How to paint concrete floor - Building Materials

if you want to seal the surface a epoxy paint is good !

but if the water come from under the concrete slab only a hole with aggregates ( small rocks ) and a swamp pump works fine !

you did not provide info on the type of the paint and what surface it will be used on - there is difference between the floor, desk, wall and car body... all are flat surface but adhesion and work of the paint differs.

depending on the pre-existing paint, but you need always to "key-in" using 120 grit paper or 150 grit screen.

if paints are of same type, then paint in - if these are two different paints, you need to strip or isolate old paint, and then use new paint.

You can, but it will not adhere well, and will not stand up to wear. Latex is designed for walls and does OK on some types of furniture (depends on material and finish), but not for floors. If it will be in a low traffic area, and you really want to try it, then clean the surface well, let it dry well, and do a small test patch, then give it a few weeks, but I would not count on it being durable under even moderate traffic, especially if the traffic is with something other than smooth soled shoes. Nice idea, though!

take up the floor. lay new underlayment ( I recommend concrete wall board at lumber yard), then add top surface (ceramic, linoleum, wood)
good luck

1 Make sure that the surface of the concrete is cleaned thoroughly. Remove stubborn dirt or stains with a mixture of one part degreasing cleanser and two parts water. Rinse the concrete well and wait 48 hours before continuing.

2 Use a large paintbrush or a long-handled paint roller fitted with a fine-nap roll to coat the entire concrete surface in a thick layer of soy-based or other environmentally-safe chemical stripper. Allow the stripper to eat away at the sealant for 10 minutes, scrape up the peeling sealant with a paint scraper or putty knife. Clean up all of the debris.

3 Rinse concrete to remove all of the stripper. Let the concrete dry 48 hours. Apply the new sealant or the finish of your choice .

did you ever try to mix water with oil? what was the result? are you sure that you can cross the street without adult holding your hand?

unfortunately you need to remove all that paint, just drop few shovels of fine sand over, and scrape it... sand will adhere to the tp surface of the pain and will allow you to scrape it. after you scrape it off, use any degreaser or similar product to wash reminder off, leave it for few weeks to dry through and then in small patch try if it would accept latex pain, roll it very, very thinly and leave overnight, if it is dry (solid dry) after 24hrs and do not peel off, you can then use this paint on the rest of your garage floor.

now, i would advice strongly against painting garage floor with any paint except concrete paint (they are usually water based with strongly alcalic ph), and after that use concrete seal. this should give you long lasting surface, sealed from oils, dust, water and whatever contaminant you can imagine in the garage.

You have to start outside.
First regrade slope of soil away from foundation. Add a drain and tile to direct water away from house.
If necessary dig down along foundation wall and add membrane.
In the basement, add a sump pump to pump out water to keep moisture out.
Clean basement wall, and add some waterproofing paint.

It seems possible that moisture may be building up under the hood of your car and forming around the coils and plug wires. You might try leaving the hood up when parked in the garage for a couple of days to see if this helps fix the problem. If this helps go to your parts store and buy a can of spray ignition sealer and spray on top and bottoms of plug wires and boots, then the tops only of your ignition coils. do this only when the engine is cold and not running Let the spray dry completely before starting your car. If you still have a moisture problem coming from your garage floor you might want to have your vehicle undercoated to stop it from rotting out your frame and floorboards as well. Or another idea might be to paint the floor with a concrete sealer available at your local paint or hardware store.

Im guessing but if you have marked the floor you can remove them using a floor screeder with a very fine abrasive head pour a small amount of liquid soap on marks first then simply sceed them off
