[the power]

Hi i am struggling to get answers , as i need a quick one !!! can you help , i am currently coating my garage floor with International 275 hs which is a solvent based two pack epoxy .

i have plenty of extra paint left over after my first two coats and was wanting to add a third .

this is what i have done so far :

1st coat 4:1 ratio mix with 10% thinners

2nd coat is straight 4:1 mix- 24hrs after 1st coat

3rd ?????? can i add a 3rd 4:1 - 24hrs

Thanks Heap

I believe you can add as many coats as you want as long as you do not wait too long between. 8 hrs is often the window, some say 18 hrs, I do not know how they can give an accurate time because once it is down the floor is cooler than the air so I think the curing will be longer than the data sheet suggests which is calculated on a certain temperature range. It should be OK to do another at the same 24 hr interval, but don't wait any longer.
If you wait too long the epoxy cures too hard and you can get inter-coat adhesion problems where turning the tires of the car might split the two coats.
