Drylok90237 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.

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.

Very nice texture. Paint got into holes and cracks. Very easy to use

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.

It’s a good brush especially after you wash it off.

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.

You'd think a paintbrush is just a paintbrush, but I have never disliked one so much. We bought this specifically to apply the manufacturer's own masonry waterproofing paint in our basement, and while it does the job, it doesn't do it that well.With enough force, it will flex enough to get into divots and pinholes and still return to its shape (the only positive), but it's so thick that you'll hit every surface around it in the attempt (and may not even hit your target). Definitely not good for tight spaces.This thing is also a BRICK. Once it's got the paint loaded on it weighs an absolute TON. This, coupled with the fact that it's awkwardly sized for smaller hands,* means our hands were ACHING after only a couple of feet of progress. By the end of it (roughly 225 sqft of wall), I couldn't flip the brush in my hand without using my OTHER hand to do it. My thumb was pretty much useless.(*For reference our hands are roughly 3.5" wide and 7" long from palm heel to fingertip.)I'll add that I think the other reviewers are right, that it swells up with paint that you can't even see. I would put a reasonable amount on the brush, and it would start dripping after a couple of swipes (after I'd already applied the majority to the wall), as I was working it into grooves. The only way we found to counter it - other than watching it like a hawk and rotating the brush like a rotisserie - was to just put VERY little on the brush. (Which means dipping into the paint 3 times as often and spreading out the job time enormously!)I mean, we'll use it because we've got it, but if - God-forbid - I ever have to paint masonry again, I won't pick this brush to apply it.

Starts out great then it starts to hold the paint and gets caked up so bad, very hard to paint with then, then when cleaning the ends frayed after one use, and hard to get the caked up paint out.

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.
