Grippering on whatever this floor is called...

Builders seem to be using this crap screed more and more,Im not great with the names of screeds and i often mix up the names of them so a bit of educations needed if anybody can help out

I believe from a bit of research that this floors anhydrite? Besides nobody seemingly knowing what dusts sheets are anymore,It doesnt take a pin from gripper, it has stones in the mix and the top layer often cracks off like glass and goes everywhere. I did a plot last week with this floor and cleaned the edges,ran some spray adhesive around the edges and then gripfilled to get a good bond to the floor,left it for 2 days whilst fitting other plots and when i came to fit it gripper wasnt bonding that great and came up in places. I dont want to spend time and effort trying to do it properly sticking all the gripper in 5 inch pieces for it to come up anyway, and nor do i want to tap the carpet on and do a crap job,so today i just ended up leaving site as nothing was properly ready anyway.

Whats the best way to deal with this floor, i recommended it needed latexing as it was very uneven too.

 

i know a doorbars not the straightest thing around,was all i had to hand for a quick photo. Ridges would definitely have been felt underfoot though

 

Any you can reccomend?

 

If it's anhydrite you will need to abrade the surface area where you are going to stick the gripper down to remove the latent top level then vacuum before sticking the gripper to it. Otherwise anything you stick to it will come away with the weak top layer.
If you want a fast strong adhesive for your grippers use Flexyfix. Apply it with a 3mm bead and each tube will do 40 linear meters.

 

use flexyfix alot when we need a fast fix, but if prepping days ahead we always use gripfil as its stronger than anything else i find. Cant see flexy fix going 40 linear metres and holding a power stretch with a 3mm bead, i maybe get 15 linear metres from a tube at best

 

Grip fill will blow off anhydrate. Vacuum and roll acrylic primer around the edge and then use f33 or flexifix and it should grab

Haven't nailed into solid floors for decades. It was outlawed by John Lewis stores after a flood over a weekend in a block of flats costing quarter of a million pounds (not by me). We buy gripperrods gripper with no pins in. Cut them into three pieces, no need for any smaller.

Stixall is PU adhesive and excellent though not as quick at drying than some others ( takes about 2 hours to set.) Not sure about priming anhydrite though. We usually use spray and then hot melt gun. We also use it to seal gaps in between floor and skirting.

 

Stixall that is.

 

You cut 5ft sticks into 3 bits and stick them? Must have floors as smooth as glass and stretch it on with a strong glare...

 

Never had a problem unless floor is sandy. I apply 4 large beads of hot melt from a quality gun to the high points and gently slide in. It actually straightens the perimeter edge. May not work with wet adhesive though. I always prime with lots of spray adhesive. Carpets can be fitted immediately.

 

Only had to use a power stretcher twice in 40 years.

 

Does that take a power stretch? Ive looked at the hot melts and i do wonder if the glues strong enough as ive read people say theyre crap . I used to use one as an apprentice but never since

 

Yeah i know fitters who have been going for 40 years and havnt got a clue how to fit properly so experience and time in the trade doesnt say alot to me anymore.

I respect work when i see it and master fitters etc but time in the trade doesnt cut it for me.

Must fit alot of small rooms to only need a power stretch twice in 40 years,i guess you could have staynailed it back in the day but then id count that as a time youd need the power stretcher too.

Not to say you're in that category,but there are far too many in it.

 

I agree with you. Yet at the same time I find that young fitters haven't any experience with patterned carpets. They don't know how to line patterns up and match on stairs etc. Most have been trained for not enough time, and the drop in rates in recent decades has produced an expectancy to rush the work.

I have a shop now and cant find carpet fitters to the standard I expect. I only fit a couple of days a week. Was with the major department stores for decades where they used to train up apprentices. These guys have mostly retired now though.

By the way, what do you do with your power stretcher when there are big radiators present low down near the carpet surface?

 

It’s hard to gain experience fitting patterned carpets when no one buys them anymore. Unless your lucky enough to fit for a shop with a decent Axminster or brintons account

I was just about to say the same, havn't done commercial for a while but the last one I did was at a new college extension in Peterborough and they had the gel back swirly stuff and that blew my head off, pattern match was a nightmare. 3 pieces of 7meter cuts we had to use our kickers to stretch it out either end to get the match all the way, done me nut in. Its like the piece you were trying to match with shrunk
