopping for a break. Use some household gloves to stop any splahes making your hands sore while you work ( I personally dont bother with the gloves because I am comfortable with a...

I have two old pine large beams to try and dispose of, both about 6.5 metres long and nominal 4" x 12". Any Idea how much I should ask for them?

Also, the wider and thinner a vent hole is the less air will actually go through it. The static "boundary effect" reduces the effective gap.

Clear silicone inbetween the work surface and block, would prevent liquid runing down, would only require a one-off heaving of the block. Then the paintbrush idea has less to sweep out. On another furum one person had a chip that broke on his black granite worktop, clear epoxy recreated the...

Also there are two different types of twin slot that are almost interchangeable, could be an imperial/metric switch? I had to extend the number of rails from the previous house when I moved and the new brackets rails needed a bit of filling to make them interchangeable. If you buy them all in...

make the bits in green quite chunky, they can be fixed on the 1200mm centes, and the bench fixed for the 1500mm. It will need each green timber in your picture to have two screws at each fixing to the wall.

I used twin slot shelves in the garage, needed to use battens on the wall with loads of screws to keep that firm, then loaded up with lots of stuff way over the limits and has stayed up for 20 odd years now. I did find that an uneven wall can cause the rails to bend (front to back) when screwed...

for a given timber size used for a shelf the sag is proportional to the cube of the distance between supports, so going from 1 metre to 1.3 metre spacing gives (1.3)cubed extra sag. So would give more than twice the sag. Mr Rustys answer would help you use a thinner shelf without the sag. Even...

yes, it is next to the edge of the garden, and is a usually dry spot, the blocks set in the ground are out of the way and have been there over 20 years. It is usually dry in that part of the garden, so not expecting it to rot quickly.

The hollow blocks are in the garden below ground, and I need to add something so that a bed can be flat. We have very sandy soil, so often very dry, it does not usually rot fast in that part of the garden.

Hi, The blocks are 215x440 reasnoably flat, and I have some spare 100mm square posts that I need to fiz horizontally to the top, but I have the hollows vertical, so run the risk of the holes bursting if I drive a screw down into them. Has anyone tried something like this and got a simple answer...

I had a damp part of the garden and tried wooden stepping "stones", bought some second hand purple Jarrah and some greenheart. The geenheart managed about 12 years and the Purple Jarrah has managed about 20 years. They were not cheap, and needed a carbide blade to cut, but it was only a few...

are they two bit from different makes of piping, they do not always interfit very well, make sure it is all made by one company, look closely at the molded in part numbers and logos to be sure.
