Is your gypsum cracking too soon? Or maybe it's not sticking well to walls? These common problems can be fixed with the right gypsum application additives. LANDU offers special chemicals that make your gypsum work better!
Gypsum application additives are special chemicals that improve how gypsum works. They make gypsum easier to use and help it last longer. Think of them as "power-ups" for regular gypsum!
"The right additive can double the working time of gypsum while also making the final product stronger and more water-resistant."
LANDU makes four main types of gypsum application additives. Each one helps in a different way:
HPMC (Hydroxypropyl Methyl Cellulose) and HEMC (Hydroxyethyl Methyl Cellulose) are water-keeping helpers. They:
For example, adding just 0.2% HPMC to your gypsum mix can extend working time from 30 minutes to 60 minutes. This gives you plenty of time to get a smooth finish.
RDP is like adding tiny rubber bands to your gypsum. These additives:
Many people find that RDP makes their gypsum board much less likely to crack when nailed or screwed.
A gypsum retarder is like a "slow down" button for setting time. These additives:
With a good gypsum retarder, you can mix larger batches without worrying about the material hardening before you can use it all.
SHP makes gypsum hate water (hydrophobic). This means:
Gypsum putty needs to be smooth and easy to apply. The best additives for putty are:
1. LANDERCOLL HPMC/HEMC: Makes putty creamy and easy to spread
2. ACCURATE RDP: Prevents cracking after drying
3. NOVASTAR PCE (Polycarboxylate Ether): Reduces water needs while keeping good flow
Joint fillers need to stick well and not shrink. The most helpful additives are:
1. LANDERCOLL HPMC: Prevents too-quick drying
2. ACCURATE RDP: Improves flexibility and prevents cracks
3. NOVASTAR Gypsum Retarder: Gives you time to smooth joints perfectly
Gypsum boards need strength and water resistance. The best additives include:
1. LANDERCOLL HEMC: Gives uniform setting throughout the board
2. ACCURATE RDP: Makes boards more impact-resistant
3. NOVASTAR SHP: Creates water-resistant boards for bathrooms
