Question: Whenever I make wallpaper paste the paste comes out lumpy. What am I doing wrong?
Answer: You are either adding all of the wallpaper paste powder to the water at once or you are adding water to the wallpaper paste. Try adding a little wallpaper paste powder to the water, and stirring, more powder to the water and more stirring.
Don’t add additional wallpaper paste powder to the water until the powder that you have added has been completely blended into the water.
