Does it spray thick latex paint without thinning?

Airless sprayers at this pressure generally handle standard latex and primer unthinned. Very thick or old paint may still need a small amount of water and a larger tip.

What tip size should I use?

Match the tip to the coating: a smaller orifice for stains and sealers, a larger one for thick exterior latex. Check the tip's maximum pressure rating against the sprayer before use.

How hard is it to clean?

It takes time. Flush with water or solvent immediately after each job, clean the filter and tip, and store the unit with protective fluid to avoid clogs and seal damage.

Can I use it for exterior siding and fences?

Yes, that is where it saves the most time. Mask windows, trim and nearby surfaces first, since airless overspray drifts further than roller spatter.

Does it come with a hose and spray gun?

Confirm the included accessories before buying, since bundles vary. You will typically need an airless hose, gun, tip guard and a tip matched to your paint.

Is it worth it over a roller for one room?

For a single small room, a roller is simpler and cheaper. The sprayer pays off on multiple rooms, ceilings, fences or siding where speed and finish matter.
