Coming from Marcos Hway (Assuming you're coming from Aurora/Cubao/Katipunan area)

Go straight towards Antipolo via Marcos Hway.

You'll pass through Sta. Lucia East Grand Mall and Robinson's Metro East on your right. You'll see a blocked intersection (Marcos cor Imelda/F.Felix Ave). Go straight a little till you see the U.Turn slot.

Take that U-turn and merge right (you'll pass McDonalds on your right and take a right at the junction (you'll see pink overpasses). That's A.Tuazon...

Go straight, you'll see Rey's Electrical on your left... Just stay on the right lane and you can't miss Paint Tricks on the right... A.Tuazon ain't that long of a road till you reach Sumulong anyway, so it's not hard to spot.
