hi can someone help. At the moment we use a dualgrip gripper but i understand you can get a gripper for concrete and wooden floors. Why is there different ones if the dualgrip works on both? sorry if a stupid question. I have only been working for 3 months and still in training.
personally I don't like using dual purpose gripper on wooden floors as the pins don't anchor into the sub floor aswell as the ring shanks that are used with wooden grippers, also not very good on stair risers. For a superior fixing - wooden grippers on wooden floors! I prefer to use dual purpose on concrete floors as the rings on the masonery nail hold better.
dual grip is as it says. However it does not hold in either subfloor as good as the correct gripper designed for that subfloor. Wood gripper can only be used in a wooden subfloor but holds alot better than dual grip. Concrete gripper holds better than dual grip in concrete floors but wont hold in wooden subfloors.
gripper posted the same time as me! however it seems gripper prefers dual grip on concrete over concrete gripper. Guess thats personal choice then. Saying that i always glue the gripper on concrete as well as pin it.
yeah it is a bit of a personel prefernce, sometimes a concrete floor can be really hard then I will use crete gripper. I think dual purpose is a bit of a cop out, that makes people lazy...but it can be used in certain situations to your benefit also on a bitumen floor you could use wood or dual purpose, depending on how hard it is. I like to keep a box of all 3 on the van
to add to "grippers" reply about bitumin/ashfelt etc. Be carefull pinning these subfloors. Sometimes these subfloors are made of the above to act as a surface dpm membrane. If it is acting as a dpm you MUST glue the gripper as if you was to nail into them you can damage the dpm causing moister issues. Moister issues should not be a problem with carpet but in the future if the carpet was to be changed for wood/ karndean etc you would need to repair the dpm.
Hi i agree with the other lads ,and with Matt about the asphalt or bitumen floors with the sticking of the gripper, hope that helps
it seems to be the shops that have the prefrence for the dual purpose, most fitters prefer to use the wood or crete gripper pins ..
dual purpose are of no use what so ever for any type of floor! reason being is that you use wood on wood floor and on concrete you pull the nails out and glue the gripper to the floor using rapid settin gripper adhesive ( only use this if you are planning not to put a great deal of tension in the carpet ie; small hall or tiny room ) or grip fill is the correct way to install onto concrete floors and stair cases ! or if you have time drill and plug them but thats not really the greates one to make any money as you will be there all week lol
