Just put a small 7ft x 6ft uPVC on the back of the bungalow, there was already a patio area with slabs over a hard core/cement base so rather than digging out foundations the porch sits over the slabs. To seal any damp that might come up through the slabs I did some research about damp proof course products and went for Drybase as it was available in an easy to apply liquid with a brush or roller, I used a brush. It also dries very quickly and has hardly any odour. I liked the fact it not only protects against damp but also various harmful gases. I cleaned the slabs before application and although 2 coats are recommended to be on the safe side and to fill in the tiny gaps between the slabs I put 4 coats on. Criss crossing coats. It took about 6hours altogether from application to completion. I'm very pleased with the finish, it feels warm to the touch, the gaps are sealed between the slabs and where the bottom of the walls join the floor. The temperature outside when I did it was around 20C. I laid the vinyl flooring the next morning and an outdoor rug just protect the vinyl a bit. It really is brilliant stuff. In fact it's so good I've used some of it to repaint the top of my large air source heat pump, because the window installers had scratched the paint off when fitting a new kitchen window and I didn't want the AHP cover to rust. In fact I've only just painted the AHP top cover and it's just 10C outside maybe a bit less, and the Drybase still took less than an hour to dry between coats. It's not meant to be used in this way, but seeing as I'd bought a 5L can and only used about 1L I thought I might as well use some of it up. I believe from memory the shelf life once opened is about 2years if kept sealed and in a dark cool shed or outbuilding. I read that the life of the product used on the actual floor is about 2-3yrs so I'll give the porch floor another 4 coats in 2 years time whether it needs it or not. So yes I'd recommend this product, the hardest thing was getting the lid off and putting it back on again. Oh and it goes a looooong way, so I'd recommend getting a 1L tin to start, because that's all I used and ended up with 3/4 of a tin left over. And if you do need to get a second tin 2 x 1L tins are only £40 so cheap enough for a professional finish!

Working well so far on a problem wall. It took a few coats so unable to finish the whole wall with a one litre. I have bought the bigger can now.

The Drybase Liquid Damp Proof Membrane is an outstanding product that truly lives up to its promises. I recently used this on a problem area in my home, where dampness had been an ongoing issue, and the results were impressive. Applying the paint was straightforward. The consistency is just right—not too thick, so it spreads easily, but not too thin either, ensuring solid coverage. The 1-litre can be enough to cover a decent-sized area, and the white colour provided a clean, bright finish. It dried quickly and left a smooth, even layer that looked great. What really impressed me was how effectively this paint sealed the walls and floors, creating a reliable barrier against moisture. Since applying it, I’ve noticed a significant reduction in dampness, and my walls have stayed dry even during wet weather. It's clear that this product is doing its job perfectly. If you're dealing with damp issues in your home, I highly recommend the Drybase Liquid Damp Proof Membrane. It’s a quality waterproofing solution that provides both peace of mind and a professional finish. I'll definitely be using it again for any future projects!

My old brick shed, although previously painted inevitably started to degrade and the damp penetrated the wall in several areas. After cleaning, wire brushing and allowing for drying it was time to test the Drybase Liquid Damp Proof Membrane. Application is very easy and clear guidance is included on the tin. Paint the first coat in one direction, (up/down), allow time to dry and then paint the second coat in the other direction (left/right). The product is fantastic and will seal and waterproof the bricks and small gaps whilst still allowing them to breathe. I chose white as the colour and the finish is fantastic and certainly does not require painting. You can paint over the top if you like. The 5 litre tin was easily enough to complete the task with some left over. A massive 5 stars for this product

Easy to apply and does what it says on the tin. Stops water from rising where damp once got through. The paint goes on like any other but dries like a layer of rubber. It's easy to clean off hands and off surfaces it wasn't intended to get on. Great value for the price and did exactly what I wanted it to do

Ich habe mein Wohnmobil damit versiegelt, da der Vorbesitzer das Dach und die Alkove neu verspachtelt hatte. Diese war jedoch so rau, dass sich immer wieder Schmutz und dreck dort absetzte. Die Konsistenz ist dünner als gedacht, aber schön streich- und rollfährig. Da ich heute erst gestrichen habe, kann ich zur Schmutzabweisung noch nichts sagen. Update von Feb. 2025: die Farbe ist inzwischen etwas abgedunkelt und nicht mehr so strahlend weiß (somit sieht es nicht mehr so künstlich aufgebessert aus). Noch immer bin ich sehr begeistert. Das Wohnmobil ist dicht und wird auch nicht mehr dreckig. Der Schmutz wäscht sich durch den Regen eigenständig ab. Ich bin sehr zufrieden 👍🏼

3 dagen op rij zouden ze zogezegd leveren, dan zonder reden bestelling gecancelled, ze kwamen of met een excuus dat ik maar een afhaalpunt had moeten selecteren ipv. mijn eigen woning... Ook iets dat de regio niet bereikbaar zou zijn (wat compleet verzonnen was, er was geen enkel excuus). De verzonnen excuses maken het nog een stuk erger.
