For All Your Questions
Applicable on multiple surfaces, including concrete, plaster, pebbledash, brick, and stonewalls. This broad coverage of HQC Exterior Wall Insulating Paint makes it the first choice of consumers.
To prepare your wall to use HQC Exterior Wall Insulating Paint, a few preliminary steps must be performed. They depend on the wall type under consideration:
To prepare the brick wall, you must:
For the Pebble Dash walls, masonry paints might be the best option to use, but they won’t work if your pebbledash wall isn’t adequately prepared. So, here’s what you need to do:
HQC Exterior Wall Insulating Paint is not filler, so any cracks or damages that your wall has won’t be automatically filled by the paint coats. Instead, they would do worse. Once the paint dries on an unprepared wall, it will make the crack prominent. Even the paint will be sucked in by the cracks, making the inside moist. To avoid this problem, look for the gaps or damage in your walls. Repair them with filler, or you might have to ask professional help to manage them.
Now clean the wall properly using the wire brush. It will remove the dirt particles and other protruding elements from the wall that might hinder the perfect look of your paint.
You can apply these tips to any wall type. So, let’s see:
Seal the cracks: Whether you find these cracks minor or significant don’t leave them as it is. You just use the permanent acrylic sealant to cover these cracks. It will not only make your wall surface smooth but will also make the paint look better.
Damp walls: Find the primary source of dampness and rectify it before you start painting. Blistering, flaking, or moulding could be the potential signs of a wet wall. If you already have these signs, then apart from treating the source, you’ll have to fix each one of them:
Mould: Wash the affected area with HQC Weathershield Multi-Surface Fungicidal Wash. Leave it for 24 hours before scrubbing the mould off the wall.
Blister – it is caused when the wall isn’t allowed to dry properly before painting. The solution to it is to scrub the blistered paint till you get a smooth surface. Use the HQC universal primer to cover the surface. Now use a thinned colour coat to cover the entire wall before you start the regular paint.
Cracks – open the cracks a bit with a scraper. Apply the filler and dampen it to let the filer work properly. Rub it down when it dries to create a smooth surface. Apply primer and paint it.
Under normal conditions, this paint provides coverage of up to 14m2 per litter if painting a single coat or 7m2 for two coats.
Once your wall is ready for the paint, apply a coat of primer to provide an added layer of protection to the wall and a binding agent for the paint. One of the best primers that work on all types of walls and complements the HQC Exterior Wall Insulating Paint is HQC universal primer. On the areas where the brick wall seems more worn out, you might need multiple coats.
The use of primer is not essential, but it can give your paint a better look. A primer is usually applied on unpainted surfaces and dry plasterboards. You might want to use it as an adhesive to ensure better paint sticking. Besides, it works well on the damaged surface, as discussed in the wall damage repair section above.
The application of masonry paint is simple.
It will take 2-4 hours in general circumstances for the paint to dry.
If you choose to thin the paint (Optional)
Thinning the masonry paint can enhance the coverage and paint’s effectiveness. If you want it to be part of your painting process, we recommend it in the following proportion. Up to 1 part, clean water to five parts paint allows enough thinning of the paint to cover a bare surface.
