DRYLOK 90237 Synthetic Bristle Masonry Brush, 4-Inch, 4 Inch, White

Holy moley! This brush worked perfectly on my cinder block wall. Drylok has done a great job of creating a brush that is the correct firmness/thickness to apply their product. Much less effort than one of those stiff bristle brushes. Washed up well with soap and water. The only thing - I had to use a small trim brush to get into a corner near the garage door. It would be great if Drylok would make this brush available in a 2" size for trimming and hard to access areas.

What a great brush. Zero bristles lost in process and durable Painted the lower part of my home with this brush.

While it did the job of applying the thick drylok paint, it was extremely difficult to clean. Ultimately it took 4 tries including soaks in paint thinner and hot water with soap to make it usable again.

Used the brush to paint dry lock into our basement cinder block wall. The paint is thick, and the brush appears to be designed to apply such a thick paint. The paint (and dry lock cement) worked well, btw, in fixing our basement water leak coming in from outside. Cost of the brush is comparable to a regular brush.

Just what I needed. Can’t find it in any hardware shop. This will last me a long time.

I'm currently applying the paint made by the producer of this brush. Interior basement wall. it's an experience you do not want to have, if you can avoid it. But: I would say it is impossible to do without this brush. if I could give it 10 stars, instead of 5, I would. The paint application calls for 'stabbing' the paint into the concrete pours. Ordinary brushes are useless. Typical masonry brushes are too wide and lack 'structure.' The application process is so brutal that one should think of this brush as a one (or two) time use tool. But I've rarely been so glad to have exactly the required tool as I am, now, using this brush for my paint project. 1000% endorsement.

I love this brush! I am applying Drylok over an inside wall, above grade, just mortared over 2 wks ago. This brush holds a decent amount of paint, tends not to drip and most important, does not shed! It cleans up very easy, just cool water and soap. Let dry and ready to use again. As for not dripping, this is more due to technique than anything else. Gravity controls all things, including paint on a brush. The trick is to stay ahead of it and keep turning your brush and applying the paint that is on that side. I only wish that DryLok would make this brush in a 2" cut-in version. Would really help out around the trim and edges inside.

This brush is awesome up until it gets saturated then it transforms into a 20 pound paint club. I found that as it swelled I had to increase the amount of paint I left on the brush which only made the problem worse. Very difficult to clean as the paint loves to hide in the inner bristles which is where I believe a gallon of paint takes up permanent residence. Also, the second one I used had an issue with stray bristles. Had to pull out a lot of them before I even started. I have no alternate recommendations and I’m currently looking for a good stiff bristle brush for painting masonry.

Pro.....with Drylok paint!

Good product

Sturdy sting brush but 1 time use! You can’t clean the paint from it as the paint repels water.
