Second coat of paint is on! We used the Dulux Brilliant White Silk at first but discovered that the pot was lumpy and would not stir smooth. It had small hard lumps in the mixture. That pot went back and got our money back! We continued with the new pot covering all walls, both upper and lower sections. It is interesting to report that even after the second coat of Dulux on top of the B&Q Premium, it is still noticeable that the white is not as white as the double coat of Dulux on the upper sections of the walls. It is likely that we will do a third coat especially on the lower sections! Reading the Dulux web site does indicate that on brand new walls it is recommended to apply three coats with the first one slightly diluted. The B&Q Premium could be treated as this diluted first coat then!
We forgot to do a light level test this evening and we want to continue with the third coats tomorrow so we will take some recordings after the third coat instead!
