I am looking for info on runing LED lighting for a small workshop from a combination of batteries and solar with mains charging power as a backup when the battery voltage is low and/or sunlight is limitted. Ideally I'd like to run the lighting on a low voltage (12v ???) circuit. Obviously it's...

I have a garage with wall and footings constructed as in the picture. (Not sure the embedded image is displaying so I've included a link to the jpg.) https://1drv.ms/i/s!AiSdxKZH7MXJgSeRBs-p7tS77CTH There is a significant amount of thermal bridging through the single course of concrete...

Thanks. If a smoothing compound is likely to be necessary, is it not easier to just use a self leveling compound to start with and forget about grinding? By "what volume of dust", I meant how much will accumulate in the vac, and how do you dispose of that? (Presumably the hire companies don't...

I've got an uneven concrete floor about 40m^2 that needs to be smoothed and coated with either eppoxy/resin screed/paint. A lot (but not all) of the floor has bumps and ridges of up to about 5mm resulting from a coarse aggregate and tamping. About half of the floor has some sort of paint on...

I can only see walk-behind machines on their website. Have you used something handheld of theirs?

Does anyone know a company in within reach of Herts that hires handheld trenching tools like these?

Need to raise a sloping section of concrete floor (area = 3m x 5m with 50mm drop over 5m) so it's level with another section of floor. Is screed the best way to do this and if so, what are the considerations with screed adhering to an existing concrete floor?

Are insulated screeds suitable for a garage floor if they are used over an existing concrete slab?

We have a large garage that is going to be demolished and rebuilt. In the mean time the roof is leaking and this needs to be dealt with to protect the contents. The roof is part felted (flat) and part corrugated (with a shallow pitch). I've masticed cracks in the flashing with the adjacent...

We've recently moved house. The survey highlighted a couple of cracks running down from window frames, but said that there was no concern over ongoing movement. We just need to repair them. Interior is fine, I can cope with that. Exterior, there there's a crack through the mortar for 6 or 8...

I'm planning on digging a pond with one or two "courses" of railway sleepers around the edge, and there may be some soil back filled against them. The sleepers are probably going to be new (not reclaimed). I'm not decided on hardwood or softwood. I don't mind them weathering significantly over...

Exterior door damaged by rain getting into the wood. The wood is now dry, but there's a small area that remains persistently slimy, even though it is hard. I certainly can't push a thumbnail into it.) Any ideas what can be done about this slimyness as I obviously can't paint the door till...

I've found 3 exterior paints that claim to be high build textured exterior paints that can be applied with a roller. Are these likely to be better than Sandtex, or anywhere near as good as the paints that need troweling? (We are going to struggle to justify the cost of getting someone else to do...

I have some patchy render that has obviously been repaired in patches. After a couple of coats of masonry paint (I already had a part used can) the patches are still quite obvious. Is textured paint (eg Sandtex) likely to help?

Was planning on replacing rotten timber and using filler, but still slightly disappointed with the hardener. Oh well. Research twice - but once.

I'm trying to treat several window frames with Tetrion Wood Hardener. Despite what it says in the instructions, even after several treatments the soft wood still isn't particularly hard. Am I expecting too much or are there better products?

I know the usual way to lay a brick driveway is to lay the bricks on sand. We have a very large ant colony in the sand below our brick drive and have been recommended by peat control (who have no vested interest) that our best option is to relay the drive without the sand. We would like to...
