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!

What Are Gypsum Application Additives?

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."

Types of LANDU Gypsum Application Additives

LANDU makes four main types of gypsum application additives. Each one helps in a different way:

LANDU-Hydroxypropyl-Methyl-Cellulose-Product
LANDU-LANDERCOLL-Hydroxyethyl-Methyl-Cellulose

01

LANDERCOLL Cellulose Ethers (HPMC and HEMC) for Gypsum

HPMC (Hydroxypropyl Methyl Cellulose) and HEMC (Hydroxyethyl Methyl Cellulose) are water-keeping helpers. They:

  • Keep water in the mix longer
  • Make gypsum paste smoother and easier to spread
  • Stop the gypsum from drying too quickly
  • Help gypsum stick better to walls

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.

02

ACCURATE Redispersible Latex Powder (RDP) for Gypsum

RDP is like adding tiny rubber bands to your gypsum. These additives:

  • Make gypsum more flexible so it doesn't crack
  • Improve bonding strength by up to 40%
  • Create a smoother finish
  • Help gypsum resist impacts better

Many people find that RDP makes their gypsum board much less likely to crack when nailed or screwed.

NOVASTAR Gypsum Retarder

A gypsum retarder is like a "slow down" button for setting time. These additives:

  • Give you more time to work with the gypsum
  • Help with larger projects where you need extra working time
  • Allow better smoothing and finishing
  • Reduce waste from premature hardening

With a good gypsum retarder, you can mix larger batches without worrying about the material hardening before you can use it all.

04

NOVASTAR Silicone Hydrophobic Powder (SHP)

SHP makes gypsum hate water (hydrophobic). This means:

  • Gypsum resists water damage
  • Mold growth is reduced
  • The final product lasts longer in humid areas
  • It works well in bathrooms and kitchens

How These Additives Help Different Gypsum Products

Gypsum Putty Additives

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 Filler Additives

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 Board Additives

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
