I have a new build (David Wilson) with a double garage.
We've had the house for 1.5 years now so the floor etc is all settled now.

The flooring in the garage is concrete, so not the best to keep the area clean. What is the recommendations to get the dust layer off and paint to seal?
 
It has got the usual gardening equipment on it, one fridge freezer and other light boxes.
The only heavy use that it might see from time to time is my car being parked there on very cold winter months.
For the most part, the car is kept on the driveway.
 
Thanks - didn't quite appreciate that you can just jetwash/hose pipe the floor to get the concrete dust off. Will do that this weekend in preparation (if the weather picks up again)
Frustratingly it has just hammered it down overnight.

Side question - We have found, especially in Winter, the garage is very damp ridden. Anything that was mdf (like shelving) was completely covered in mold by the end of the Winter.
Anything I can do to prevent soo much damp entering the garage?
Unfortunately the garage doors are no where near weather sealed and will be hard to seal off given the type of up and over door they are.

Most of the moisture issues are probably due to the single skin walls. Treating the outer walls with something like Storm Dry will reduce the amount of water coming through the external walls.

If any of your shelving is up against external walls, move it away from the wall by about 50mm, or if it is attached to the wall, put a layer of DPM between it and the wall otherwise it will just absorb the water from the bricks like a sponge.

The other issue is in British winters, a cold spell which cools down everything in the garage, followed by a mass of warm moist air coming in will result in the moisture condensing on all the cold surfaces. The only fix is insulation & heating, or dehumidification. Ventilation doesn’t work. Search for my thread in this forum on the subject.

Thanks for this - it is very interesting. 2 out of the three walls I can treat externally, unforunately the main wall of concern is only accessed from the neighbours side.

Do you know if this product is possible to apply on the internal skin of the walls?
 
Yeah good idea - the wall that I cannot access is actually for the show home, so that should be easier to convince the site manager to get access to paint.

Does anyone feel that this level of damp is something that DWH should rectify in terms of the 2year warranty?

If the builders are still on site you might even be able to get them to fork out for it.
I complained about the amount of water that was coming through the walls and pooling on the garage floor. They took the line that it is not supposed to be water tight and is only for storage of a vehicle. I had a motorbike in the garage and told them it was soaking wet and rusting. Only then did they sort it by putting some acco drains along the front of the door and they dropped off a tub of storm dry for me to apply to the walls.

Did the storm dry help significantly?

Yes. Before application the wall facing the prevailing wind would have water dripping down the inside during heavy rain. It was soaked through. After application it just doesn’t happen at all.

Excellent, thanks for the help - will keep you posted on how it progresses.
Last question - apply it with a brush or roller?
