MASTER Sanding Cabinets. Foam Abrasives 101

What happens here

The video concludes by comparing foam abrasives with FilmTek abrasives for different paint prep scenarios. While foam is highly effective for profiles, for achieving an 'ultra-flat surface' and aggressively cutting down grain (e.g., on oak cabinets to eliminate the visible grain profile), FilmTek abrasives are recommended. FilmTek is a more aggressive material that offers a superior flat cut. The 1/2 inch foam, due to its open-cell flexibility, loses some cutting power on flat surfaces because the abrasive recedes into the foam. For situations demanding maximum flatness and aggressive material removal, FilmTek provides the best performance, combining the fine finish of paper with the durability of cloth, ensuring a quick and flat sanding process. For general in-between coat sanding and profiles, foam is suitable, but FilmTek excels for the initial aggressive cut-down and ultra-flat finishes.

Goal: Select the best abrasive type for specific surface preparation tasks (flatness, grain elimination, or profiles).

able to use a machine and even in large cabinet companies now you'll see them on a sanding on a line with that machine going to work just like your customers do you know when they're refinishing a cabinet yeah and I notice and when you're talking about loading um when I'm doing like a say a full set of kitchen cabinets the um half inch sponges I don't think I use more than three of them and they don't load they don't rip and tear and so it's kind of amazing because I don't know how Unida makes any money doing this because we just sell a lot of them yeah because I I don't go through very many of them it's amazing how long they last they don't load and stuff so it's if you haven't tried them the three by four sander coupled with a half inch sponge it is literally a game changing tool you got to give it a try and I think you you touched on that I think um you'll shake your Sal doors if you've got any flat sanding these things work for that too but I think you know um I guess if you could touch on it just a little bit you know if you're trying to eliminate grain like on an Oaks outdoor are you going to stand with a um half inch spawn if you want a flat surface I mean is that ideal or not ideal um if it's a relatively flat part I would not use a half inch the problem the thing about half inch it's great for the profiles but you lose a lot of cut it's not nearly as aggressive as your 10 millimeter and your five millimeter will be in fact I would only recommend it for for profiles a lot of times Crown moldings is nice but you do lose a lot of cut because it's receding so much back into the foam whereas these are going to be a lot firmer a lot firmer and for us you know you want to firm a surface as you can get when you're sanding it's just it's a better platen it's a nice hard surface to sand on so that's definitely going to do better on on on something flat as far as cutting down the grain yeah when we're trying to eliminate grain especially like on old cabinets it's pretty popular to take oak cabinets um grain fill them sand them and then a lot of the customers don't even want them to have that profile the oak I mean I'm actually going to instead of a foam abrasive I'm using uh unida's film Tech and film Tech is something better for just really getting that Ultra flat surface yeah if you want to flatten out you still coat it is always going to be more aggressive and like you said that film Tech to me is I know I'll talk a lot about it but it's just my favorite…
