solway i have so many questions where are yee ??
on a health and saftey note can i brush the walls wearing my "jedi dressing gown" ??
No no so called plasterers,I see 2 rakes and a harvester. I said BRUSH,sound it out now....BBBBRRUUSSH... YES WELL DONE, BRUSH. Does the one stop shop sell floats with 3 or 4 nails hammered into the top of them....? I think not. Classy bit of a tool that....not. I don't buy a float to hammer nails into the thing,but yes I'm always on the look out for a nice brush for keying up walls for skimming. Great piece of mind knowing that my skim is 100% tied to the background where as ye girl's have skim on area's where skim is resting (just resting) on shiny non keyed backgrounds. Granted most areas(if ye have 6/7 nails in the float)will be keyed but there are area's which won't be. Better system and method all round by far. By the way why don't ye start making floats with nails in them lads and "copyright the idea". The question asked at the start of this thread was "Is this key good enough". Well I know my key is good enough....Guaranteed!!!. As for ye're way,I wouldn't guarantee it. Monkey see monkey do systems is what you and your mates are used to flynnyman,algeeman etc. Try it the next time guys/girl's,go on go on go on go on go on go on Go On!!!! I'm outta here,iv to buy a float in the morning and make s**t of it straight away by slapping a fist full of nails in it. Total waste of 35 quid.
Use screws then you can screw them further out to use on your scratch coat for rendering then unscrew and use for keying ready for skimming, then unscrew completely to use for rubbing up smooth, hey presto you've got three tools in one, then use your brush for sweeping up skim that's failed from the last bloke xx night night

fuuck this im going to bed.
Jesus Christ,your float must look like something out of a driving range with all the holes in it and you use it to float external walls......WTF. Rough as a bears arse I say, ROUGH. I suppose your skimming trowel is used to lay on sand+cement and spatter dash aswell and the labourer also uses it to scrape up your failed skim from the floor. Classy outfit.
Classic [emoji23][emoji23][emoji23]doubt you'll get much of a key with that brush but loving the idea. See flynnyman,if you weren't so narrow minded you could have copyrighted that idea and retire on this invention. Simple and effective. Flynnyman is simple and the idea/invention is effective.
I musst give you a call lastlaff,tweak the invention a bit and we're on a winner,a dead cert of a F*****g' winner. [emoji106][emoji106][emoji106]

I would say you are using the wrong tool for key there mate' a devil float is what ya want figure of 8 all across'when applying multi finish on to s&c a devel float ' the tool you used for key is more used when 2 coat render is applied , sound like you didnt prepare the back ground ''its alive parasites have got behind and pushed it from the wall' hope that helps.....

Where are you buying your floats at that price
a plastic float with between 4-6 coper nails pushed through the end 'is the way I was shown or use a comb , but prefer the float, if i seen a person -plasterer -person using a brush on my site would be instantly dismissed, all areas of the wall are keyed lol

Your bloody car/van would be "keyed " with that attitude the float does its job as described "consolidating " the surface plus the nails or protruding screws adding a key I'm sorry but brushing alone on sand cement is not good enough! For a key yes but not for consolidating the mor tar together. Makes me laugh. Traditional methods tried and tested for years but modern stuff it's still a learning curve

Hi my two pence worth. Information given 2 coats of S & C with skim coat. First coat over mesh with waterproofer added. This is the red flag to me. To much waterproofer causes S and C to go powdery. Can you scratch the first coat with your fingernail if you can you've got problems. S and C coats do need a good mechanical key. They have scratched first coat with a Refina EWI (External Wall Insulation) combe used for scratching the adhesive after you trowel through the mesh. s**t key basically should have used a scratcher. If they have used two coats of S and C which I don't think they have from the pictures. The top or outer coats need to be the same strength or weaker than the proceeding coats as during chemical curing (Setting) a stronger coat on a weaker coat can pull away (blow). I would never use a stronger mix than 5 to 1 with modern Portland Cements they are very strong. Adding lime will not make S and C coats blow. All Portland Cements are made from Limestone yes Lime. From the picture you supplied looks like second coat, ruled and floated coat is a light weight plaster, Hardwall or Carlite Bonding Coat. Carlite Bonding will bond to smooth concrete, I personally would bluegrit (Betterbond) smooth concrete first. If the first coat (scratch coat, although this one isn't scratched) is hard, not easily scratche'd with you fingernail OR powdery (if it's hard it will just file you fingernail away) then I would blue grit it and use carlite bonding, it will form a good BOND with smooth surfaces then skim same day. If the scratch coat has gone soft with .the waterproofer you maybe able to save it. Buy a gallon of SBR painting that onto first coat. Never tried it myself but I have heard it can help harden it up (note to guys can't be used instead of Viagra). Good luck and sorry for length of reply

waterproofer in floating coat seems to be problem here ( i personally think it should never be used inside) to much waterproofer means wall have no suction when the scim coat is applied the first coat laid on never really drys the finished wall drys from the outside in a chemical reaction can cause a film to be formed between the s&c and the scim- everything looks fine for weeks or months untill the inner coat drys out then the 2 coats part company- how to check if a wall has to much water proofer in it just sprinkle with a brush if the water runs right to the floor u re in trouble this also causes immense problems for painters in winter time with paint not drying and staining on certain parts of walls --by the way scratching is a tro back to the old lime mortar walls has very little to do about wether scim sticks to sand and cement or not --scim a plain floated wall 3mm go back in 3or4 days with ure bolster an see how hard or easy it is to shift { remember first and formost waterprofer is a repellant }
