I want to paint my house, brushing is hard work, should I look at a conventional, airless or HVLP sprayer to make it easier?
Please remember I have never used any of these.
If you want to make the task of painting your house easier, you may want to consider using a sprayer. Out of the three options you mentioned - conventional, airless, and HVLP (high volume, low pressure) sprayers - HVLP sprayers may be the best choice for you, especially if you're a beginner. Here's why:

HVLP sprayers are easy to use and control, making them a great option for inexperienced users. They produce a soft, fine mist that's easy to apply, even to hard-to-reach areas, and the low pressure means that you can avoid overspray and drips.

HVLP sprayers are versatile and can be used to paint a variety of materials, including wood, metal, and drywall.

HVLP sprayers are less messy than other types of sprayers, and they're less likely to create a lot of overspray and waste.

However, it's important to keep in mind that HVLP sprayers are slower than airless or conventional sprayers, so if you have a large area to paint, it may take longer to complete the job.
