kc brick layer

I have some studio apartments with the industrial look. they want to keep the old pitted concrete floors and just apply a clear sealer over them. I saw one of there models that was already done. it apears that its just a thick coat of clear polyurethane. Now heres my problems. I dont want anything runny thats going to go thru the cracks to the next floor. And the want to keep the old tile mastic and carpet glue on the floor but have it covered by the sealer. Would the solvents start reacting to the old mastic and glue? I need this coating to end up being at least 1/8 inch thick? any products out there that are water based and thick consistancy?

There are not any products that can do what you want. you need a clean sound substrate to apply any concrete sealer. polyurethane is not made for concrete. any clear urethane multi-component materials will be too aggressive to apply over old adhesives. gravity will get you when it comes to the material going through cracks - how wide are they that you think it will be a problem?

Let us know what you did after you complete the project - post some pics.

Keep the mastic?

To prevent problems on your part, why not ask them what was applied to the floors of the model and if they are satisfied with it. If so, how can you go wrong? To be sure, once you find out the product that was applied, contact the customer service department & ask if is made for this purpose.
The cracks can always be filled with backer cord followed by a concrete or motar caulk prior to application.

A lil bit of homework always saves money & problems later on.
