instalay and karndean

Who told you to do that?

 

I don't like the idea of Instalay but if your asked to use it why did you not leave an expansion gap ? It requires an expansion gap so you didn't give your self the best chance really ? I'm defo not guna try it with out a sample roll to test

 

All ready asked & it was a big fat no ? So I'm not buying any & defo not risking it on a job !

 

Its a PS adhesive. Everyone tests adhesive in the wrong way and with what you have said you have also made the mistake.

We all (including myself before it was explained to me) for some reason decide to test adhesive strength by pulling apart what ever it is that is bonded. PS adhesive has a very poor 'pull apart strength' . I say pull apart, i mean pulling upwards from the floor. (as our floors are stuck to the floor after all. )

Have a think about this (how it was explained to me), which way are floor-coverings trying to move? They try and move sideways ! NOT UPWARDS unless they have hit a wall and failing through compresttion of hitting the wall and then they go up. (the floor is already failing at this point)

So if we was to test a floor by pulling up we are testing the strength wrong, we dont care how strong the adhesive is pulling upwards. What we want is sideways strength, try testing the product by pulling it sideways, you might find that its very strong.

 

I have a some for testing

I did install some at harrogate show and there was no issues. Also been using for woodflooring for many years without issues. However i would like to do some point loading tests on it and temperature changing tests so im installing stuff at front of training centre that will be subject to direct sunlight and also pallets/forklift trucks driving over it.

Will let you all know the out come.

 

Good give it hell !

 

Thanks but no thanks !
