Painting House should I dilute paint?

Question

using Sandtex

painting render

Answer 1

If the render is new then yes, you should dilute the first layer (you will need to paint it twice). The first coat should be diluted because new render literally sucks all the moisture out of paint. If you paint straight away with paint as is, what tends to happen is the paint dries out too fast and starts flaking/bubbling. The extra moisture in the paint provides the moisture that new render needs and this enables a base, sealing coat to be applied successfully. The second coat should be applied as is, from the can.

If the render is old then no, you should not dilute the paint. However, you will need to take care to prepare the render properly by cleaning it thoroughly to remove any environmental dirt and grease before painting it. Otherwise your paint will not stick and you will end up with a bubbly, flaky mess. Think painting without using sugar soap/washing down & sanding paintwork first...

Answer 2

Scrape off loose or defective area's of existing paint if already painted,prepare, if on new render seal with Sandtex sealer first in order to protect the render from the elements and set a key for the Sandtex paint. Never water down Sandtex paint, paint it on or roller straight out of the tin
This would affect the sealing values of the paint itself.

Answer 3

You can dilute the first coat with clean water, but no more than 20% ( it should say that on the tin )You can add a small amount of water to the 2nd coat too just to help it flow. Just a quick note, if you use undiluted paint on a hot day, after time the paint will simply crack or craze, due to drying too fast.
You'll do just fine Im sure

Answer 4

Sandtex Exterior Paint

Answer 5

Water based discomfort - while water is further to color, the forged content textile of the gadget is diluted. as a consequence, the diluted paint won't style as thick a dry movie as a results of fact the paint producer meant. considering that movie thickness is important to sturdiness, those paints will carry out poorer than expected. Oil-based teeth paints are suited diluted with paint thinner. each paint producer delivers distinctive thinning training for their products, so it quite is nice to stick to their specs. those training are got here across on their labels.

Answer 6

Only if the render is new - you will then have to paint it twice - once with the diluted paint then second with full strength.

Answer 7

Exactly as # 1 and 2 state, NO!

Paint is manufactured and designed at its thickness/substance/body,,, for a reason, and within it there are those agents that give it the neccesary properties as stated on labels and in advertising. To dilute it degrades it.

Think of a glass of Iced tea. You enjoy it so much that you want more, but it's the last glass from the pitcher, so you refill the glass with water half way. What might you assume happens to the substance and quality of the tea?

Answer 9

Answer 10

Don't use Sandtex, use Dulux weathershield exterior smooth masonery paint. It is horrendously expensive, but generally one coat does the job, and in answer to your question NEVER dilute paint,it takes the body out of it. I painted a house that I rent in 1992, and I have just recently had to apply ONE coat to bring it back to its pristine appearance. I can give you further advice if you require.
