EverBuild 406 Stabilising Solution 5 Litre

Product Information

Scrape off as much as you can and let it dry-out naturally, which could take a long time, before attempting to redecorate. However, once it’s rubbed the surface below is relatively solid. I am worried that if I paint the surface with sandtex it could bubble if I don’t stabilise. I have tried stabilising solution and PVA but the problem keeps recurring. Any suggestions to prevent this happening would be helpful. Eventually I repainted with a water based masonry paint. Every year since then the paint has bubbled and I have had to scrape and repaint. Kingfisher “Weatherflex Stabilising Solution” is a solvent-free, fine particle, pure acrylic ester copolymer primer, sealer and stabiliser for masonry.

This moisture may force itself out eventually and cause the paintwork to bubble and/or subsequently flake-off. You should then be able to paint the wall as normal with 2 regular coats of masonry paint but keep an eye out for any signs of bubbling in the weeks after. This would indicate a high density of moisture content that is trying to force its way out.One coat should normally be sufficient but very porous surfaces may require additional coats. Drying time will vary depending on the ambient temperature, but normally 4 – 8 hours should be allowed for each coat to fully dry. For the best results allow surfaces to cure for a minimum of 24 hours before applying the Weatherflex Smooth Masonry Paint. DO NOT apply when air or surface temperatures are below 8 °C.

Below is a sample of questions received on the subject of stabilising primers… White dust on stonework? I am about to re-paint some stonework outside my house. It has previously been painted, but in areas it is a little flaky and kind of like white dust build up, think it’s salt or something like that. For larger areas of filler I roughly smoothed over, then again used the paintbrush to texture and blend in the filler. Just scraping over with a knife will leave a smooth area which will show through the paintJust bear in mind that the stabilising solution will impair the breathability of the finishing coats so only apply to areas where it’s really necessary. This usually ensures that the walls have had sufficient time to dry-out in depth and that any loose material is washed away naturally when it rains. Using a stabiliser where not absolutely necessary can impede the performance of any subsequent coats because it isn’t ‘breathable’ and may keep any natural moisture trapped beneath the wall’s surface.

I was doing same repair work prior to painting a couple of weeks ago, used the Toupret Ex filler , it's superb Would you ever used a watered down first coat on areas of render that are dry and chalky so have been treated with stabilising solution? When you have removed as much loose material as possible, treat the worst affected areas with a stabilising solution which will bind any reaming loose martial, presenting you with a solid surface on which to paint. Only do this on the very worst affected areas though. I plan to use Macpherson powerkote, hopefully three coats to give it a strong finish. Do you think the powerkote will be suitable to use? An algebraic Riccati equation is a type of nonlinear equation that arises in the context of infinite-horizon optimal control problems in continuous time or discrete time.The white dust is probably efflorescence – moisture in the stonework will draw out any salts and, provided this isn’t excessive, is perfectly normal. Regular masonry paint is formulated to allow small levels of moisture to escape through evaporation. It’s important, therefore, to avoid the use of sealers or primers unless absolutely necessary. If this be the case then scrape off any loos paint, allow to dry out over a period of a few weeks and paint again. You may well find this is an ongoing process or it may be isolated to one or two problem areas. Furthermore, the stabilising solution and PVA will both act to keep any moisture within the concrete, hence why you experiencing problems. The moisture will force its way out eventually. Remove as much as the dust as you can with a dry brush and scraper and see how it looks. If the surface is fairly solid try priming it with a thinned coat of masonry paint. If that goes OK proceed with over-painting. If it’s still loose you may have to seal the areas affected with a stabilising solution – but only as a last resort.
