I have a cheap method of dpm'ing your subfloor. When i used to work Egypt teh lads had a secret mix that works as a surface DPM. This is no joke. If you feed a camel grapes its urine is actually water proof when dried. I didnt believe them but sure enough they proved it to me. Do...

Are you pulling my plonker here? Primer G is a PRIMER. It is used on anhydrate to seal the anhydrate before you apply cementous based adhesives / compounds etc. It is a PRIMER, NOT a dpm system.

if your subfloor has a working dpm under in then you can use a 1 coat surface dpm. This will need 1 hour to set. Then you could use a rapid set compound that would be walkable after 2-3 hours. So in total including labour time the hall way will be out of action for around 6 hours. As for...

someone that knows there stuff wont need to take core samples or damage your subfloor. If you was doing yourself or using someone that didnt know when looking they would send off a core sample to someone like ourselves. Cant say for sure but Nick Hood and Chris may be able to do without...

in case i have confused you, Mapei dont warranty there epoxy products over subfloors with rising damp. Only residual building moisture. I just through another name in that 'we' use for epoxy products. O and mapei are the largest manufacturer in the world for DPM, Adhesives, smoothing compounds.

On a concrete subfloor you should use a smoothing compound ideally. If installing a solid you should first put down a surface DPM and then you can use most smoothing compounds out there providing its strength is above 25nm. Also make sure your subfloor has a working DPM under it by...

Us 'trade' professionals all use Fball, Ardex, Mapei products. IF there was a cheaper product out there that can do the job then WE (the trade professionals ) would be using it. The End !

Smoothing compound at what compression strength? basically a compound that is not suitable for any thing other than a floating floor like sheet domestic vinyl. Also i dont know of any compounds that the manufacturer will warranty over it. It can be used under a course flooring screed over 75mm...

In your pics the subfloor looks weak. You can get it tested by sending away core samples but not cheap unless you know someone that knows what there looking at and an tell you on site with some simple tests. There are very few people that can inspect and give you a verdict on strength tho...

that dpm you would use under a concrete floor. So for example where you have taken out a wall and there is a void between the two floors maybe 6" plus deep. Also you may use it when tanking a area. You can not use a smoothing compound over the top.

as daz says. However you need someone to assess the surrounding area as this will make a difference on if it will work. DAZ, have a look at picture 1 + 2 that he has posted up. Hard to say of pictures but do you think there may be bonding issues? also he has removed magnesite from the...

Stanley james flooring (chris) in sheldon. He can do the floor prep but wont do the wood and you also have Hoods carpets (nick) just up the road from you. Again wont do the wood. Both of these fitters i would rate as being in the top 20 in the U.k. Both have been in the floorlayer of the...

Hi, you will still need to overboard with plywood but you only require a 4-6mm plywood. You then apply the compound to this. You wont have moisture issues as the compounds chemical cure and also the plywood protects the floorboards while its curing. The Fibre reinforced compounds are...

yes you can but that wont help. You need to use a firbe bonded smoothing compound. This posy may help - http://theflooringforum.com/showthread.php?5493-1-half-is-concrete-and-the-other-is-floor-boards It is actually referring to wood floor meeting a concrete floor but same prep anyway.

what plywood you need will depend on how good the subfloor is. For gluedown you can normally get away with 6mm. for nail down going the same direction as the floorboards you are really looking at 18mm + for security. You may not find any thing for 'slip tongue'. It is a method of...

You do realize that doing such act's leaves the returned item 'used' so this means the item cant be used again. Its sold for cheap to market traders etc. The knock on effect is we all now pay more for goods as Argos etc has to cover the costs of people doing as you suggest. We wonder...

Ye, agree. Isnt that flex fine for a 10KW shower? :shock: Reading a few posts on here, it wouldn't surprise me how many people actually try the above! Not that i know (other than reading on here), im not a sparky and far form it. PS, love the RF pic of the month. Been following...

bamboo is a lot more stable than other products. However it tends to move around in the first few months of install and then it stays pretty stable. (rh depending) As you have a engineered bamboo product it is even more stable. Your issue is wanting to nail the same direction as...

rf, can you take the actual plug temp also please. Can you get the temp of the pins? Many thanks for doing this mate, when i asked about flex and plug temp i never realized it would progress into actual testing.

How do you work out emissivity?
