Dream Builders

I asked SP were gonna prime the table and chairs prior to painting, their response is no we don't need a primer to paint and I asked if they're sure and said yes. I was shocked that they start to paint with brush. sp told me that brush not work and get a sprayer. SP came back but the weather is rainy and asked the if they can work in the garage just make sure that protect everything and started spraying. SP said that they will do the 2nd coat after 2 - 3 hours and I asked if its ready for the 2nd quote by that time. I was surprised to do it rights away. so when they finished, it looks ok but its sticky and floppy. I think that they rushed the job because they wanted to be paid. I called the paint manufacturer just to ensure that it should take 24 hours to dry the touch. However, they still do the job in one day. They need to do work now and they're gonna redo according to them but they asked for 50% payment but I said no and they'd asked for 25% instead and they want to finish it in one day. It is okay for me redo the job but they should not be taking any money from me.
